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  - 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.

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.

abstract = "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.
