AB  - Dendritic cells (DC) are responsible for the initiation and shaping of the adaptive immune response and are in the focus of autoimmunity research. We were interested in comparison of DC obtained from autoimmunity-prone Dark Agouti (DA) rats and autoimmunity-resistant Albino Oxford (AO) rats. DC were generated from bone marrow precursors and matured (mDC) by lipopolysaccharide. Tolerogenic DC (tolDC) obtained by vitamin D3 treatment were studied in parallel. Profile of cytokine production was different in AO and DA mDC and tolDC. Expression of MHC class II molecules and CD86 were higher in DA DC, while vitamin D3 reduced their expression in dendritic cells of both strains. Allogeneic proliferation of CD4+ T cells was reduced by AO tolDC, but not with DA tolDC in comparison to respective mDC. Finally, expression of various genes identified as differentially expressed in human mDC and tolDC was also analyzed in AO and DA DC. Again, AO and DA DC differed in the expression of the analyzed genes. To conclude, AO and DA DC differ in production of cytokines, expression of antigen presentation-related molecules and in regulation of CD4+ T proliferation. The difference is valuable for understanding the divergence of the strains in their susceptibility to autoimmunity.

AB  - Cucumber (Cucumis sativus) fruit has been used in cuisine worldwide, while its leaves are rich in immunomodulatory compounds. Cucumber leaf extract (CLE) was characterized by the predominance of triterpenoids cucurbitacins and significant levels of phenolics. Effects of CLE on CD4 + T helper (Th) cells and macrophages, as the major encephalitogenic cells in the autoimmunity of the central nervous system were investigated in our study. CLE potently inhibited production of major pathogenic Th cytokines: interferon-gamma and interleukin-17, as well as of nitric oxide and reactive oxygen species in macrophages. Antigen-presenting activity of macrophages and dendritic cells was also affected by CLE. The effects of CLE were co-incident with modulation of NFκB and p38 MAPK signaling. Concentrations of CLE used in vitro did not show toxic effects on zebrafish embryos. Moreover, CLE inhibited generation of encephalitogenic cells in vivo. These results demonstrate that CLE deserve further investigation on its anti-encephalitogenic therapeutic properties.

AB  - Cucurbitacin E (CucE) is a highly oxidized steroid consisting of a tetracyclic triterpene. It is a member of a Cucurbitacin family of biomolecules that are predominantly found in Cucurbitaceae plants. CucE has already been identified as a potent anti-inflammatory compound. Here, its effects on CD4(+) T helper (Th) cells and macrophages, as the major encephalitogenic cells in the autoimmunity of the central nervous system, were investigated. Production of major pathogenic Th cell cytokines: interferon-gamma and interleukin-17 were inhibited under the influence of CucE. The effects of CucE on CD4(+) T cells were mediated through the modulation of aryl hydrocarbon receptor, STAT3, NFκB, p38 MAPK, and miR-146 signaling. Further, production of nitric oxide and reactive oxygen species, as well as phagocytic ability, were inhibited in macrophages treated with CucE. These results imply that CucE possesses powerful antiencephalitogenic activity.

AB  - NO-hybridization of the HIV protease inhibitor Saquinavir generates a new chemical entity named Saq-NO, that retains the anti-viral activity and exerts lower toxicity. We show that Saq-NO inhibited the generation of various cytokines in ConA-stimulated unfractionated murine spleen cells and rat lymph nodes stimulated with ConA as well as in purified CD4(+) T cells in vitro and reduced the circulating levels of cytokines in mice challenged with anti-CD3 antibody. Furthermore, Saq-NO reduced IL-17 and IFN-gamma production in myelin basic protein (MBP)-specific cells isolated from rats immunized with MBP. These findings translated well into the in vivo setting as Saq-NO ameliorated the course of the disease in two preclinical models of multiple sclerosis. Our results demonstrate that Saq-NO exerts immunomodulatory effects that warrant studies on its application in autoimmune diseases. (c) 2013 Elsevier B.V. All rights reserved.

AB  - Background: The mutant CCR5Δ32 allele confers resistance to HIV infection. Several hypotheses regarding its origin and persistence in the human population have been proposed. It is assumed that the Δ32 mutation was introduced in Northern or Eastern Europe and that it spread to the south. Although the frequency of CCR5Δ32 was determined in numerous European nations and regions, further data are needed to complete the puzzle of CCR5Δ32 distribution within the continent. Methods: To this end, CCR5Δ32 frequency was determined in a Serbian population (sample size 352). DNA was extracted from peripheral whole blood and polymerase chain reaction specific for CCR5 gene was performed. A reaction product of 263 bp was obtained from the wild­type CCR5 sequence and a product of 231 bp was obtained from the truncated CCR5Δ32 sequence. Results: Overall allele frequency of CCR5Δ32 is 4.55%; 0.57% of individuals in the examined population are homozygous and 8.52% are heterozygous for CCR5Δ32. Conclusions: The determined frequency of the CCR5Δ32 allele in a Serbian population is unexpectedly low, considering ethnically related populations.
AB  - Uvod: Nosioci alela CCR5Δ32 su relativno rezistentni na infekciju HIV-om. Postoji nekoliko hipoteza o poreklu i održanju ovog alela u ljudskoj populaciji. Pretpostavlja se da je mutacija Δ32 nastala u populaciji severne ili istočne Evrope i da se potom proširila ka jugu. Iako je učestalost CCR5Δ32 određena u mnogim evropskim populacijama, dodatni podaci su neophodni za formiranje sveobuhvatne slike o distribuciji CCR5Δ32 u Evropi. Zbog toga smo u našoj studiji odredili učestalost CCR5Δ32 u srpskoj populaciji, za koju do ovog rada nisu postojali takvi podaci. Metode: DNK je izolovana iz periferne krvi 352 osobe. U reakciji lančanog umnožavanja korišćeni su prajmeri specifični za gen CCR5. Dobijen je proizvod od 263 bp na osnovu matrice 'wild type', sekvence CCR5 gena, a proizvod od 231 bp na osnovu okrnjene sekvence gena CCR5 (CCR5Δ32). Ukupna učestalost alela CCR5Δ32 u srpskoj populaciji iznosi 4,55%. Rezultati: Od ukupnog broja analiziranih osoba, identifikovano je 8,52% heterozigotnih i 0,57% homozigotnih nosilaca za ovaj alel. Zaključak: Utvrđena učestalost alela CCR5Δ32 u srpskoj populaciji je neočekivano niska, u poređenju sa učestalošću u ostalim slovenskim populacijama.
