For evaluation of effects of release-active antibodies to CD4 on cultured lymphocytes from human peripheral blood, we measured intracellular content of lck-kinase cell-based ELISA. In cells treated with release-active antibodies to CD4, the content of intracellular lck-kinase significantly (p<0.01) decreased in comparison with the control (purified water processed in a similar way). Phytohemagglutinin had no effect on the concentration of lck-kinase in cells. The decrease in the content of CD4-associated lck protein suggests that the preparation enhanced intracellular coupling of lck-kinase with T-cell receptor and potentiated T-cell immune response.
