[Gq-GPCR upregulation in reactive astrocytes: implication for neurological disorders].
Astrocytes are essential glial cells that maintain brain homeostasis. Upon brain injury, they become reactive astrocytes with altered morphology, gene expression, and function, including dysregulated Ca2+ signaling implicated in disease development and progression. P2Y1 receptor (P2Y1R), one of Gq-GPCRs, is upregulated...
