PIEZO1 (Piezo Type Mechanosensitive Ion Channel Component 1): PIEZO1 is a mechanically activated ion channel that plays a critical role in sensing mechanical stimuli like pressure and stretch in various tissues, including blood vessels and the lungs. Its function is crucial for vascular development, blood pressure regulation, and cell volume regulation. Mutations in PIEZO1 are linked to hereditary xerocytosis, a condition characterized by dehydrated red blood cells, and to other disorders involving mechanosensation....
