Understanding PIEZO2 mutations and sensory disorders
Every time we feel a gentle tap on the skin, specialized nerve cells convert that physical force into an electrical signal that the brain can interpret as touch. While scientists have long known that a protein called PIEZO2 acts as a key sensor for touch, it remained unclear why PIEZO2 is specialized for the localized mechanical forces experienced by sensory neurons, whereas its close relative PIEZO1 responds to broader mechanical stresses such as those generated when cells stretch, as occurs in blood vessels.
