Biochem/physiol Actions

PalGly is an endogenous signaling lipid that modulates calcium influx and nitric oxide production. PalGly inhibits heat-evoked firing of wide dynamic range (WDR) neurons, activates calcium influx in DRG cells and stimulates NO production. Preliminary studies suggest its signaling mechanism involves GPCR-mediated cation channel activation and a Gαi/o-coupled signaling pathway, which is being further investigated.
