AB  - The Institute of Virology, Vaccines and Sera Torlak was established in 1927, while the first vaccine was produced in the Institute in 1930. Vaccines production implies using experimental animals, including mice, in in-process controls. The laboratory mice which have been in use in Torlak Institute from the very beginning belong to Swiss albino outbred stock. This stock, which has been in use for more than 80 years contains a large number of mice maintained at all times, was recently named Intor:Swiss. Biological characteristics of Intor:Swiss stock, are presented in this paper for the first time. Taking into account the presented characteristics, the Institute Torlak's Swiss mice are suitable for use in pharmaceutical studies, vaccine development research and basic research, as well as in toxicological studies. The publication of data on the Intor:Swiss mice represents a contribution to the international scientific community, since it offers the possibility for obtaining an additional outbred mouse stock for research.
AB  - Institut za Virusologiju, vakcine i serume Torlak, osnovan je 1927., a prva vakcina u Institutu proizvedena je 1930. Proizvodnja vakcina je složen proces koji između ostalog podrazumeva i korišćenje eksperimentalnih životinja u kontroli samog procesa. Laboratorijski miševi koji su od samog početka bili u upotrebi u Institutu Torlak, pripadaju Swiss albino outbred soju. Ova kolonija je u upotrebi više od 80 godina i sve vreme se sastoji od velikog broja jedinki što omogućava očuvanje genetske raznolikosti, pa samim tim i outbred karakteristika. Ovi miševi su odnedavno registrovani pod imenom Intor:Swiss, i njihove biološke osobine su u ovom radu prikazane po prvi put. Swiss miševi Instituta Torlak pogodni su za upotrebu u farmaceutskim studijama, za razvojno istraživanje vakcina, osnovna istraživanja i toksikološka ispitivanja. Zbog svega navedenog Intor:Swiss miševi predstavljaju još jedan pogodan animalni model za ispitivanje lekova i vakcina.

AB  - Testing of every new vaccine involves investigation of its immunogenicity, which is based on monitoring its ability to induce specific antibodies in animals. The fastest and most sensitive method used for this purpose is enzyme-linked immunosorbent assay (ELISA). However, commercial ELISA kits with whole influenza virus antigens are not available on the market, and it is therefore essential to establish an adequate assay for testing influenza virus-specific antibodies. We developed ELISA with whole influenza virus strains for the season 2011/2012 as antigens and validated it by checking its specificity, accuracy, linearity, range, precision, and sensitivity. The results show that we developed high-quality ELISA that can be used to test immunogenicity of newly produced seasonal or pandemic vaccines in mice. The pre-existence of validated ELISA enables shortening the time from the process of vaccine production to its use in patients, which is particularly important in the case of a pandemic.

AB  - This study investigated a putative contribution of mast cells and C-sensory fibers to differences in the development of inflammatory edema following the injection of concanavalin A (Con A) into the hind paws of Dark Agouti (DA) and Albino Oxford (AO) rats. 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  - We have investigated the humoral immune response to antigens of predominant gut aerobic bacterial strains (i.e. Escherichia coli) over the course of adjuvant arthritis and oil-induced arthritis in two inbred rat strains: Dark Agouti (DA) and Albino Oxford (AO). We report the presence of antibodies specific to proteins of Escherichia coli in molecular weight range between 20-30 kDa in sera of diseased DA rats, and the absence of these antibodies in the sera of AO rats. In DA rats, CFA and IFA provoked a stronger antibody response to Escherichia coli, especially of the IgG2b antibody class. Intramuscular administration of Escherichia coli preceding the adjuvant arthritis induction had no effect on the development and course of disease, as well as on the activation of T cells in the draining inguinal lymph nodes. Higher serum levels of natural and induced IgA antibodies, combined with a higher CD3(+)CD26(+) cell percentage were found in AO rats. The observed correlation between the serologic response to commensal flora and rats' genetic background as a defining factor for arthritis susceptibility may contribute to the process of creating a favorable (or less favorable) milieu for arthritis development.

