ABSTRACT

Activation of excitatory amino acid receptors increased [3H]phorbol-12,13-dibutyrate ([3H]PdBu) binding in four week cultures of striatal cells from postnatal day 7 rat pups (PN7), and in PN7 cells co-cultured the fourth week with striatal cells from postnatal day 1 rat pups. Kainate (KA), trans-1-amino-cyclopentyl-1,3-dicarboxylate (ACPD), and N-methyl-D-aspartate (NMDA) increased [3H]PdBu binding equally in both types of cultures, but alpha-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid (AMPA) increased binding by 3-fold in the co-cultures. Thus, [3H]PdBu binding in these two types of striatal cultures offers a simple model system for studying the regulation of AMPA/KA receptor responses.
