Abstract

In slices of adult rat cerebellum inositolphospholipid turnover is stimulated markedly by glutamate and its rigid analogues quisqualate and ibotenate. The drug and amino acid specificity of the responses reflects a quisqualate-preferring excitatory amino acid receptor. The absence of glutamate-enhanced inositolphospholipid turnover in mice with Purkinje-cell degeneration indicates that the inositolphospholipid-linked quisqualate receptor mediates parallel fiber-Purkinje cell synaptic transmission. The quantitative prominence of this synapse accounts for the massive enrichment of elements of the inositolphospholipid system in cerebellar Purkinje cells.
