Prolonged ultra-low-intensity ultrasound suppresses pathological hyperactivity in hyperactive neurons and astrocytes via a CAV3–NCX1 complex, sparing basally active cells.
- Why it matters: Selective inhibition of pathological brain overactivity is a key therapeutic gap, and the molecular mechanism—and state selectivity—of ultrasound’s neural suppression is unclear.
- What they did: The study identifies the caveolin-3 (CAV3)-sodium-calcium exchanger-1 (NCX1) complex as a mediator, showing NCX1-dependent Ca2+ extrusion during ultrasound in hyperactive cells, with necessity and sufficiency tested and the CAV3–NCX1 interface disrupted.
- The result: In vivo, targeted ultrasound reduces fear-evoked hyperactivity and freezing and attenuates neuropathic pain-associated hyperactivity, allodynia, and hippocampal epileptiform activity in an NCX1-dependent manner.
