AB  - S1.1. Checking of N protein purity Recombinant N protein purity was checked after imidazole removal and buffer exchange by SDS PAGE (Figure 6.). For comparison, commercial high-purity HSA was also analyzed. S1.2. Identification of N protein Tandem mass spectrometry identification of proteins in an in-gel digested band of N protein (Figure S1, lane 3), confirmed the identity of N protein with high scores and peptide coverage (Fig. S2.). S2. Purification of polyclonal antibodies from mice and rabbit sera For the development of an ELISA test specific for the detection of SARS-CoV-2 N protein, recombinantly produced N protein was used for the immunization of mice and rabbits. Sera obtained from rabbits and mice were then tested for titer and specificity (Figure S3 and Figure 1). To determine the titer of polyclonal sera required to detect N protein in samples, we use wells coated with N protein and serial dilution of sera pools from different animals. After multiple washing steps, we detected the binding of rabbit and mice antibodies using secondary biotinylated antibodies and streptavidin-alkaline phosphatase chimaera or secondary antibodies with previously coupled alkaline phosphatase, where the amount of enzymes’ substrate converted to the product was measured as an increase in absorbance at 405 nm. As shown in Figure S3A, unpurified sera pools from both animals showed very high titers and expected logarithmic decrease of signal with dilution. Based on the obtained data titer for unpurified sera was determined to be X. The same trend was observed for pools purified using AS precipitation and rabbit sera purified using protein A affinity chromatography (Figure S3B and S3C). As shown in Figure S3D, clear bands from antibodies could be observed in both full and purified samples. Western blot analysis showed only one protein band on mass around 40 kDa, a Accession number / Protein Name Score Coverage (%) Unique peptides P0DTC9|NCAP_SARS2 Nucleoprotein OS=Severe acute respiratory syndrome coronavirus 2, 46 kDa 504.9 74.22 183 mass of purified N protein suggesting that the obtained sera is highly specific for N protein (Figure 2). Section S3 Diagnostic validationS3.1. Stabilization of capture antibodies Pre-coated ELISA plates were prepared for usage in clinical practice. To ensure the preservation of the biofunctionality of the surface-bound capture antibodies, the commonly used stabilizing excipient, 3% sucrose with 10% glycerol in MilliQ water was used. The plates were incubated with 300 μL per well of a stabilizing agent for 1 hour at room temperature. After an hour of incubation, the solution was carefully aspirated from each well. The plate was then blotted against clear paper towels to remove any remaining liquid, and the plates were allowed to air dry for 3 hours at RT. Dried plates were wrapped in parafilm and stored at 4 °C for later use. To remove the stabilizing agent coating, wells were washed with slightly acidic distilled water (pH of 6) three times, leaving the plate prepared for subsequent assay steps. Section S4. Characterization of N protein by HRMS S4.1. SDS PAGE and in-gel digestion Characterization of the produced recombinant N protein was done by HRMS after its in-gel digestion. A total of 10 μg of purified protein(s) were loaded in a 0.5 cm wide well and after SDSPAGE gel was stained with Coomassie Brilliant Blue R-250 (CBB). Protein gel bands were washed, reduced with dithiothreitol, and alkylated with iodoacetamide, followed by in-gel trypsin digestion1 (Shevchenko et al. 2006) with some minor modifications. The amount of trypsin was leveled to a trypsin/sample ratio of 1:30 (w/w). The final concentration of MS-grade trypsin (diluted in 25 mM ammonium bicarbonate buffer) was 1 ng/μL. Sample clean-up was performed using zip tips HyperSep C18 (Thermo Fisher Scientific Inc., Bremen, Germany). S5.1 Immunization of rabbits and mice Mice immunization Swiss Webster mice (n=10) were immunized subcutaneously with N protein formulated with Complete Freund`s adjuvant (CFA; 1st dose, 100 μg N protein / dose) or Incomplete Freund`s adjuvant (IFA; 2nd and 3rd doses, 50 μg N protein / dose) in three-week intervals. Mice were housed in small groups of up to six animals and had access to commercial mice food and water ad libitum. N protein solution (500ug/ml in PBS) was sterilized by filtering through 0.22 um filters. Sterile N protein solution was mixed with CFA (Sigma, Cat. No. F5881) at ratio 1:1 (v/v) under aseptic conditions. In total 400 ul of N protein-CFA emulsion (N protein final concentration 250ug/ml) was applied per immunization per mouse. Initial immunization was done by injection of N protein in CFA given subcutaneously (SC) in four sites (thigh pocket, base of tail, and mediastinum) with a 100 ul using 23-25 gauge needle. In total 100 ug of N protein was applied per mouse (25 ug per site). Subsequent immunizations with booster doses were done in the same way, but using IFA (Sigma, Cat. No. F5506) instead of CFA and N protein final concentration was 125 ug/ml. . In total 50 ug of N protein was applied per mouse (12.5 ug per site). Immunizations were done every three weeks. Mice immunization scheme: 1. day 0 – N protein in PBS: CFA = 1:1 (v/v); N protein final concentration was 250 μg/mL; 400 μL per mice (4x100 μL), e.g. 100 μg per mice 2. day 21 - N protein in PBS: IFA = 1:1 (v/v); N protein final concentration was 125 μg/mL; 400 μL per mice (4x100 μL), e.g. 50 μg per mice 3. day 42 - N protein in PBS: IFA = 1:1 (v/v); N protein final concentration was 125 μg/mL; 400 μl per mice (4x100 μL), e.g. 50 μg per mice First bleeding was performed two weeks after the 3rd dose, and then in intervals not shorter than two weeks. The sera obtained after the first bleeding was tested for the production of specific anti-N protein antibodies.

