LF 1695 is an immunomodulator. LF 1695 enhances the proliferative response of T cells by increasing the production of IL2 (interleukin-2) or the expression of the IL2 receptor. LF 1695 also increases CONA-induced inhibitory activity in human lymphocytes. LF 1695 can be used to study the proliferative and inhibitory activity of T cell subpopulations, as well as their role in immune regulation[1].
