PG - 47-52 LID - 10.1267/ahc.14049 [doi] AB - Bipolar cells transmit stimuli via graded changes in membrane potential and neurotransmitter release is modulated by Ca(2+) influx through L-type Ca(2+) channels. The purpose of this study was to determine whether the alpha1c subunit of L-type voltage-gated Ca(2+) channel (alpha1c L-type Ca(2+) channel) colocalizes with protein kinase C alpha (PKC-alpha), which labels rod bipolar cells. Retinal whole mounts and vertical sections from mouse, hamster, rabbit, and dog were immunolabeled with antibodies against PKC-alpha and alpha1c L-type Ca(2+) channel, using fluorescein isothiocyanate (FITC) and Cy5 as visualizing agents. PKC-alpha-immunoreactive cells were morphologically identical to rod bipolar cells as previously reported. Their cell bodies were located within the inner nuclear layer, dendritic processes branched into the outer plexiform layer, and axons extended into the inner plexiform layer. Immunostaining showed that alpha1c L-type Ca(2+) channel colocalized with PKC-alpha in rod bipolar cells. The identical expression of PKC-alpha and alpha1c L-type Ca(2+) channel indicates that the alpha1c L-type Ca(2+) channel has a specific role in rod bipolar cells, and the antibody against the alpha1c L-type Ca(2+) channel may be a useful marker for studying the distribution of rod bipolar cells in mouse, hamster, rabbit, and dog retinas.
