Research Abstract

Functional involvement of PKCγin the etiology of SCA14 and Parkinson disease was studied in cells and animals. We found 1) mutant PKCγs form amyloid-like fibrils in Purkinje cells and the formation was inhibitied by trehalose, 2) dysfunction of PKCγcould cause Parkinson disease by the inhibition of dopamine release and the loss of dopaminergic neurons in the substantia nigra.
