title: [The effect of ladasten on the activation-induced expression of Fas receptor on T-lymphocytes and their sensitivity to Fas-induced apoptosis].
abstract: The effects of ladasten on the activation-induced expression of Fas-receptor on T-lymphocytes, their sensitivity to Fas-induced apoptosis, and the expression of mitogen-activated ERKI/ERK2 protein kinases have been studied. In the range of concentrations 0.1-10 microM, ladasten exhibited a comitogenic effect on the TCR-mediated stimulation of T-lymhocytes ion the peripheral human blood, which was accompanied by an increase in the level of phosphorylated form of ERK-2. At the same time, ladasten virtually did not change the activation-induced expression of Fas-receptor on T-lymphocytes, but reduced the rate of the Fas-induced apoptosis. It was concluded that the immunoprotective effect of ladasten is probably based on a decrease in the rate of Fas-induced apoptosis.
