AB  - Gut microbiota contribute to shaping the immune repertoire of the host, whereas probiotics may exert beneficial effects by modulating immune responses. Having in mind the differences in both the composition of gut microbiota and the immune response between rats of Albino Oxford (AO) and Dark Agouti (DA) rat strains, we investigated if intraperitoneal (i.p.) injection of live Lactobacillus rhamnosus (LB) may influence peri-toneal cavity cell response to invitro treatments with selected microbiota in the rat strain-dependent manner. Peritoneal cavity cells from AO and DA rats were lavaged two (d2) and seven days (d7) following i.p. injection with LB and tested for NO, urea, and H2O2 release basally, or upon invitro stimulation with autologous E.coli and Enterococcus spp. Whereas the single i.p. injection of LB nearly depleted resident macrophages and increased the proportion of small inflammatory macrophages and monocytes on d2 in both rat strains, greater proportion of MHCIIhiCD163− and CCR7+ cells and increased NO/diminished H2O2 release in DA compared with AO rats suggest a more intense inflammatory prim-ing by LB in this rat strain. Even though E.coli- and/or Enterococcus spp.-induced rise in H2O2 release invitro was abrogated by LB in cells from both rat strains, LB prevented microbiota-induced increase in NO/urea ratio only in cells from AO and augmented it in cells from DA rats. Thus, the immunomodulatory properties may not be constant for particular probiotic bacteria, but shaped by innate immunity of the host.

AB  - The systemic and extra- gonadal levels of 17 beta-estradiol (E2) change during aging, and affect the expression of estrogen receptors (ERs) in the immune cells of both females and males. The age-related cessation of ovarian function in females, as well as the tissue-specific expression of enzyme aromatase (estrogen synthase which significantly rises with the advancing age) in both males and females, both determine the concentration of E2 to which immune cells may be exposed. The present study was set up to investigate the direct influence of E2 in vitro on the secretory profile of peritoneal macrophages from young and naturally menopausal female rats, and from young and middle-aged male rats. The involvement of receptor(s) responsible for mediating the effects of E2 in vitro was examined by use of antagonists specific for ERa or ER beta. Whereas in macrophages from young female rats E2 treatment diminished interleukin (IL)-1 beta secretion, it increased it in young males, and the middleaged females. The in vitro E2 treatment increased tumor necrosis factor (TNF)-alpha release by macrophages from young rats of both sexes, while it increased macrophage IL-6 release independently of both sex and age. At the same time, E2 decreased hydrogen peroxide (H2O2) production in macrophages from females, and increased it in male rats of both ages, whereas it diminished nitric oxide (NO) release in all experimental groups. Inspite of the sex-and age-specific effects of E2 on macrophage urea release, E2 did not affect the NO/urea ratio in macrophages from female rats, and diminished it in macrophages from both young and middle-aged male rats. Independently of the sex and age, E2 stimulated the release of inflammatory cytokines predominantly via macrophage ER alpha, and inhibited the IL-1 beta release in young females via ER beta. In contrast, E2 increased macrophage H2O2 and urea production by activating ER beta, but diminished their release via ER alpha. Our study may contribute to better understanding of the complex role(s) that E2 may play in innate immunity during aging, and that are dependent of sex.

AB  - Aims: Some gut commensals can be protective, whereas others are implicated as necessary for development of inflammatory/autoimmune diseases. Peritoneal immune cells may play an important role in promoting auto-immunity in response to gut microbiota. This study investigated the phenotype and the function of peritoneal immune cells in the autoimmunity-resistant Albino Oxford (AO), and the autoimmunity-prone Dark Agouti (DA) rat strains upon stimulation with their own colonic E. coli or Enterococcus. Main methods: Rats were intraperitoneally injected with their own E. coli or Enterococcus. Peritoneal cells isolated two days later were tested for nitric oxide (NO) and cytokine production, and for arginase and myeloperoxidase (MPO) activity. The phenotype of cells was determined using flow cytometry. Key findings: While the Enterococcus injection did not affect the composition of peritoneal cells in AO rats, the E. coli treatment increased the percentages of activated CD11b(int)HIS48(hi) neutrophils, and decreased the proportion of resident (CD11b(hi)HIS48(int/low), CD163+ CD86+) and anti-inflammatory CD68+ CD206+ macrophages. E. coli increased the production of NO and urea, but preserved their ratio in cells from AO rats. Conversely, both E. coli and Enterococcus diminished the proportion of resident and anti-inflammatory macrophages, increased the proportion of activated neutrophils, and induced inflammatory polarization of peritoneal cells in DA rats. However, injection of E. coli maintained the ratio of typical CD11b(int)HIS48(int) neutrophils in DA rats, which correlated with the sustained MPO activity. Significance: The rat strain differences in peritoneal cell response to own commensal microbiota may contribute to differential susceptibility to inflammatory/autoimmune diseases.

