abstract = {Proton channels are transmembrane proteins that enable
selective proton (H+) transport. The voltage-gated proton
channel Hv1 or HVCN1 is the only one found in mammalian
cells, primarily in immune cells, where it facilitates rapid
proton extrusion in response to membrane depolarization,
mediating outward proton currents. Therefore, it is well
equipped to support NADPH-oxidase function, facilitating the
proton flux that maintains physiological pH and membrane
potential for efficient reactive oxygen species (ROS)
production. In the central nervous system (CNS), Hv1 is
predominantly found in microglia. Its role in microglia
homeostasis is yet to be elucidated; however, recent
research has highlighted its involvement in neurological
conditions, including demyelinating disease, spinal cord
injury, stroke, and Parkinsonism. These studies have shown
beneficial effects of Hv1 deletion, including improved
neurological function, reduced microglial activation,
enhanced myelination, and decreased neuroinflammation. This
review explores the role of Hv1 in the CNS and its potential
as a therapeutic target in neurodegenerative diseases.},
