Аннотация: Glycolipid biosurfactant (GLB) from Rhodococcus ruber IEGM 231 was found to stimulate tumor necrosis factor-α (TNF-α), interleukin (IL) -1β and IL-6 production when applied as an ultrasonic emulsion to the adherent human peripheral blood monocyte culture. However, a lack of cytokine-stimulating activity was registered with the GLB applied as a hydrophobic film coating in 24-well culture plates, indicating that it may have been due to its inhibitory effect on monocyte adhesion. The mode of GLB application may therefore play an important role in in vitro assay of immunostimulatory activity of this compound as well as other bacterial glycolipids. Additionally, GLB from R. ruber displayed no cytotoxicity against human lymphocytes and therefore could be proposed as a potential immunomodulating and antitumor ag

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