AB  - The aim of this study was to examine the influence of sex on age-related changes in phenotype and functional capacity of rat macrophages. The potential role of estradiol as a contributing factor to a sex difference in macrophage function with age was also examined. Thioglycollate-elicited peritoneal macrophages derived from the young (2 months old) and the naturally senescent intact middle-aged (16 months old) male and female rats were tested for cytokine secretion and antimicrobial activity (NO and H2O2 production and myeloperoxidase activity). Serum concentration of estradiol and the expression of estrogen receptor (ER)alpha and ER beta on freshly isolated peritoneal macrophages were also examined. Decreased secretion of IL-1 beta and IL-6 by macrophages from middle-aged compared to the young females was accompanied with the lesser density of macrophage ER alpha expression and the lower systemic level of estradiol, whereas the opposite was true for middle-aged male rats. Macrophages in the middle-aged females, even with the diminished circulating estradiol levels, produce increased amount of IL-6, and comparable amounts of IL-1 beta, TNF-alpha, and NO to that measured in macrophages from the middle-aged males. Age-related changes in macrophage phenotype and the antimicrobial activity were independent of macrophage ER alpha/ER beta expression and estradiol level in both male and female rats. Although our study suggests that the sex difference in the level of circulating estradiol may to some extent contribute to sex difference in macrophage function of middle-aged rats, it also points to more complex hormonal regulation of peritoneal macrophage activity in females.

AB  - Rats of Albino Oxford (AO) strain in our animal facility exhibit a longer average healthy life span than rats of Dark Agouit (DA) strain. Since chronic activation of macrophages contributes to chronic low level inflammation common in older age, elucidation of the changes in middle-aged rats could be useful in prevention of unbalanced inflammatory response in advanced age. We have analysed the phenotype of unelicited and thioglycollate-elicited peritoneal macrophages from young and middle-aged DA and AO rats and tested functions of these cells following stimulation with lipopolysaccharide (LPS) in vitro. Unelicited cells from middle-aged DA rats produced higher amounts of proinflammatory mediators interleukin-6 (IL-6) and nitric oxide (NO), but have a diminished response to LPS stimulation then cells from young rats, in spite of increased frequency of TLR4- and CD14-expressing mature macrophages. Injection of thioglycollate robustly increased overall cytokine production in young rats' macrophages, while diminishing their response to LPS stimulation. In middle-aged DA rats injection of thioglycollate diminished IL-6 production, but increased it in response to LPS stimulation. Quite the contrary to DA rats, the macrophages from middle-aged AO rats have released diminished levels of TNF-alpha, and NO, whereas urea production was strongly increased, when compared to the macrophages from young rats. Although the thioglycollate injection has increased the proportion of CD86(+)MHCII(+) mature macrophages in young rats, and percentages of activated TLR4(+) macrophages in both age groups of AO rats, it has not affected the cytokine production in young rats' macrophages, and the TNF-alpha production in middle-aged rats' macrophages. Moreover, the injection of thioglycollate has robustly increased the production of urea in macrophages derived from both age groups of AO rats. Although middle-aged rats of both strains were healthy during experiment, differences between the inflammatory responses of peritoneal macrophages of middle-aged rats of these strains might be one of the contributing factors defining their health in their advanced age. Development of strategies for the prevention of undesirable inflammatory changes in the elderly would benefit from the prospective study of the middle-aged. (C) 2016 Elsevier Inc.

Although middle-aged rats of both strains were healthy during experiment, differences between the inflammatory responses of peritoneal macrophages of middle-aged rats of these strains might be one of the contributing factors defining their health in their advanced age. Development of strategies for the prevention of undesirable inflammatory changes in the elderly would benefit from the prospective study of the middle-aged. (C) 2016 Elsevier Inc.

