Fig. 7. Proposed mechanism of crowding-induced Piezo1 channel activation.

Fig. 7

The upper panel illustrates two distant Piezo1 channels remain inactive. The bottom panel illustrates two Piezo1 channels in close proximity are activated by crowding-induced arm flattening, revealing a multi-fenestrated ion permeation pathway. Symbols are defined in Eqs. (1a) and (1b).
