Ключевые слова (''Своб.индексиров.''): 5-n-dodecyl resorcinol--cytotoxicity--apoptosis
Аннотация: Small molecules originating from microbes (SMOMs) play a significant role in bacterial-bacterial communication and in interactions between bacteria and their hosts. The aim of this study is a comparative analysis of the cytotoxic activity to human granulocytes and monocytes of two structurally close SMOMs: N-dodecanoyl-L-homoserine lactone (C12-HSL) and 5-N-dodecyl resorcinol (C12-AR). Cell viability was determined by Trypan blue dye exclusion. To distinguish cell death mechanisms, both necrosis and apoptosis tests were carried out. Cells undergoing apoptosis were identified by caspase-3 activity and the level of histone-associated DNA fragments. To evaluate cell lysis, the lactate dehydrogenase release test was used. In addition, the SMOM's action on erythrocyte membrane stability was investigated. The investigated SMOMs in micromolar concentrations showed more dose-dependent cytotoxicity against granulocytes than monocytes, but they used different mechanisms to impinge on the cell death pathway. C12-HSL specifically induced apoptosis similar to the activity previously reported for 3-oxo-N-dodecanoyl-L- homoserine lactone that originated from Pseudomonas aeruginosa. In contrast, C12-AR induced fast cytolytic effects (necrosis) as shown by the release of cytoplasmic lactate dehydrogenase, and presumably were defined by cellular membrane destabilisation. Our data demonstrate that both C 12-HSL and C12-AR can eliminate key defence cells, which would otherwise participate in the destruction of pathogenic bacteria. These results reinforce the SMOMs bifunctionality concept that such bacterial molecules not only regulate bacterial-bacterial interactions but also break immune defences as a new and important mechanism of host evasion

Аннотация: We studied the role of monocytes in the effect of myelopid and myelopeptides MP-1, MP-3, MP-5, and MP-6 on functional activity of peripheral blood lymphocytes in the reaction of blast transformation. Myelopeptides MP-1, MP-3, and MP-6 suppressed blast transformation of lymphocytes. The effect depended on the presence of monocytes in a cell culture

Заглавие : Modulation of Cytokine secretion and oxidative metabolism of innate immune effectors by Rhodococcus Biosurfactant

Ключевые слова (''Своб.индексиров.''): rhodococcus rubber--glycolipid biosurfactant--interleukin-10
Аннотация: The glycolipid biosurfactant complex from Rhodococcus ruber IEGM 231 had a stimulatory effect on the production of IL-12, IL-18, and reactive oxygen species by cells of the innate immunity. This effect depended on the composition of cell cultures and presence of LPS. It was primarily observed in non-stimulated cultures. The glycolipid biosurfactant complex had little effect on IL-10 secretion by monocytes and mononuclear cells

Заглавие : Homoserine lactones and resorcinolic lipids inhibit In vitro pro-and anti-inflammatory cytokine production

Ключевые слова (''Своб.индексиров.''): homoserine lactones--resorcinolic lipids --immune system
Аннотация: Homoserine Lactones (HSLs) and Resorcinolic Lipids (RLs) originating from microbes and plants influence immune system, however, it is currently unclear whether HSLs and RLs are activators or suppressors of the cytokine network, especially in humans. A study has been carried out to investigate the effects of pure, synthetic HSLs and RLs with different chain lengths on pro-and anti-inflammatory cytokines produced by human blood monocyte cultures. Human monocytes (macrophages and lymphocytes) were collected from leukocyte-rich plasma, separated on a double density gradient, pre-treated with HSLs or Rls and then were inducted with standard either lipopolysaccharide or phytohemagglutinin stimulus. Quantitative assays for pro-and anti-inflammatory cytokines in the monocyte culture supernatants were performed using enzyme immunoassay kits for the quantitative determination of IL-1β, IL-2, IL-4, IL-10, TNF-α and IF-γ. We observed differences in cytokine production according to HSL and RL pre-treatment, increasing in the following order: IL-1β→IL-2≈IL-10≈TNF-α→IL-4→IF-γ. HSLs have been shown more pronounced inhibitory effects than Rls and long-chained homologs were more active than short-chained ones. Our study suggests that some small molecules originating from microbes and plants play an important role in cytokine network regulation and the immunomodulatory effect of HSLs and RLs may obstruct host defenses and affect inflammatory processes

Заглавие : The role of monocytes in the effects of β-endorphin and selective agonists of μ-and δ-opiate receptors on the proliferative activity of peripheral blood lymphocytes

Ключевые слова (''Своб.индексиров.''): monocytes--beta endorphin--blood lymphocytes
Аннотация: The effects of β-endorphin under the conditions of naloxone hydrochloride blockade of opiate receptors, as well as the effects of the selective agonists of μ-and δ-receptors DAGO and DADLE and the effects of melanocyte-potentiating factor (MPF), on the in vitro proliferative response of lymphocytes were studied. The dose-effect dependence indicated stimulating effects of β-endorphin, DAGO, and DADLE on the proliferative response in the presence of phytohemagglutinin (PHA). The tetrapeptide MPF, which is the C-terminal sequence of β-endorphin, had almost no effect on the proliferative activity of lymphocytes. β-Endorphin, naloxone, and the μ-and δ-receptor selective agonists enhanced the proliferative response of lymphocytes in an unfractionated cell culture, whereas β-endorphin, naloxone, and DAGO suppressed the proliferative activity of lymphocytes in the mononuclear fraction purified of monocytes. In both cases, the naloxone blockade of opiate receptors enhanced rather than eliminated the β-endorphin e
