[Effects of diphenyl derivatives on electrophoretic mobility of murine T lymphocytes].

The early changes of electrophoretic mobility (EPM) of murine T lymphocytes induced by structural analogues of amixine-dihydrochloryde 4,4'-bis-[2(diethylamino)ethoxy]diphenyl (compound 1) and dihydrochloryde 2-methoxycarbonil-4,4'-bis-[2(diethylamino)ethoxy]diphenyl (compound 2) were studied by electrophoresis technique. During the interval 0-2 hours all compounds increased the absolute values of EPM in comparison with control. These changes were of the same kind--distinctions were quantitative. Amixine and compound 1 during the interval 2-4 hours additionally increased the EPM. The compound 2, on the contrary, decreased the EPM. It was shown that the opposite effects of the aforementioned compounds were caused by the fact that amixine and compound 1 induce, and compound 2 does not induce IFN production in T lymphocytes in vitro. The results of our experiments are important for understanding of the mechanisms of immunomodulating effect of amixine and its structural analogues.

[Effects of amixine on electrophoretic mobility of murine T lymphocytes].

The amixine-induced early changes in the electrophoretic mobility (EPM) of murine splenic T lymphocytes were studied in vitro by the microelectrophoresis technique. It has been found that T lymphocytes treated with amixine have a greater EPM within the first hours of amixine addition than control cells. This change in EPM depends on the concentration of amixine in the medium and the duration ofamixine exposure. It was concluded that the amixine-treated cells have a greater net negative surface charge density than control cells. This effect may play an important role in the cell-cell interaction during the immune response.
