An immunogold investigation of the relationship between the amino acids GABA and glycine and their transporters in terminals in the guinea-pig anteroventral cochlear nucleus.

摘要

The majority of terminals contacting spherical bushy cell bodies in the guinea-pig anteroventral cochlear nucleus contain GABA, glycine or both (colocalizing). Double labeling with antibodies to each amino acid and the plasma membrane transporter for the other was performed using different sizes of gold particles. The transporter for GABA occurs in the plasma membranes of some terminals containing glycine and vice versa suggesting that colocalizing terminals can retrieve both amino acids.
