AB  - The size of circulating immune complexes (CICs) in rheumatoid arthritis (RA) could be an emerging criterion in disease diagnosis. This study analyzed size and electrokinetic potential of CICs from RA patients, healthy young adults, and RA patients age-matched controls aiming to establish their unique CIC features. Pooled CIC of 30 RA patients, 30 young adults, and 30 RA group's age-matched controls (middle-aged and oldеr healthy adults), and in vitro IgG aggregates from pooled sera of 300 healthy volunteers were tested using dynamic light scattering (DLS). Size distribution of CIC in healthy young adults exhibited high polydispersity. RA CIC patients and their age-matched control showed distinctly narrower size distributions compared with young adults. In these groups, particles clustered around two well-defined peaks. Particles of peak 1 were 36.1 ± 6.8 nm in RA age-matched control, and 30.8 ± 4.2 nm in RA patients. Particles of peak 2 of the RA age-matched control's CIC was 251.7 ± 41.2 nm, while RA CIC contained larger particles (359.9 ± 50.5 nm). The lower zeta potential of RA CIC, compared to control, indicated a disease-related decrease in colloidal stability. DLS identified RA-specific, but also age-specific distribution of CIC size and opened possibility of becoming a method for CIC size analysis in IC-mediated diseases.

AB  - U ovom izlaganju biće predstavljeni naši dosadašnji rezultati na temu antimikrobnih antitela kod profesionalnih sportista, odraslih osoba koje se ne bave profesionalno sportom; promene nivoa antibakterijskih antitela pri starenju; poređenje specifičnosti serumskih i salivarnih IgA antitela kod mladih odraslih osoba, kao i nivoi ukupnih i antibakterijskih antitela u Covid-19 virusnoj infekciji i u sepsi. Nivoi i titri antimikrobnih antitela različitih klasa i potklasa određivani su ELISA testom iz uzoraka seruma, plazme ili salive. Ispitivano je vezivanje za izolovane antigene mikroorganizama (lipopolisaharid, peptidoglikan i zimozan) i za cele mikroorganizme, različitih vrsta i sojeva. Vezivanje prečišćenog salivarnog IgA za mikroorganizme praćeno je i protočnom citometrijom. Od rezultata izdvajamo da izlaganje fizičkom naporu visokog intenziteta dovodi do promena na nivou antibakterijskih antitela, i to u pravcu sveobuhvatnijeg prepoznavanja lipopolisaharida1. Suplementacija profesionalnih sportista određenim probioticima dovodi do održanja nivoa ukupnih salivarnih i serumskih IgA antitela, kao i IgG antitela specifičnih prema Enterococcus faecalis, koja su u ovoj populaciji pokazala sezonsku varijaciju. Pri starenju dolazi do smanjenja nivoa antipneumokoknih antitela i to zavisno od pola, pa su stariji mukarci naročito pogođeni ovim smanjenjem3. Salivarna IgA antitela razlikuju se po specifičnosti od serumskih IgA antitela i pružaju nespecifičnu zaštitu. Poređenje pacijenata sa sepsom, hospitalizovanih Covid-19 pacijenta i starosnih kontrola pokazalo je brojne razlike u nivoima kako ukupnih, tako i antibakterijskih antitela. Nivoi antibakterijskih antitela kod pacijentata koji nisu preživeli bili su niži nego kod onih koji su preživeli, što potvrđuje značaj ovih anititela za preživljavanje sepse.

AB  - Background: Recent literature data highlights metabolic changes in amyotrophic lateral sclerosis (ALS). To explore possible early metabolic changes, we aimed to analyse the fatty acids (FA) composition of erythrocytes in newly diagnosed als patients and to see whether fatty acid levels correlate with the ALSFRS-R score or disease duration. Methods: The severity of motor function involvement was assessed by the ALSFRS-R scale at the initial evaluation. The fatty acid profile of erythrocyte membranes was analysed by gas-liquid chromatography. The study comprised 26 clinically diagnosed als patients, with mean ALSFRS-R 38±8. The control group included 26 healthy volunteers. Results: Significantly higher levels of palmitic acid and total saturated FAs were detected in als patients. In als patients, total monounsaturated FA, palmitoleic, vaccenic, and oleic acid were also significantly increased. The levels of eicosapentaenoic acid, docosapentaenoic acid, total polyunsaturated FA (PUFA) and n-6 PUFA were significantly lower in als patients. Additionally, a-linolenic acid, the precursor of the n-3 PUFA family, was not detected in als patients. We found no significant correlation between the ALSFRS-R score and the abundance of individual FAs analysed. A moderate negative correlation was found between disease duration and DHA level, and a positive correlation was detected with MUFA. Conclusion: Experimental evidence presented may contribute to shaping a beneficial nutritional intervention.

