The synthetic analogue of phosphatidylserine, cholesterylphosphorylserine (CPHS) inhibits T-cellmediated immune responses in mice. Tested in cultured mouse spleen cells, CPHS inhibits concanavalin A-induced activation of DNA synthesis ( IC 50, 3.5 μM). Injected i.p. during the efferent phase, CPHS (...
