Lysophosphatidic acid signalling

Curr Opin Cell Biol. 1995 Apr;7(2):203-10. doi: 10.1016/0955-0674(95)80029-8.


Lysophosphatidic acid is an intercellular phospholipid messenger that is released from platelets (and probably other cells) and evokes multiple biological responses, ranging from induction of mitogenesis to neurite retraction, by activating a specific G protein coupled receptor. Recent studies indicate that the lysophosphatidic acid receptor acts via the small GTP-binding proteins Ras and Rho to stimulate cell proliferation and to trigger actin-based cytoskeletal events, respectively.
