Comparative StudyImmunocytochemical localization of calretinin containing neurons in retina from rabbit, cat, and dog.
Calcium homeostasis is critical for many neuronal functions, yet the distribution of calcium-binding protein is not always conserved among species, even between closely related species. We decided therefore to study the distribution of one of these calcium-binding proteins calretinin, in retina from rabbit, cat, and dog. Calretinin was localized using antibody immunocytochemistry. ⋯ The present study suggests that calretinin immunoreactivity is present in several populations in the retina. In particular, calretinin labels AII amacrine cells and a subpopulation of ganglion cells in all three animals. Horizontal cells, however, were not labeled in rabbit.
