Abstract
Calbindin D-28K and parvalbumin immunocytochemistry were used in the study of central ganglionic cell tumors. Most neurons in the ganglioglioma were immunoreactive to calbindin D-28K, but a few cells were labeled with antibodies against parvalbumin. In contrast, most cells in dysplastic gangliocytoma of the cerebellum were parvalbumin immunoreactive, but fewer reacted with anti-calbindin antibodies. These latter cells had two or three dendrites with claw-shaped terminals and axons with recurrent collateral branches and varicose terminals filled with strings and buttons. These observations suggest that central ganglionic cell tumors, including dysplastic gangliocytoma of the cerebellum, are composed of neurons which, on the basis of their calcium-binding protein content, have particular metabolic and electrophysiological properties.
