Protein kinase Cγ negatively regulates the intrinsic excitability in zebrin-negative cerebellar Purkinje cells.

Protein kinase C γ (PKCγ), a neuronal isoform present exclusively in the central nervous system, is most abundantly expressed in cerebellar Purkinje cells (PCs). Targeted deletion of PKCγ causes a climbing fiber synapse elimination in developing PCs and motor deficit. However, physiological roles of PKCγ in adult mouse PCs are little understood.

Development of microglia-targeting adeno-associated viral vectors as tools to study microglial behavior in vivo.

Here we describe the microglia-targeting adeno-associated viral (AAV) vectors containing a 1.7-kb putative promoter region of microglia/macrophage-specific ionized calcium-binding adaptor molecule 1 (Iba1), along with repeated miRNA target sites for microRNA (miR)-9 and miR-129-2-3p. The 1.

Electrophysiological and Imaging Analysis of GFP-Tagged Protein Kinase C γ Translocation in Cerebellar Purkinje Cells.

The cerebellum contains the highest density of protein kinase C (PKC) in the central nervous system. PKCγ, the major isotype accounting for over half of the PKCs in the cerebellum, is expressed exclusively in Purkinje cells (PCs). Inactivated PKCγ, which is localized in the cytoplasm of PC dendrites and soma, begins to translocate to the cell membrane upon activation.