AB  - Macrophages undergo significant functional alterations during aging. The aim of the present study was to investigate changes of rat macrophage functions and response to M1/M2 polarization signals with age. Therefore, resident and thioglycollate-elicited peritoneal macrophages from young (3-month-old) and aged (18-19-month-old) rats were tested for phagocytic capacity and ability to secrete inflammatory mediators following in vitro stimulation with LPS and GM-CSF, and IL-4, prototypic stimulators for classically (M1) and alternatively activated (M2) macrophages, respectively. Aging increased the frequency of monocyte-derived (CCR7+ CD68+) and the most mature (CD163+ CD68+) macrophages within resident and thioglycollate-elicited peritoneal macrophages, respectively. The ability to phagocyte zymosan of none of these two cell subsets was affected by either LPS and GM-CSF or IL-4. The upregulated production of IL-1 beta, IL-6 and IL-10 and downregulated that of TGF-beta was observed in response to LPS in resident and thioglycollate-elicited macrophages from rats of both ages. GM-CSF elevated production of IL-1 beta and IL-6 in resident macrophages from aged rats and in thioglycollate-elicited macrophages from young rats. Unexpectedly, IL-4 augmented production of proinflammatory mediators, IL-1 beta and IL-6, in resident macrophages from aged rats. In both resident and thioglycollate-elicited macrophages aging decreased NO/urea ratio, whereas LPS but not GM-SCF, shifted this ratio toward NO in the macrophages from animals of both ages. Conversely, IL-4 reduced NO/urea ratio in resident and thioglycollate-elicited macrophages from young rats only. In conclusion, our study showed that aging diminished GM-CSF-triggered polarization of elicited macrophages and caused paradoxical IL-4-driven polarization of resident macrophages toward proinflammatory M1 phenotype. This age-related deregulation of macrophage inflammatory mediator secretion and phagocytosis in response to M1/M2 activators may lead to the deficient control of infectious and/or inflammatory diseases in advanced age.

AB  - Problem The influence of unopposed estrogen replacement/isolated progesterone deficiency on macrophage production of pro-inflammatory/anti-inflammatory mediators in the post-reproductive age was studied. Method of study Considering that in the rats post-ovariectomy the circulating estradiol, but not progesterone level rises to the values in sham-operated controls, 20-month-old rats ovariectomized at the age of 10 months served as an experimental model. Estrogen and progesterone receptor expression, secretion of pro- and anti-inflammatory cytokines, and arginine metabolism end-products were examined in splenic and peritoneal macrophages under basal conditions and following lipopolysaccharide (LPS) stimulation in vitro. Results Almost all peritoneal and a subset of splenic macrophages expressed the intracellular progesterone receptor. Ovariectomy diminished cytokine production by splenic (IL-1 beta) and peritoneal (TNF-alpha, IL-1 beta, IL-10) macrophages and increased the production of IL-10 by splenic and TGF-beta by peritoneal cells under basal conditions. Following LPS stimulation, splenic macrophages from ovariectomized rats produced less TNF-alpha and more IL-10, whereas peritoneal macrophages produced less IL-1 beta and TGF-beta than the corresponding cells from sham-operated rats. Ovariectomy diminished urea production in both subpopulations of LPS-stimulated macrophages. Conclusion Although long-lasting isolated progesterone deficiency in the post-reproductive age differentially affects cytokine production in the macrophages from distinct tissue compartments, in both subpopulations, it impairs the pro- inflammatory/anti-inflammatory cytokine secretory balance.

The treatment of adult rats with mast cell-depletor compound 48/80 and neonatal depletion of C-sensory fibers independently revealed that leukocyte composition of the inflamed paws and lymph nodes during local inflammatory response to Con A was generally regulated in a similar way in DA and AO rat strains. However, in DA and AO rats, the decrease and the increase of Con A-induced plasma extravasation were associated with mast cell depletion and activation, respectively, whereas neonatal capsaicin treatment activated dermal mast cells and potentiated inflammatory plasma extravasation only in adult rats of DA strain. Hence, strain differences in Emphasis Type="Strikethrough" the development of the inflammatory response to Con A are probably controlled by the differences in the interplay between mast cells and C-sensory fibers in DA and AO rats.

AB  - In humans, usual aging, differently from successful aging, is associated with deregulation of proinflammatory/anti-inflammatory cytokine balance. The corresponding data from rat studies are limited. Therefore, we examined (i) cytokine messenger RNA (mRNA) profile of fresh peritoneal cells from 6-(adult), 24-(old), and 31-month-old (long-lived) AO rats and (ii) proinflammatory (IL-1 beta and IL-6) and antiinflammatory (IL-10) cytokine, NO, and urea production in their LPS-stimulated cultures. Comparing with adult rats, cells from old ones expressed lower amount of TNF-alpha and IL-6 mRNAs, but greater amount of IL-1 beta mRNA. On the other hand, cells fromlong-lived rats exhibited a dramatic increase in IL-10 mRNA expression followed by diminished TNF-alpha and IL-6 mRNA expression, and comparable expression of IL-1 beta mRNA relative to adult rats. Consequently, IL-10/IL-1 beta mRNA ratio was greater in cells from long-lived rats than in adult and old rats. In LPS-stimulated peritoneal cell cultures (contained = 95 % macrophages) from old rats, concentration of common proinflammatory cytokines was higher than in those from adult rats. Comparing with adult and old rats, in LPS-stimulated macrophage cultures from long-lived rats, TNF-alpha and IL-6 concentrations were lower; IL-1 beta concentration was comparable or greater (in respect to adult rats), whereas that of IL-10 was strikingly higher. Consistently, in macrophage cultures from long-lived rats, NO (iNOS activity marker)/urea (arginase activity marker) ratio was less and not different from that in old and adult rats, respectively. The study suggests that macrophages from longlived rats, differently from those of old ones, have substantial ability to limit proinflammatory mediator production, which may contribute to their longevity.

