ABSTRACT
Objective To investigate the expression of ?-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid(AMPA) receptor subunit proteins GluR2/3 in the postnatal rat cochlear nucleus(CN), and the relationship with the auditory brainstem response(ABR).Methods The thresholds of ABR of different age SD rats were recorded respectively,and the expression of GluR2/3 in CN was detected with FITC-immunocytochemistry.Results ①P1w SD rats did not show ABR wave, and there was no significant difference in the ABR threshold among P4w,P9w and P15w SD rats. ②GluR2/3 was expressed in all sorts of neurons of CN of every postnatal groups, the expression of P4w rats was denser than that of P1w, P9w and P15w rats. The immunostaining of P4w rats was located at the cell membrance, while P9w and P15w rats in the endochylema majoritily. Conclusion The different expression and distribution of GluR2/3 in different age rat CN may be involved in the development of auditory centre.
