MELISSA OFFICINALIS ACIDIC FRACTION PROTECTS CULTURED CEREBELLAR GRANULE NEURONS AGAINST BETA AMYLOID-INDUCED APOPTOSIS AND OXIDATIVE STRESS

Objective Extracellular deposition of the beta-amyloid (Aβ) peptide, which is the main finding in the pathophysiology of Alzheimer’s disease (AD), leads to oxidative damage and apoptosis in neurons. Melissa officinalis (M. officinalis) is a medicinal plant from the Lamiaceae family that has neuroprotective activity. In the present study we have investigated the protective effect of the acidic fraction of M. officinalis on Aβ-induced oxidative stress and apoptosis in cultured cerebellar granule neurons (CGN). Additionally, we investigated a possible role of the nicotinic receptor.
