We studied by immunocytochemistry and Western blots the identity and cellular distribution of voltage-gated calcium channels within dopaminergic neurons of the rat retina. The aim was to associate particular calcium channel subtypes with known activities of the neuron (e.g., transmitter release from axon terminals). Five voltage-gated calcium channels were identified: alpha1A, alpha1B, alpha1E, alpha1F, and alpha1H. All of these, except the alpha1B subtype, were found within dopaminergic… CONTINUE READING
