Can vagal nerve stimulation combined with GLP-1R agonists synergistically enhance neuroprotection in PD models?

OPEN

The debate proposed vagal-mediated neuroprotective signaling but lacked evidence for therapeutic synergy between electrical stimulation and pharmacological GLP-1R activation. This combination approach could offer a novel dual-modality treatment if mechanistically validated.
