PG - 345-9 AB - In primary cultures of cerebellar granule cells excitatory amino acid recognition sites are coupled with the stimulation of inositol phospholipid (PI) hydrolysis, cGMP formation and 45Ca2+ uptake. Mg2+, 2-amino-5-phosphonovalerate (APV) and phencyclidine (PCP) potently inhibit signal transduction in response to N-methyl-D-aspartate (NMDA), glutamate (GLU) and aspartate (ASP). Activation by quisqualate (QUIS) is transduced selectively into stimulation of PI hydrolysis and this response is not sensitive to inhibition by Mg2+, APV and PCP. Activation by kainate (KA) is transduced into potent stimulation of cGMP formation and 45Ca2+ uptake. Transduction of KA signal is not affected by Mg2+ and is relatively insensitive to PCP and APV.
