alpha-Amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid, but not N-methyl-D-aspartate, activates mitogen-activated protein kinase through G-protein beta gamma subunits in rat cortical neurons.

Abstract

alpha-Amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor channels play important roles in plasticity, neurotransmission, and neurotoxicity in the central nervous system. AMPA, but not N-methyl-D-aspartate (NMDA), receptor signaling in rat cortical neurons was found to involve a G-protein coupled to a protein kinase cascade. While both NMDA… (More)