AB  - Transforming growth factor beta (TGF-β) is a ubiquitously distributed cytokine known to contribute to the pathogenesis of numerous pathological processes. The aim of this study was to measure serum concentrations of TGF-β1 in severely ill COVID-19 patients and to analyze its relationship with selected hematological and biochemical parameters and with the disease outcome. The study population included 53 COVID-19 patients with severe clinical expression of the disease and 15 control subjects. TGF-β1 was determined in serum samples and supernatants from PHA-stimulated whole blood cultures using ELISA assay. Biochemical and hematological parameters were analyzed using standard accepted methods. Our results showed that serum levels of TGF-β1 in COVID-19 patients and controls correlate with the platelet counts. Also, positive correlations of TGF-β1 with white blood cell and lymphocyte counts, platelet-to-lymphocyte (PLR) ratio, and fibrinogen level were shown, while negative correlations of this cytokine with platelet distribution width (PDW), D-dimer and activated partial thromboplastin time (a-PTT) values in COVID-19 patients were observed. The lower serum values of TGF-β1 were associated with the unfavorable outcome of COVID-19. In conclusion, TGF-β1 levels were strongly associated with platelet counts and unfavorable disease outcome of severely ill COVID-19 patients.

AB  - S. pneumoniae is an important human pathogen which has a polysaccharide capsule with virulent properties. This work aims to estimate the titres of S. pneumoniae specific IgG and IgA isotypes, with respect to age and sex. An in-house whole bacterial cell ELISA was used for the determination of relative levels and endpoint titres of IgG subclasses and IgA1 subclass specific for S. pneumoniae serogroup 1, and to quantify specific IgG1 and IgG2 levels. Significantly lower anti-pneumococcus IgG1 titres were found in older individuals, which was more pronounced in men. Lower IgG2 titres were detected in men over 50 years of age, in comparison to women under 50 years of age. The levels of IgG3 and IgG4 did not differ between different sex and age groups. Lower IgA1 levels were detected in male individuals in both age groups in comparison to females under 50 years of age. The levels of IgG1 showed a moderate correlation with IgG4 in younger individuals of both sexes (r = 0.61 in men and 0.63 in women) which was not noted in the older age group. We highlight the deficiency in humoral immunity in older people, especially male and suggest immunization of this population with pneumococcal vaccines.

AB  - In vivo animal models can provide worthy information on various aspects of asthma mechanism and pathogenesis. The genetic predisposition and phenotype of mice may affect the immune response itself. Here we compare the early immune response to Der p 2 or HDM allergen extract upon injection and inhalation in BALB/c and C57BL/6 mice. Female C57BL/6 and BALB/c mice were immunized with Der p 2 allergen subcutaneously followed by inhalation of Der p 2 or HDM extract. After challenge, the mice were euthanized; blood, bronchoalveolar lavage (BAL), spleens and lungs were collected. Cells from BAL were identified by May-Grünwald Giemsa staining and lung leukocyte populations were analyzed by flow cytometry. Serum antibody levels of Der p 2 specific IgE, IgG, IgG1 and IgG2a were assessed by ELISA, and cytokine secretion (IL-4, IFN-γ and IL-10) was evaluated upon stimulation with Der p 2 or HDM extract. The Th2 immune response was confirmed by elevated allergen-specific immunoglobulin E (IgE) and the allergic reaction was evidenced by infiltration of eosinophils and/or neutrophils into BAL. We found that BALB/c mice were inefficient in integrating local with systemic immune response, evidenced by almost no IgG or IgE production upon one subcutaneous injection and subsequent inhalation of Der p 2 allergen; also, the bronchoalveolar lavage infiltrate in these mice consisted of neutrophil infiltration, unlike C57BL/6 mice in which eosinophilic infiltrate predominated. The differences between BALB/c and C57BL/6 mice strains could be exploited for generating different types of responses to the Der p 2 allergen.

AB  - Increased interest in microbiota calls for the thorough analysis of antibody reactivity to different microorganisms. As salivary IgA represents the first line of defence against microorganisms contacting mucosal surfaces, we explored the binding and specificity of salivary IgA by testing the binding of purified, FITC-labelled salivary IgA to different microorganisms in flow cytometry and conclude that this kind of analysis enables the differentiation of species/strains with high IgA binding capacity, which should be corroborated on a larger sample size. Further we compare, with in-house ELISA, the binding of polyclonal salivary IgA with the binding of polyclonal serum IgA from the same individuals to whole microbial cells and to purified microbial components. High correlations were obtained in total salivary IgA binding to Lactobacillus rhamnosus and Escherichia coli, very distant bacterial species, as well as to isolated bacterial components (r =.70–.97). The binding of total salivary IgA resembled the binding of both salivary IgA1 and IgA2, with IgA2 predominating. For serum polyclonal IgA repertoire, substantially higher specificity was obtained. Serum IgA binding to E. coli correlated best with serum IgA binding to lipopolysaccharide (r =.86), and serum IgA against L. rhamnosus correlated best with the anti-peptidoglycan IgA levels (r =.88). We have also detected that total serum IgA response is governed by either IgA1 or IgA2 response, depending on the nature of the antigen/s. We conclude that steady state salivary IgA repertoire, unlike serum IgA repertoire, consists of polyreactive antibodies with innate specificity, questioning its capacity to select resident microbiota.

