Various strains of mycoplasmas cause activation of transcriptional factor NF-kB as a result of interaction with different combinations of Toll-like receptors (TLR). It is well known that the MALP-2 protein of M. fermentans activates the NF-kB through interaction with the TLR2/6, lipid-associated membrane lipopeptides (LAMPs) of M. penetrans through the TLR1/2, LAMPs of M. pneumoniae through combinations of Toll-like receptors (TLR2/6 and TLR1/2), and superantigene of M. arthritidis through the TLR2 and TLR4-dependent pathways. In this study, we defined specific Toll-like receptors for LAMPs of M. arginini. For carrying out the research we used cell lines 293-null, 293-hTLR2, 293-hTLR1/2, 293-hTLR2/CD14, 293-hTLR2/6, 293-hTLR4/ CD14-MD2 expressing certain combinations of TLR and their coreceptors. It was shown that LAMPs of M. arginini cause activation of NF-kB interacting with TLR2/1, TLR2/6 and TLR2/ CD14, but not with TLR2 alone or TLR4.