AB  - In this study, a cost-effective sandwich ELISA test, based on polyclonal antibodies, for routine quantification SARS-CoV-2 nucleocapsid (N) protein was developed. The recombinant N protein was produced and used for the production of mice and rabbit antisera. Polyclonal N protein-specific antibodies served as capture and detection antibodies. The prototype ELISA has LOD 0.93 ng/mL and LOQ 5.3 ng/mL, with a linear range of 1.52–48.83 ng/mL. N protein heat pretreatment (56 °C, 1 h) decreased, while pretreatment with 1% Triton X-100 increased analytical ELISA sensitivity. The diagnostic specificity of ELISA was 100% (95% CI, 91.19–100.00%) and sensitivity was 52.94% (95% CI, 35.13–70.22%) compared to rtRT-PCR (Ct < 40). Profoundly higher sensitivity was obtained using patient samples mostly containing Wuhan-similar variants (Wuhan, alpha, and delta), 62.50% (95% CI, 40.59 to 81.20%), in comparison to samples mostly containing Wuhan-distant variants (Omicron) 30.00% (6.67–65.25%). The developed product has relatively high diagnostic sensitivity in relation to its analytical sensitivity due to the usage of polyclonal antibodies from two species, providing a wide repertoire of antibodies against multiple N protein epitopes. Moreover, the fast, simple, and inexpensive production of polyclonal antibodies, as the most expensive assay components, would result in affordable antigen tests.

AB  - Novi korona virus (SARS CoV-2) koji se pojavio u Vuhanu 2019. godine pripada grupi jednolančanih RNK virusa [1]. Predstavlja novi infektivni agens za humanu populaciju i veoma je brzo detektovan u velikom broju zemalja. Uzročnik je respiratornih infekcija koje mogu da budu praćene i veoma teškom kliničkom slikom. Brzo širenje, odsustvo imuniteta na ovaj virus i odsustvo pouzdanih testova za detekciju virusa u trenutku izbijanja pandemije su bolest izazvanu ovim virusom brzo pretvorili u zdravstveni i društveni problem najvišeg prioriteta na globalnom nivou. Iako su najveće biotehnološke kompanije ubrzano počele sa razvojem i masovnom proizvodnjom dijagnostičkih testova i vakcina, njihova dostupnost u trenucima najveće potražnje je i dalje nedovoljna, a cene istih su limitirajući faktor za bolju kontrolu bolesti i širenja pandemije [2]. Razvoj sopstvenih i održiva proizvodnja testova i vakcina za COVID-19 su od velikog društvenog značaja.

