Combined brain stimulation and acupuncture reshape neuroimmune pathways in TBI rats
A gene expression study in rats with traumatic brain injury examined the effects of combining repetitive transcranial magnetic stimulation with press-tack needle acupuncture. The treatment induced neuroimmune remodeling and activated neurotensin receptor 1 (NTSR1) signaling. These results suggest a molecular basis for the combined therapy's benefits.
This study in rats with traumatic brain injury combined two distinct therapies: repetitive transcranial magnetic stimulation, a noninvasive technique that uses magnetic fields to excite neurons, and press-tack needle acupuncture, a form of acupressure-like stimulation using tiny fixed needles. By analyzing gene expression, researchers identified that the combined treatment triggered neuroimmune remodeling—changes in how immune cells interact with brain tissue—and activated signaling through neurotensin receptor 1 (NTSR1), a receptor linked to pain modulation and inflammation. These molecular findings offer a plausible mechanism for why the combined approach may improve recovery after brain injury, though the work remains at a preclinical stage.
If these findings translate to humans, combined brain stimulation and acupuncture could offer a non-pharmacological option for traumatic brain injury rehabilitation, potentially reducing reliance on drugs with side effects. Patients with chronic post-injury symptoms, as well as clinicians seeking integrative therapies, may benefit. However, effects in rats do not guarantee human outcomes, and clinical trials would be needed. The work could also spur research into NTSR1 as a therapeutic target, but societal impact remains speculative until further validation.
