PIEZO2 and channelopathy: The current author proposes that lost function of Piezo2 on type Ia fibers, due to detachment of proprioceptive terminals, also means that not only Piezo2 currents are lost (experienced during Piezo2 activation), but also subthreshold imbalanced cationic/Ca2+ currents as well (suggested under Piezo2 channelopathy).