AB  - BACKGROUND Deregulation of the immune response to microbiota or pathogens, and increased intestinal permeability have been proposed as disease-driving mechanisms in colitis. Since peritoneal macrophages guard the sterility of peritoneal cavity from bacterial leakage from the gut, it is plausible to assume that peritoneal macrophages are involved in colitis development. OBJECTIVES The objective was to investigate changes in the composition of peritoneal cells and their response to stimulation by selected gut microbiota during colitis. METHODS Seven days following induction of colitis with intrarectal instillation of ethanol or trinitrobenzenesulfonic acid (TNBS, 10mg/kg or 40mg/kg), peritoneal cells of Dark Agouti (DA) rats were isolated and subjected to flow cytometry. The amount of IL-6 and TNF-α produced by adherent cells was determined by ELISA following in vitro stimulation with LPS and commensal E.coli and Enteroccocus spp.
RESULTS
Instillation of ethanol or TNBS (10 and 40 mg/kg) increased the proportion of CD11bintCD4low monocytes
and decreased the proportion of resident CD163+MHCIIIo macrophages and CD163-MHCIIhi macrophage/dendritic cells.
In vitro treatment with Enterococcus spp. was superior over LPS and E.coli in increasing macrophage TNF-α release in all
but saline-injected control rats. In vitro treatment with E.coli exceeded the level of LPS stimulation in
inducing macrophage IL-6 release in saline- and ethanol-injected rats. It may be concluded that changes in the
composition of peritoneal cells during colitis and, subsequently, their selectively altered response to gut commensals
may perpetuate or modulate inflammation during disease development

AB  - BACKGROUND A variety of commensal bacterial taxa elicit serum IgA responses resulting in protection against polymicrobial sepsis, whereas anti-commensal IgG may have deleterious role in gastrointestinal and systemic inflammation. OBJECTIVES The aim was to determine the systemic levels of specific antibodies directed to autologous E.coli in rats of Albino Oxford (AO) and Dark Agouti (DA) rat strains during colitis. METHODS Rats were intrarectally injected with ethanol or trinitrobenzenesulfonic acid (TNBS, 10 or 40mg/kg) whereas controls received saline in the same manner. Sera were tested for the level of anti-E.coli antibodies of IgG1, IgG2a, IgG2b and IgA classes by ELISA. RESULTS Both rat strains developed colitis, but the degree of colon necrosis and hyperemia were slightly greater in DA than in AO rats and the survival rate was significantly lower in DA relative to AO rats. Among saline-treated controls, the levels of IgG1, IgG2a, and IgG2b anti-E.coli antibodies were comparable between rat strains, whereas the amounts of IgA were significantly higher in DA compared to AO rats. Development of colitis significantly increased the amount of anti-E.coli antibodies of IgA and IgG2a classes in sera of AO rats, and those of IgG2a and IgG2b classes in sera of DA rats. Hence, mostly beneficial role of IgA and probably deleterious role of IgG2b antibodies directed to commensal E.coli during colitis may be suggested, whereas the role of anti-E.coli antibodies of IgG2a classes remains intriguing.

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 current study investigated a potential modulating effect of orally applied Lactobacillus rhamnosus 64 (LB64) during the early postnatal period (day of life: similar to 3-30), during young adult period (day of life: 31-70) or throughout experiment, on parameters of trinitrobenzenesulfonic acid (TNBS)-induced colitis in adult rats. Treatment with LB64 during early postnatal, but not during young adult period reduced clinical damage score, neutrophil and macrophage infiltration into colon, the level of cytokine and myeloperoxidase (MPO) activity, but had no influence on other parameters of oxidative damage. Early postnatal treatment with LB64 also increased the diversity of fecal Bifidobacteria and Eubacteria, and improved maturation of ileal villi in 30-days old rats. When LB64 is applied during a critical period early in life, it affects immune system functioning of adults, probably by interactions with the mucosal immune system of the gastrointestinal tract that provides immune system maturation and shapes the overall immune response.

