| pubmed-article:1292694 | pubmed:abstractText | The action of some new MDP derivatives on functional activity of murine T-lymphocytes and macrophages was studied. The following tests have been used: proliferation of spleen cells in one-way allo-MLC; IL-1 and TNF production by peritoneal macrophages treated with the preparations. The most expressed enhancement of lymphocyte proliferative response in MLC has been exerted by beta C7H15 MDP and beta C16H33 MDP (stimulation indexes 31-69%). beta C7H15 MDP, beta C16H33 MDP and polyacrylamide-MDP (P-MDP) alone or in combination with LPS caused elevated secretion of IL-1 by macrophages. While beta C7H15 MDP was as active as MDP, beta C16H33 MDP and P-MDP manifested increased ability to stimulate IL-1 production in comparison with MDP. beta C7H15 MDP, beta C16H33 MDP, P-MDP and MDP induced similar level of TNF production by murine macrophages. However, simultaneous treatment of macrophages with beta C16H33 MDP and LPS resulted in more significant enhancement of TNF production than combination LPS + MDP. | lld:pubmed |
