Abstract
Cerebrovascular dysfunction occurs in Alzheimer's disease (AD), impairing hemodynamic regulation. Large conductance Ca2+-activated K+ channels (BKCa) regulate cerebrovascular reactivity and are impaired in AD. BKCa activity depends on intracellular Ca2+ (Ca2+ sparks) and nitro-oxidative post-translational modifications. However, whether these mechanisms underlie BKCa impairment in AD remains unknown.
期刊介绍:
Alzheimer's & Dementia is a peer-reviewed journal that aims to bridge knowledge gaps in dementia research by covering the entire spectrum, from basic science to clinical trials to social and behavioral investigations. It provides a platform for rapid communication of new findings and ideas, optimal translation of research into practical applications, increasing knowledge across diverse disciplines for early detection, diagnosis, and intervention, and identifying promising new research directions. In July 2008, Alzheimer's & Dementia was accepted for indexing by MEDLINE, recognizing its scientific merit and contribution to Alzheimer's research.
