Co-localization of parvalbumin and glycine in pyriform amacrine cells in the goldfish retina

Purpose. A majority of retinal amacrine cells (Acs) either contain the inhibitory amino acid neurotransmitter GABA or glycine (GLY). In the mammalian retina, a subpopulation of glycinergic amacrine cells contains the calcium binding protein, parvalbumin (PARV). Double-label immunohistochemistry was used to determine if GLY and PARV were co-localized in the goldfish retina. Methods. Eyecups were fixed in 4% paraformaidehyde and 0.5% acrolein for …
