摘要
An immediate reaction product of phosphatidylcholine hydrolysis catalyzed by phospholipase A2, lysophosphatidylcholine (lysoPC), synergizes with a membrane-permeable diacylglycerol, 1,2-dioctanoylglycerol, and ionomycin to activate resting T-lymphocytes as measured by interleukin-2 α-receptor expression. It is suggestive that both phospholipase C and phospholipase A2 are directly involved in signal transduction in a synergistic fashion and that lysoPC acts as an additional second messenger for cellular regulation, probably for long-term responses such as cell proliferation and differentiation. © 1991.
