Baroreceptor Mechanotransduction: Diverse Sensors, Unified Signals

The authors investigate the mechanisms of mechanotransduction in arterial baroreceptors, questioning whether specific ion channels like PIEZO1/2 are essential for barosensing or if other channels such as TRPs and ENaCs can also fulfill this role in a context-dependent manner. They aim to reconcile the diverse structural and functional characteristics of baroreceptors, suggesting that their ability to encode pressure stimuli is influenced by a complex interplay of channel composition, terminal architecture, and afferent excitability, rather than relying on a single mechanosensory pathway.