AB  - Altered functions of macrophages with aging contribute to impairment of both innate and adaptive immunity in the elderly. The present study aimed to examine strain specificity of age-related changes in the phenotypic and functional characteristics of macrophages from DA and AO rats, which differ in average life span. Resident peritoneal macrophages from young (10-12 weeks old) and aged (98-104 weeks old) rats were tested for: (a) the surface expression of TLR4 and CD14; (b) the basal and LPS-induced production of TNF-alpha and IL-10; and (c) the basal and LPS-induced activity of iNOS and arginase, by measuring the levels of NO and urea, respectively, in the culture supernatants. Aging elevated TLR4 macrophage surface density in rats of both strains. Conversely, the age-related decrease in the surface density of CD14 co-receptor was detected only on macrophages from aged DA rats. Accordingly, with aging in DA rats, contrary to AO rats, upon LPS-stimulation both TNF-alpha and IL-10 levels decreased in culture supernatants. However, in rats of both strains TNF-alpha stimulation index (LPS-induced over basal production) remained stable with aging, but it was significantly greater in AO rats. Furthermore, with aging, IL-10 stimulation index decreased and increased in DA and AO rats, respectively. Age-related shift in urea stimulation index complied with the changes of IL-10 stimulation index during aging. In conclusion, the study suggests that the preserved ability of macrophages from aged AO rats to synthesize not only proinflammatory TNF-alpha, but also immunoregulatory IL-10 cytokine most likely contributes to their longer average life compared with DA rats.

abstract = "Altered functions of macrophages with aging contribute to impairment of both innate and adaptive immunity in the elderly. The present study aimed to examine strain specificity of age-related changes in the phenotypic and functional characteristics of macrophages from DA and AO rats, which differ in average life span. Resident peritoneal macrophages from young (10-12 weeks old) and aged (98-104 weeks old) rats were tested for: (a) the surface expression of TLR4 and CD14; (b) the basal and LPS-induced production of TNF-alpha and IL-10; and (c) the basal and LPS-induced activity of iNOS and arginase, by measuring the levels of NO and urea, respectively, in the culture supernatants. Aging elevated TLR4 macrophage surface density in rats of both strains. Conversely, the age-related decrease in the surface density of CD14 co-receptor was detected only on macrophages from aged DA rats. Accordingly, with aging in DA rats, contrary to AO rats, upon LPS-stimulation both TNF-alpha and IL-10 levels decreased in culture supernatants. However, in rats of both strains TNF-alpha stimulation index (LPS-induced over basal production) remained stable with aging, but it was significantly greater in AO rats. Furthermore, with aging, IL-10 stimulation index decreased and increased in DA and AO rats, respectively. Age-related shift in urea stimulation index complied with the changes of IL-10 stimulation index during aging. In conclusion, the study suggests that the preserved ability of macrophages from aged AO rats to synthesize not only proinflammatory TNF-alpha, but also immunoregulatory IL-10 cytokine most likely contributes to their longer average life compared with DA rats.",

AB  - Aims: Macrophages are heterogeneous population of inflammatory cells and, in response to the microenvironment, become differentially activated. The objective of the study was to explore macrophage effector functions during different inflammatory conditions in two rat strains. Main methods: We have investigated the effects of in vivo treatment with mast cell-degranulating compound 48/80 and/or thioglycollate on peritoneal macrophage phagocytosis and capacity to secrete hydrogen peroxide (H2O2), tumor necrosis factor-alpha (INF-alpha) and nitric oxide (NO) in Dark Agouti (DA) and Albino Oxford (AO) rat strains. Besides, fresh peritoneal cells were examined for the expression of ED1, ED2 and CD86 molecules. Key findings: In thioglycollate-elicited macrophages, increased proportion of ED1 + cells was accompanied with elevated phagocytosis of zymosan (DA strain), whereas increased expression level of CD86 molecule on ED2 + macrophages matched elevated secretory capacity for H2O2, TNF-alpha and NO (AO rats). Although mast cell degranulation induced by compound 48/80 increased the percentages of ED2 + macrophages in both rat strains, the proportion of ED2 + cells expressing CD86 molecule was decreased and increased in DA and AO rats, respectively. Furthermore, in DA strain compound 48/80 diminished macrophage secretion of NO, but stimulated all macrophage functions tested in AO strain. If applied concomitantly, the compound 48/80 additively increased macrophage activity induced by thioglycollate in AO rats. Significance: Macrophages from DA and AO rat strains show different susceptibility to mediators released from mast cells, suggesting that strain-dependant predisposition(s) toward particular activation pattern is decisive for the macrophage efficacy in response to inflammatory agents.

