Con A-binding glycoproteins in the developing cerebellum of control and hypothyroid rats.
Concanavalin A (Con A)-binding glycoproteins were studied during the postnatal development of the cerebellum of control and hypothyroid rats. Only 4 glycoprotein bands have a transient behavior in control animals. They progressively increase until the 13th day and markedly decline between the 15th and the 18th postnatal day. In the cerebellum of hypothyroid rats, the level of these compounds is greatly reduced and the previous decrease observed in controls is not found again. This defect of Con A-binding glycoproteins mainly localized on the plasma membrane of parallel fibers might be related to the reduced synaptogenesis observed in the molecular layer of hypothyroid rats between parallel fibers and Purkinje cell dendritic spines.