AB  - smanjena imunološka funkcija kod žena u menopauzi je uglavnom posledica nedostatka hormona ovarijuma u cirkulaciji. Supstituciona hormonska terapija najčešće podrazumeva nadoknadu estrogena, ali ne i progesterona. U ovom radu kao eksperimantalni model izolovane deficijencije progesterona korišćeni su pacovi stari 20 meseci ovarijektomisani na kraju reproduktivnog preioda (starosti 10 meseci) kod kojih je koncentracija estradiola (usled ekstragonadne sinteze) u nivou estradiola kod lažno ovarijektomisanih pacova iste starosti. Ispitivane je intraćelijska ekspresija receptora za estrogene (ER) i progesteron (PR) i sekrecija pro- i anti-inflamatornih citokina i krajnjih produkata metabolizma arginina u slezinskim i peritonealnim makrofagama, u bazalnim uslovima i nakon in vitro stimulacije sa lipopolisaharidom (LPS). Pokazano je da i peritonealne i slezinske makrofage ispoljavaju ER alfa i ER beta, kao i da ovarijektomija ne utiče na ekspresiju ER-a. Većina peritonealnih i slezinskih makrofaga je ispoljavala PR, a ovarijektomija je dovela do povećanja ekspresije PR samo u slezinskim makrofagama. Ovrijektomija je smanjila i sekreciju citokina iz slezinskih (IL-1beta) i peritonealnih makrofaga (TNF-alfa, IL-1beta, IL-10) i povećala sekreciju IL-10 iz slezinskih i TGF-beta iz peritonealnih makrofaga u bazalnim uslovima. Nakon stimulacije LPS-om, slezinske makrofage  ovarijektomisanih pacova su sekretovale manje TNF-alfa i više IL-10, dok su peritonealne makrofage sekretovale manje IL-1beta i TGF-beta nego ćelije istog porekla iz lažno-ovarijektomisanih pacova. Ovarijektomija je smanjila sintezu uree i u slezinskim i u peritonealnim makrofagama stimulisanim LPS-om. Dugotrajna izolovana deficijencija progesterona u post-reproduktivnom periodu narušava ravnotežu u produkciji pro-/anti-inflamatornih citokina slezinskih i peritonealnih makrofaga.

AB  - Between December 2010 and August 2011 an outbreak of measles occurred in Serbia with 363 reported cases. Sera and/or nose/throat swabs were collected from 193 patients and tested for measles-specific IgM antibodies by ELISA and viral RNA by RT-PCR, respectively. Epidemiological data were obtained from the surveillance database of the Institute of Public Health of Serbia. Of the 363 cases involved in the outbreak, 113 were laboratory confirmed. More than one third of the patients were hospitalized (n = 130, 35.8%) and for 15 (4.1% of the reported outbreak cases) the infection was complicated by pneumonia. Mostly pre-school children aged  lt = 4 years (37.8%) and adults aged  gt = 30 years (27.3%) were affected. The majority of patients belonged to the Roma population with a preponderance of female cases (57.0%). Nearly 94% of the patients were either unvaccinated or of unknown vaccination status. The main outbreak virus was the D4-Hamburg strain. The outbreak in Serbia occurred after several years of very low measles incidence despite a high routine immunization coverage in the general population, suggesting that special efforts to identify and vaccinate susceptible population groups are required even in countries with apparently good disease control.

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.