AB  - The predictors of intestinal carriage of vancomycin-resistant Enterococcus spp. (VRE) among high-risk patients in the counties of the Southeast Europe Region are insufficiently investigated, yet they could be of key importance in infection control. The aim of the study was to identify risk factors associated with fecal VRE colonization among high-risk inpatients in university hospitals in Serbia. The study comprised 268 inpatients from three university hospitals. Data on patient demographics and clinical characteristics, length of hospital stay, therapy, and procedures were obtained from medical records. Chi-squared tests and univariate and multivariate logistic regressions were performed. Compared to the hemodialysis departments, stay in the geriatric departments, ICUs, and haemato-oncology departments increased the risk for VRE colonization 7.6, 5.4, and 5.5 times, respectively. Compared to inpatients who were hospitalized 48 h before stool sampling for VRE isolation, inpatients hospitalized 3–7, 8–15, and longer than 16 days before sampling had 5.0-, 4.7-, and 6.6-fold higher risk for VRE colonization, respectively. The use of cephalosporins and fluoroquinolones increased the risk for VRE colonization by 2.2 and 1.9 times, respectively. The age ≥ 65 years increased the risk for VRE colonization 2.3 times. In comparison to the University Clinical Centre of Serbia, the hospital stays at Zemun and Zvezdara University Medical Centres were identified as a protector factors. The obtained results could be valuable in predicting the fecal VRE colonization status at patient admission and consequent implementation of infection control measures targeting at-risk inpatients where VRE screening is not routinely performed.

AB  - The surface of microorganisms is covered with polysaccharide structures which are in immediate contact with receptor structures on host's cells and antibodies. The interaction between microorganisms and their host is dependent on surface glycosylation and in this study we have tested the interaction of plant lectins with different microorganisms. Enzyme-linked lectin sorbent assay - ELLSA was used to test the binding of recombinant Musa acuminata lectin - BL to 27 selected microorganisms and 7 other lectins were used for comparison: Soy bean agglutinin - SBA, Lens culinaris lectin - LCA, Wheat germ agglutinin - WGA, RCA(120) - Ricinus communis agglutinin, Con A - from Canavalia ensiformis, Sambucus nigra agglutinin - SNA I and Maackia amurensis agglutinin - MAA. The goal was to define the microorganisms' surface glycosylation by means of interaction with the selected plant lectins and to make a comparison with BL. Among the tested lectins most selective binding was observed for RCA(120) which preferentially bound Lactobacillus casei DG. Recombinant banana lectin showed specific binding to all of the tested fungal species. The binding of BL to Candida albicans was further tested with fluorescence microscopy and flow cytometry and it was concluded that this lectin can differentiate ss-glucan rich surfaces. The binding of BL to S. boulardii could be inhibited with ss-glucan from yeast with IC50 1.81 mu g mL(-1) and to P. roqueforti with 1.10 mu g mL(-1). This unique specificity of BL could be exploited for screening purposes and potentially for the detection of ss-glucan in solutions.

AB  - The goal of this work was to elucidate similarities between microorganisms from the perspective of the humoral immune system reactivity in professional athletes. The reactivity of serum IgG of 14 young, individuals was analyzed to 23 selected microorganisms as antigens by use of the in house ELISA. Serum IgM and IgA reactivity was also analyzed and a control group of sex and age matched individuals was used for comparison. The obtained absorbance levels were used as a string of values to correlate the reactivity to different microorganisms. IgM was found to be the most cross reactive antibody class, Pearson's r = 0.7 +/- 0.92, for very distant bacterial species such as Lactobacillus and E. coli. High correlation in IgG levels was found for Gammaproteobacteria and LPS (from E. coli) (r = 0.77 for LPS vs. P. aeruginosa to r = 0.98 for LPS vs. E. coli), whereas this correlation was lower in the control group (r = 0.49 for LPS vs. P. aeruginosa to r = 0.66 for LPS vs. E. coli). The correlation was also analyzed between total IgG and IgG subclasses specific for the same microorganism, and IgG2 was identified as the main subclass recognising different microorganisms, as well as recognising LPS. Upon correlation of IgG with IgA for the same microorganism absence of or negative correlation was found between bacteria-specific IgA and IgG in case of Lactobacillus and Staphylococcusgeni, whereas correlation was absent or positive for Candida albicans, Enterococcusfaecalis, Streptococcus species tested in professional athletes. Opposite results were obtained for the control group. Outlined here is a simple experimental procedure and data analysis which yields functional significance and which can be used for determining the similarities between microorganisms from the aspect of the humoral immune system, for determining the main IgG subclass involved in an immune response as well as for the analysis of different target populations.

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.