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  - We have investigated the immune response to commensal bacterial species in the two inbred rat strains: Dark Agouti (DA) and Albino Oxford (AO). The predominant Gram-negative aerobe in our rats' intestinal bacterial flora was Escherichia coli, while Proteus mirabilis was isolated only from DA rat strain. We report that sera from both DA and AO rat strains contain specific IgG against predominant intestinal flora. Intramuscular administration of commensal bacterial antigens provoked only Th1-type antibody response in AO rats while DA rats developed mixed Th1- and Th2-type antibody response to E. coli and Th1-type response to P. mirabilis antigens. Weaker antibody production to own E. coli and higher serum levels of natural IgG and IgA P. mirabilis-specific antibodies combined with higher CD3+ cells proliferation was found in AO rats. Strain difference in the pattern of antibody production and differential regulation of immune response to commensal bacteria may contribute to the marked differences in the immune reactivity of AO and DA rats.

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.

abstract = "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., 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  - We have investigated the phenotype of peritoneal cells and the functions of peritoneal macrophages obtained from experimental autoimmune encephalomyelitis (EAE)-susceptible Dark Agouti (DA) and EAE-resistant Albino Oxford (AO) rat strains on days 1, 3 and 7 post immunization with encephalitogen. Resident peritoneal cells from immunized and non-immunized rats of both strains were subjected to flow cytometric analyzes and after adherence were tested for zymosan phagocytosis, hydrogen peroxide (H2O2) and nitric oxide (NO) production. In non-immunized rats, macrophages from the DA rat strain phagocytosed more zymosan but produced less H2O2 than cells from the AO strain, while both strains produced comparable amounts of NO. Immunization increased phagocytosis in DA rats' cells, but decreased both phagocytosis and H2O2 production in cells from AO rats. Overall higher phagocyte ability in DA rats was associated with a significantly larger population of ED1+ cells (macrophages and dendritic cells), in contrast to a more pronounced expression of ED2 antigen (resident macrophages) on cells from AO rats. Immunization also increased the expression of CD11b molecule on non-resident ED2-macrophages of DA, but not of AO rats. The early and subtle phenotype changes in peritoneal cells of both rat strains might mirror the mechanism contributing to their different sensitivity to the induction of autoimmunity.

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  - Poznato je da komensalna crevna flora ima značajnu ulogu u razvoju imunskog sistema kao i u etiopatogenezi kompleksnih multifaktorijalnih i multigenetskih bolesti. Cilj ovog rada bio je da se uporedi produkcija vodonik peroksida (H2O2) i azot monoksida (NO) peritonealnih makrofaga dva inbredna soja pacova, od kojih je jedan osetljiv (Dark Agouti, DA), a drugi rezistentan (Albino Oxford, AO) na indukciju autoimunskih bolesti, kako u bazalnim uslovima tako i nakon in vitro stimulacije makrofaga sa crevnim komensalima. Nakon stimulacije sa forbol miristil acetatom (PMA), E. coli/PMA and P. mirabilis/PMA makrofage AO pacova su produkovale značajno više H2O2 u poređenju sa makrofagama DA pacova.

abstract = "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., Poznato je da komensalna crevna flora ima značajnu ulogu u razvoju imunskog sistema kao i u etiopatogenezi kompleksnih multifaktorijalnih i multigenetskih bolesti. Cilj ovog rada bio je da se uporedi produkcija vodonik peroksida (H2O2) i azot monoksida (NO) peritonealnih makrofaga dva inbredna soja pacova, od kojih je jedan osetljiv (Dark Agouti, DA), a drugi rezistentan (Albino Oxford, AO) na indukciju autoimunskih bolesti, kako u bazalnim uslovima tako i nakon in vitro stimulacije makrofaga sa crevnim komensalima. Nakon stimulacije sa forbol miristil acetatom (PMA), E. coli/PMA and P. mirabilis/PMA makrofage AO pacova su produkovale značajno više H2O2 u poređenju sa makrofagama DA pacova. Nisu detektovane sojne razlike u produkciji NO u bazalnim uslovima, kao ni posle stimulacije sa lipopolisaharidom i P. mirabilis.

