Abstract : Glutamate excitotoxicity plays a crucial role in the pathogenesis behind the development and progression of several neurodegenerative diseases. The study aimed to investigate the neuroprotective activity of Gallic acid (GA) against glutamate-induced neurotoxicity in primary rat cortex neurons (RCN). Treated the RCNs with GA 25 & 50 μg/ml for 2 h and later treated the cells with 100 μM glutamate (GLU) and incubated for 24 h at 37 °C. The results demonstrated that, the GA improved the antioxidant profile in the cortex neurons and inhibited the production of the proinflammatory cytokine. GA also maintained the Ca2+ homeostasis, IGF-1 expression, and protected the neurons from glutamate-induced neuronal toxicity. The neuroprotective activity of GA has further confirmed from the results of N-acetylaspartate and expression of microtubule-associated protein-2 expression. The reports suggest that, GA is significantly attenuated the glutamate-induced neurotoxicity and protected neurons from various chemical events that are involved in the pathogenesis of neurotoxicity.
