Ontogeny of subunits 2 and 3 of the AMPA-type glutamate receptors in Purkinje cells of the developing chick cerebellum.

Several molecules, involved in cellular communication in the mature nervous system, appear to play important roles during neural development. These roles include neuronal growth, morphological changes of neurites, and neuronal survival. Such plasticity processes seem to be in part the result of activation of different receptor subtypes, which could cause Ca(2+) influx, a major candidate to be an outgrowth promoter. In this context, we performed immunohistochemical and in situ hybridization experiments to examine the following aspects of the development of chick cerebellum Purkinje cells: (i) expression of AMPA-type glutamate receptor GluR2/3 proteins; (ii) the levels of mRNAs coding for the GluR2 and GluR3 flip/flop isoforms; and (iii) expression of calbindin (CB) and parvalbumin (PV). Expression of GluR2/3 proteins, CB, PV, and the mRNAs coding for GluR2 and GluR3 splice variants all revealed a differential expression during development in chick Purkinje cells. GluR2/3 proteins and the GluR3 flop variant start to be expressed at E10, while the expression of CB, PV, the GluR3 flip isoform and the splice variants of GluR2 all started around E12-E14. All proteins showed an increasing expression from embryonic stages into the posthatching period. These results reveal a developmentally regulated expression of GluR2/3 proteins, including their splice variants, and of CB and PV in Purkinje cells. These findings may suggest a relationship between these proteins and specific cerebellar developmental processes.[1]