AB  - Using both immunocytochemical and flow cytometric analyses of rat peritoneal exudate cells constitutive expression of tyrosine hydroxylase and both beta(2)- and alpha(1)-adrenoceptors on macrophages was revealed. Furthermore, according to the characteristic assemblage of tyrosine hydroxylase and adrenoceptor subtype expression different macrophage subsets were identified. In vitro treatment of macrophages with the nonselective alpha,beta-adrenoceptor agonist arterenol and/or the beta-adrenoceptor antagonist propranolol indicated that beta-adrenoceptors potentiated nitric oxide (NO) production and suggested alpha-adrenoceptor-mediated suppression of hydrogen peroxide (H2O2) production. An increase in H2O2 production in the presence of the alpha(1)-adrenoceptor antagonist ebrantil provided support for this. Chronic propranolol treatment in vivo led to increased NO and H2O2 production by peritoneal macrophages. Furthermore, this treatment resulted in opposing effects on the expression Of beta(2)- and alpha(1)-adrenoceptors on peritoneal macrophages (a stimulatory effect on beta(2)-adrenoceptors and a suppressive effect on alpha(1)-adrenoceptors). In conclusion, a subset of resident peritoneal macrophages synthesizes catecholamines, which may exert differential effects on H2O2 and NO production via distinct adrenoceptors. Finally, chronic propranolol treatment affected adrenoceptor expression on peritoneal macrophages and altered their capacity to generate NO and H2O2. (C) 2009 Elsevier B.V. All rights reserved.

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.

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.

AB  - The objective of the present study was to investigate the relevance of peripheral macrophage activity for the susceptibility to the induction of experimental allergic encephalomyelitis (EAE). Rats of EAE-susceptible Dark Agouti and EAEresistant Albino Oxford strain were immunized with guinea pig spinal cord homogenate (DA(GPSC) and AO(GPSC)), while non-immunized rats served as controls (DA(NIM), AO(NIM))- On day 15 after immunization rats were sacrificed and their peritoneal macrophages tested for adherence capacity, zymosan phagocytosis and respiratory burst. Macrophages from AO(NIM) rats exhibited lower adherence capacity and higher phagocytosis and H2O2 production when compared to macrophages from DA(NIM) rats. Immunization with GPSC decreased adherence and phagocytosis and increased H2O2 production in macrophages from AO rats, but did not influence these activities in macrophages from DA rats. The results from the present study suggest that inflammatory activities of macrophages from AO rats could be considered as regulatory mechanisms connected with the resistance to EAE induction.

AB  - It is well documented that neuropeptides participate in local inflammatory reaction and modulate functions of inflammatory cells. The aim of the study was to determine a link between in vivo and in vitro effects of NPY-related peptides on inflammatory response with respect to ageing. Peptide YY (PYY) intraplantarly applied decreases concanavalin A-induced paw edema in 3 and 8 months, but not in 24 months old male rats of Albino Oxford strain. The use of NPY-related receptor-specific peptides and Y1 receptor antagonist revealed that anti-inflammatory effect of PYY is mediated via NPY Y1 receptors. PYY in vitro decreases adherence of macrophages from 8 months, but not from 3 and 24 months old rats and this effect is also mediated via NPY Y1 receptor. Additionally, PYY (10(-6) M) decreases NBT reduction in macrophages from 3 and 8 months old rats, and suppresses NO production in cells from 24 months old rats, albeit regardless of absence of in vivo effect of PYY on inflammation in aged rats. It is concluded that aged rats are less responsive to anti-inflammatory action of PYY compared to adult and young rats, and that ageing is associated with altered NPY Y1 receptor functioning.

AB  - It has been shown that inflammation of rat paws elicits accumulation of opioid peptide is-endorphin-containing immune cells in the inflamed subcutaneous tissue, contributing to immumocyte-produced pain suppression. However, the possible mechanisms involved in the pharmacological application of beta-endorphin in rat paw inflammation have not been investigated. The present study was set up to explore the effects of intraplantar injection of beta-endorphin on Concanavalin A-induced paw edema in two inbred rat strains, Albino Oxford (AO) and Dark Agouti (DA). Both high dose-induced suppression and low dose-induced potentiation of edema development in AO and DA rats, respectively, were blocked with antagonists specific for 6 (naltrindole) and K (nor-binaltorphimine) opioid receptors. beta-endorphin in vitro decreased phagocytosis and increased nitric oxide (NO) production in air pouch granulocytes obtained from AD rats. However, in cells from DA rat strain beta-endorphin modulated both phagocytosis and NO production in a concentration-dependent manner. It could be concluded that the strain-dependent opposing effects of endorphin on paw inflammation are mediated through 6 and K opioid receptors and probably involve changes in the production of reactive oxygen species by inflammatory cells. Our results point to the importance of genotype for pharmacological manipulations and the development of inflammation. (c) 2006 Elsevier B.V. All rights reserved.