AB  - The phenotype and function of tissue macrophages substantially depend on the cellular milieu and biological effector molecules, such as steroid hormones, to which they are exposed. Furthermore, in female rats, aging is associated with the altered macrophage functioning and the increased estrogen level is followed by a decrease in that of progesterone. Therefore, the present study aimed to investigate the influence of estradiol/progesterone balance on rat macrophage function and phenotype throughout whole adult lifespan. We ovariectomized rats at the late prepubertal age or at the very end of reproductive lifespan, and examined the expression of ED2 (CD163, a marker of mature resident macrophages related to secretion of inflammatory mediators) on peritoneal macrophages and their ability to produce TNF-alpha and NO upon LPS-stimulation at different age points. In addition, to delineate direct and indirect effects of estrogen, we assessed the in vitro influence of different concentrations of 17 beta-estradiol on LPS-induced macrophage TNF-alpha and NO production. Results showed that: ( a) the low frequency of ED2(high) cells amongst peritoneal macrophages of aged rats was accompanied with the reduced TNF-alpha, but not NO production; (b) estradiol level gradually increased following ovariectomy; (c) macrophage ED2 expression and TNF-alpha production were dependent on estradiol/progesterone balance and they changed in the same direction; (d) changes in estradiol/progesterone balance differentially affected macrophages TNF-alpha and NO production; and (e) estradiol exerted pro-inflammatory and anti-inflammatory effects on macrophages in vivo and in vitro, respectively. Overall, our study discloses that estradiol/progesterone balance contributes to the fine-tuning of rat macrophage secretory capacity, and adds to a better understanding of the ovarian steroid hormone role in the regulation of macrophage function, and its significance for the age-associated changes in innate immunity.

AB  - New Findings center dot What is the central question of this study? Glucocorticoids modulate extraglandular catecholamine metabolism and adrenoceptor expression in many cell types. Catecholamines modulate the production of inflammatory mediators by macrophages. It was hypothesized that adrenal hormones affect tumour necrosis factor- production in rat macrophages by altering the autocrine/paracrine action of catecholamines. center dot What is the main finding and its importance? In rat macrophages, adrenalectomy increased tyrosine hydroxylase expression, decreased monoamine oxidase-A mRNA expression (due to the absence of adrenal catecholamines and glucocorticoids, respectively) and augmented 2-adrenoceptor expression (due to lack of adrenal catecholamines). However, notwithstanding these changes, propranolol treatment increased lipopolysaccharide-stimulated tumour necrosis factor- production in macrophages from adrenalectomized and non-operated rats to a similar extent. Catecholamines modulate the production of inflammatory mediators by macrophages in an autocrine/paracrine manner. They also tune 2-adrenoceptor expression. Glucocorticoids influence catecholamine metabolism and adrenoceptor expression in many cell types. We hypothesized that adrenal hormones affect the production of tumour necrosis factor- (TNF-) and NO by macrophages by altering the modulatory influence of catecholamines. To prove the hypothesis, peritoneal exudate macrophages from propranolol-treated non-operated and adrenalectomized rats and from corticosterone-supplemented adrenalectomized rats were examined for lipopolysaccharide-stimulated NO and TNF- production in vitro and for expression of 2-adrenoceptors and major catecholamine-metabolizing enzymes. Glucocorticoid deprivation increased NO production by macrophages, whereas 4 days of propranolol treatment was ineffective in this respect. However, propranolol treatment, via 2-adrenoceptor blockade, increased production of TNF- by macrophages in both non-operated and adrenalectomized rats (showing dramatically enhanced TNF- production due to a lack of circulating glucocorticoids) for the same value. The expression of 2-adrenoceptor was increased in peritoneal macrophages that were freshly isolated from non-operated, propranolol-treated and adrenalectomized rats (due to adrenal catecholamine deficiency). Propranolol did not affect macrophage 2-adrenoceptor expression in adrenalectomized rats. Given that propranolol increased the density of macrophage tyrosine hydroxylase expression only in non-operated rats and affected the mRNA expression of monoamine oxidase-A in neither non-operated nor adrenalectomized animals, a significant influence of propranolol on peritoneal exudate cell noradrenaline content was found only in non-operated rats. A lack of circulating adrenal hormones also affected noradrenaline metabolism and content in peritoneal exudate cells including macrophages. Collectively, despite differences in the abundance of macrophage catecholamine2-adrenoceptor system components and in the TNF- response to lipopolysaccharide between adrenalectomized and non-operated rats, propranolol increased TNF- production by the same amount in macrophages from these two groups of animals.

