Identification of novel Kv1.3 channel dependent mechanisms in microglial activation


ABSTRACT: Pro-inflammatory microglia contribute to disease progression in neuroinflammatory and neurodegenerative diseases. We identify novel Kv1.3 channel-dependent molecular and cellular mechanisms during microglial activation and unravel a Kv1.3-dependent pathway for MHCI-restricted antigen presentation by microglia to CD8+ T cells.

<h4>Background</h4>Kv1.3 potassium channels regulate microglial functions and are overexpressed in neuroinflammatory diseases. Kv1.3 blockade may selectively inhibit pro-inflammatory microglia in neurological diseases but the molecular and cellular mechanisms regulated by Kv1.3 channels are poorly defined.<h4>Methods</h4>We performed immunoblotting and flow cytometry to confirm Kv1.3 channel upregulation in lipopolysaccharide (LPS)-activated BV2 microglia and in brain mononuclear phagocytes fres  ...[more]
