    • The endogenous phospholipid l‐α‐lyso‐phosphatidylinositol (LPI) was recently identified as a novel ligand for the orphan G protein‐coupled receptor 55 (GPR55). In this study we define the downstream signaling pathways activated by LPI in a human embryonic kidney (HEK) 293 cell line engineered to stably express recombinant human GPR55. We find that treatment with LPI induces marked GPR55 internalization and stimulates a sustained, oscillatory Ca2+ release pathway, which is dependent on Gα13 and… CONTINUE READING