AB  - The present study tests the hypothesis that the difference in the intensity of paw edema found between the Dark Agouti (DA) and Albino Oxford (AO) rat strains originates from the distinct participation of histamine, serotonin and their corresponding receptors in Concanavalin A (Con A)-induced inflammation. DA and AO male rats were intraplantarly injected with specific receptor antagonists prior to Con A, and the intensity of inflammation was determined by measuring the paw diameter. Our results have showed that histamine H1 and H2 receptor antagonists reduced the Con A-induced paw edema in DA rats, while serotonin 5HT3 receptor antagonist diminished the inflammation in both DA and AO rat strains. The calcium channel blocker did not change Con A-induced inflammation. Strain differences in the intensity and kinetics of inflammation observed between the DA and AO rats are most likely defined by the diversity of mediators released and their receptors activated upon Con A injection.
AB  - Testirana je hipoteza da razlike u intenzitetu inflamatornog edema šape indukovanog konkanavalinom A u pacova Dark Agouti (DA) i Albino Oxford (AO) soja potiču od različitog doprinosa histamina i serotonina i njihovih odgovarajućih receptora. Mužjaci pacova DA i AO soja su intraplantarno tretirani antagonistima specifičnih receptora pre izazivanja inflamacije konkanavalinom A i intenzitet inflamacije je praćen merenjem dijametra šape. Naši rezultati su ukazali da antagonisti histaminskih H1 i H2 receptora smanjuju edem šape indukovan konkanavalinom A u DA pacova, dok antagonist serotoninskih 5HT3 receptora smanjuje edem šape u oba soja pacova. Blokator kalcijumskih kanala ne utiče na inflamaciju izazvanu konkanavalinom A. Razlike u intenzitetu i kinetici inflamatornog odgovora indukovanog konkanavalinom A između DA i AO sojeva su najverovatnije posledica razlika u oslobođ enim medijatorima i aktivaciji odgovarajućih receptora nakon injekcije konkanavalina A.

AB  - Neuropeptide Y (NPY) has been reported to be a potent anti-inflammatory peptide with ability to directly modulate activity of granulocytes and macrophages. The present study aimed to correlate the effects of NPY in vivo on lipopolysaccharide-induced air-pouch exudates cells and in vitro on peripheral blood leukocytes functions. The role of different Y receptors was examined using NPY-related peptides and antagonists with diverse subtype specificity and selectivity for Y receptors. Y1, Y2 and Y5 receptors were detected on air-pouch exudates cells (flow cytometry) and peripheral blood granulocytes (immunocito-chemistry). NPY in vivo reduced inflammatory cells accumulation into the air pouch, and decreased their adherence and phagocytic capacity via Y2/Y5 and Y1/Y2 receptors, respectively. Quite the opposite, NPY in vitro potentiated adhesiveness and phagocytosis of peripheral blood granulocytes and monocytes by activating Y1 receptor. The differences between in vivo and in vitro effects of NPY on rat inflammatory cells functions are mostly due to dipeptidyl peptidase 4 activity. In addition, suppressive effect of NPY in vivo is highly dependent on the local microenvironment, peptide truncation and specific Y receptors interplay. (C) 2011 Elsevier Inc. All rights reserved.

AB  - It has been acknowledged that aging exerts detrimental effects on cells of the innate immune system and that neuropeptides, including neuropeptide Y (NPY) and NPY-related peptides fine-tune the activity of these cells through a receptor specific mechanism. The present study investigated the age-dependent potential of peptide YY (PYY) to modulate different granulocyte functions. The PYY reduced the carrageenan-elicited granulocyte accumulation into the air-pouch of aged (24 months) rats, and markedly decreased the phagocytosis of zymosan, as well as the H(2)O(2) production, when applied in vivo (20 mu g/air-pouch). The anti-inflammatory effect of PYY was less prominent in adult (8 months) and young (3 months) rats. However, the proportions of granulocytes expressing Y1, Y2 and Y5 receptor subtypes were significantly lower in both aged and young rats when compared to adult rats. Furthermore, the aging was found to be associated with the diminished dipeptidyl peptidase 4 (DP4, an enzyme converting the NPY and PYY to Y2/Y5 receptor selective agonists) activity in plasma. In conclusion, the diverse age-related anti-inflammatory effect of PYY in rats originates from different expression levels of Y1, Y2, and Y5 receptor subtypes in addition to different plasma DP4 activity.

