The activation of cPLA2 and the expression of COX-2 in different cell types are regulated by multiple signaling pathways, including p38 MAPK pathway, which has been found to be activated in several neurological disorders that includes ischemic stroke, Alzheimer’s disease, Parkinson’s disease, and amyotrophic lateral sclerosis (10, 11, 36, 37). The gene discussed is PLA2G4A; the disease is early-onset autosomal dominant Alzheimer disease.