AB  - Trachoma, caused by the intracellular bacterium Chlamydia trachomatis (Ct), remains the world's leading preventable infectious cause of blindness. Recent attempts to develop effective vaccines rely on modified chlamydial antigen delivery platforms. As the mechanisms engaged in the pathology of the disease are not fully understood, designing a subunit vaccine specific to chlamydial antigens could improve safety for human use. We propose the delivery of chlamydia-specific antigens to the ocular mucosa using particulate carriers, bacterial ghosts (BGs). We therefore characterized humoral and cellular immune responses after conjunctival and subcutaneous immunization with a N-terminal portion (amino acid 1-893) of the chlamydial polymorphic membrane protein C (PmpC) of Ct serovar B, expressed in probiotic Escherichia coli Nissle 1917 bacterial ghosts (EcN BGs) in BALB/cmice. Three immunizations were performed at two-week intervals, and the immune responses were evaluated two weeks after the final immunization in mice. In a guinea pig model of ocular infection animals were immunized in the same manner as the mice, and protection against challenge was assessed two weeks after the last immunization. N-PmpC was successfully expressed within BGs and delivery to the ocularmucosa was well tolerated without signs of inflammation. N-PmpC- specific mucosal IgA levels in tears yielded significantly increased levels in the group immunized via the conjunctiva compared with the subcutaneously immunized mice. Immunization with N-PmpC EcN BGs via both immunization routes prompted the establishment of an N-PmpC-specific IFN gamma immune response. Immunization via the conjunctiva resulted in a decrease in intensity of the transitional inflammatory reaction in conjunctiva of challenged guinea pigs compared with subcutaneously and non-immunized animals. The delivery of the chlamydial subunit vaccine to the ocular mucosa using a particulate carrier, such as BGs, induced both humoral and cellular immune responses. Further investigations are needed to improve the immunization scheme and dosage.

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.

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  - In 2012, mumps was introduced from Bosnia and Herzegovina to Vojvodina, causing an outbreak with 335 reported cases. The present manuscript analyses the epidemiological and laboratory characteristics of this outbreak, identifies its main causes and suggests potential future preventive measures. Sera of 133 patients were tested for mumps-specific antibodies by ELISA and 15 nose/throat swabs were investigated for mumps virus RNA by RT-PCR. IgG antibodies were found in 127 patients (95.5%). Mumps infection was laboratory-confirmed in 53 patients, including 44 IgM and 9 PCR positive cases. All other 282 cases were classified as epidemiologically-confirmed. More than half of the patients (n = 181, 54%) were 20-29 years old, followed by the 15-19 age bracket (n = 95, 28.4%). Twice as many males as females were affected (67% versus 33%). Disease complications were reported in 13 cases (3.9%), including 9 patients with orchitis and 4 with pancreatitis. According to medical records or anamnestic data, 190 patients (56.7%) were immunized with two doses and 35 (10.4%) with one dose of mumps-containing vaccine. The Serbian sequences corresponded to a minor genotype G variant detected during the 2011/2012 mumps outbreak in Bosnia and Herzegovina. Vaccine failures, the initial one-dose immunization policy and a vaccine shortage between 1999 and 2002 contributed to the outbreak. Additional vaccination opportunities should be offered to young adults during transition periods in their life trajectories.

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  - 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.

Rezidentne peritonealne ćelije su ispitivane metodom protočne citofluorometrije, a zatim je nakon adherence testirana njihova sposobnost fagocitoze čestica zimozana i kapacitet produkcije vodonik peroksida (H2O2) i azot monoksida (NO). U neimunizovanih pacova makrofage DA soja su intenzivnije fagocitovale čestice zimozana i imale nižu sposobnost produkcije H2O2 nego ćelije pacova AO soja, ali nije bilo sojnih razlika u sposobnosti produkcije NO. Imunizacija je dovela do povećanja fagocitne sposobnosti makrofaga DA pacova, ali i do smanjenja fagocitoze i produkcije H2O2 makrofaga pacova AO soja. Generalno veću sposobnost fagocitoze u DA pacova prati i značajno veća zastupljenost ED1+ ćelija (koje čine uglavnom makrofage i dendritične ćelije) nasuprot većoj zastupljenosti ED2 antigena (marker rezidentnih makrofaga) na ćelijama pacova AO soja.

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  - 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  - 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  - 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  - 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  - 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 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.