AB  - The importance of commensal bacteria in the immune system development and its involvement in the etiopatogenetic mechanisms of complex multifactorial and multigenic diseases is well documented. The aim of the present study was to compare the levels of hydrogen peroxide (H2O2) and nitric oxide (NO) produced by resident peritoneal macrophages from the autoimmune disease susceptible Dark Agouti (DA) rats vs. resistant Albino Oxford (AO) rat strain, under basal conditions and subsequent to in vitro stimulation with gut commensals. Following the stimulation with phorbol myristil acetate (PMA), E. coli/PMA or P. mirabilis/PMA, AO rats macrophages have produced significantly higher levels of H2O2 compared to the cells from DA rats. Strain differences in NO production were not detected under basal conditions and after the stimulation with lipopolysaccharide and P. mirabilis. However, after the in vitro stimulation with E. coli, AO rats macrophages have produced higher levels of NO compared to DA rats macrophages. Our results demonstrated that macrophages from AO rats have higher potential to produce H2O2 and NO in response to specific commensal bacteria when compared to DA rats. A possible relationship between the macrophage activity in response to commensal bacteria and the susceptibility to induction of autoimmune/inflammatory diseases in AO and DA rat strains is suggested.

AB  - Neuropeptide Y (NPY)-induced modulation of the immune and inflammatory responses is regulated by tissue-specific expression of different receptor subtypes (Y1-Y6) and the activity of the enzyme dipeptidyl peptidase 4 (DP4, CD26) which terminates the action of NPY on Y1 receptor subtype. The present study investigated the age-dependent effect of NPY on inflammatory paw edema and macrophage nitric oxide production in Dark Agouti rats exhibiting a high-plasma DP4 activity, as acknowledged earlier. The results showed that NPY suppressed paw edema in adult and aged, but not in young rats. Furthermore, plasma DP4 activity decreased, while macrophage DP4 activity, as well as macrophage CD26 expression increased with aging. The use of NPY-related peptides and Y receptor-specific antagonists revealed that anti-inflammatory effect of NPY is mediated via Y1 and Y5 receptors. NPY-induced suppression of paw edema in young rats following inhibition of DP4 additionally emphasized the role for Y1 receptor in the anti-inflammatory action of NPY. In contrast to the in vivo situation, NPY stimulated macrophage nitric oxide production in vitro only in young rats, and this effect was mediated via Y1 and Y2 receptors. It can be concluded that age-dependant modulation of inflammatory reactions by NPY is determined by plasma, but not macrophage DP4 activity at different ages. (c) 2008 Elsevier Inc.

AB  - We investigated the involvement of specific types of opioid receptors in methionine-enkephalin (MET)-induced modulation of hydrogen peroxide (H2O2) release by rat macrophages primed with sub-optimal concentrations of phorbol myristate acetate (PMA). Peritoneal macrophages in vitro treated with different concentrations of MET were tested for H2O2 release in phenol red assay. In the antagonistic study macrophages were treated with MET and one opioid receptor antagonist, or combination of MET and two or three opioid receptor antagonists. MET decreased H2O2 release in eight individual macrophage samples, and increased it in 10 samples. The increase of H2O2 release induced by MET in macrophages was blocked with combination of opioid receptor antagonists specific delta(1,2) and mu receptors, as well as with combination of antagonists specific for delta(1,2) and kappa opioid receptors. MET-induced decrease of the H2O2 release in macrophages was prevented by opioid receptor antagonists specific for delta(1,2) or mu receptors, and also with combination of two or three opioid receptor antagonists. MET-induced enhancement of H2O2 release was mediated via delta(1) or delta(2) opioid receptor subtypes, or by mu-kappa opioid receptor functional interactions, while MET-induced suppression involved functional interactions between delta(1) and mu, delta(2) and mu, or delta(1) and kappa opioid receptors. It is possible that individual differences in basal or induced macrophage capacity to produce H2O2 might shape the repertoire of opioid receptors expression and in that way pre-determine the direction of MET-induced changes after the in vitro treatment.

AB  - Background: Given that stressful experiences can change the reaction to a subsequent exposure to stress, we tested the in vitro effects of the stress mediator corticosterone and the opioid peptide beta-endorphin on the function of macrophages isolated from control rats and from rats exposed to electric tail shock stress (ES) or a stress-witnessing procedure (SW) 24 h earlier. Methods: Peritoneal macrophages isolated from control and stressed rats of the Dark Agouti (DA) strain were treated in vitro with corticosterone or beta-endorphin and tested for adherence, phagocytosis and hydrogen peroxide release. Results: ES diminished adherence and SW decreased phagocytosis. The suppressive effect of corticosterone on phagocytosis was absent in rats exposed to ES and SW, while the suppressive effect of beta-endorphin on adherence was not observed in rats exposed to SW. ES and SW did not affect H2O2 release, neither directly nor indirectly by changing macrophage response to corticosterone and beta-endorphin in this test. Conclusions: In DA rats early macrophage activation steps, i.e. adherence and phagocytosis, were more sensitive to stress than their effector function, corresponding to H2O2 production. We suggest that neuroendocrine mediators of stress that converge on macrophages might have changed specific macrophage receptors or postreceptor events and alter their response to artificial stressors, represented by corticosterone and beta-endorphin in vitro.

