Summary

Story summary

Researchers identify PIEZO2-expressing neurons in the heart as crucial for maintaining blood pressure during posture and blood-volume changes.
A Nature study monitored mice shifting from horizontal to upright positions to observe the mechanism.
The neurons respond quickly to blood-volume changes, acting before arterial sensors.
Ardem Patapoutian, a Nobel Prize-winning biologist, emphasized the study's significance.
Further work is needed to clarify the roles of several cardiovascular neuron types.