AB  - The aim of our current study was to investigate the effect of acute exposure to electric tail shock stress (ES) and to a stress witnessing procedure (SW), as models for physical and psychological stress paradigms, respectively, on phagocytosis and H2O2 production in peritoneal macrophages isolated from Albino Oxford (AO) and Dark Agouti (DA) rats. In addition, we studied the in vitro effects of methionine-enkephalin (ME) on phagocytosis and H2O2 production in peritoneal macrophages isolated from both AO and DA rats that had been exposed to ES and SW procedures. The results showed that peritoneal macrophages isolated from DA rats were less sensitive to the suppressive effects of ES and SW than macrophages isolated from AO rats. In vitro treatment of macrophages isolated from AO rats with ME mimicked to some extent the suppressive effects of ES and SW on phagocytosis and H2O2 production and additionally diminished H2O2 release in macrophages isolated from AO rats previously exposed to ES or SW ME did not have any effect on phagocytosis in macrophages isolated from DA rats, but changed H2O2 production in a concentration-dependent manner. In macrophages isolated from DA rats previously exposed to stress the effect of ME was dependent on the macrophage function tested and the particular stress paradigm employed. Our results emphasise the fact that both beneficial and detrimental effects of stress on immune system functions could be attributed to the individual variations in the macrophage's response to stress mediators.

AB  - There is extensive evidence for the critical role of reactive oxygen species (ROS) and nitric oxide (NO) produced by phagocytes in development of inflammatory processes and pathogenesis of numerous diseases, including rheumatoid arthritis (RA). Apart from their function as mediators of inflammation and tissue damage, recent research supports their role as signaling and regulatory molecules. In the present study we have investigated the production of ROS and NO over the course of adjuvant arthritis (AA) and oil-induced arthritis (OIA), by resident peritoneal macrophages of two rat strains: Dark Agouti (DA), susceptible, and Albino Oxford (AO), resistant to induction of AA and OIA. We have compared levels of ROS and NO produced by susceptible vs. resistant rat strain, and investigated their relevancy for arthritis development and severity. In addition, we have stimulated macrophages in vitro with Mycobacterium bovis BCG, and two heat shock proteins (HSP): endogenous HSP47 and mycobacterial HSP71 (rnHSP71). Our results suggest a possible contribution of increased ROS production to arthritis resistance of AO rats. The ROS production in AO rats is potentiated by endogenous HSP47, but not with mycobacterial cell and mHSP71, suggesting HSP47 participates in AA control. We have found no fundamental relationship between the magnitude of NO production and AA and OIA susceptibility and severity, suggesting that NO has no effector role in AA and OIA. Our results advocate a regulatory type action of NO molecule aught be more significant in arthritis development. (c) 2006 Elsevier GmbH. All rights reserved.

Our results suggest a possible contribution of increased ROS production to arthritis resistance of AO rats. The ROS production in AO rats is potentiated by endogenous HSP47, but not with mycobacterial cell and mHSP71, suggesting HSP47 participates in AA control. We have found no fundamental relationship between the magnitude of NO production and AA and OIA susceptibility and severity, suggesting that NO has no effector role in AA and OIA. Our results advocate a regulatory type action of NO molecule aught be more significant in arthritis development. (c) 2006 Elsevier GmbH. All rights reserved.",

AB  - The objective of the present study was to investigate the effect of acute exposure to electric tail shock stress (ES) and a stress witnessing procedure ( SW), as models for physical and psychological stress paradigms, respectively on adherence, phagocytosis and hydrogen peroxide (H2O2) release from rat peritoneal macrophages. In addition, we studied the in vitro effects of corticosterone (CORT), neuropeptide Y (NPY) and beta-endorphin (BE) on adherence, phagocytosis and H2O2 release from macrophages isolated from control rats and from rats that had been exposed to ES or SW procedures 24 h earlier. ES and SW comparably diminished phagocytosis and H2O2 release, but did not influence macrophage adherence. In vitro treatment with CORT and NPY notably suppressed phagocytosis and potentiated H2O2 release from macrophages. BE suppressed both phagocytosis and H2O2 release from macrophages. Previous exposure to ES and SW altered the responsiveness of the isolated macrophages to their in vitro treatment with mediators of stress, making the cells less sensitive to the influence of CORT and NPY and to a lesser extent to BE. It could be concluded that changes in the local macrophage milieu induced by ES and SW 24 h earlier modify macrophage responses to subsequent in vitro exposure to the stress mimics, CORT, NPY and BE.
