PV interneurons co-release NPY, which signals via Y1 receptors on excitatory terminals to suppress glutamate release and inhibit Aβ-induced oxidative stress. Closed-loop stimulation of PV interneurons amplifies NPY release, providing neuroprotection against Aβ-induced ROS accumulation. The critical weakness is NPY source ambiguity: NPY is also expressed in somatostatin interneurons, and Aβ-induced NPY decline may not be PV-specific. Falsification requires PV-specific NPY knockout experiments, wh
Aβ oligomers downregulate KCNQ2/3 voltage-gated potassium channels on PV interneurons via PKC-dependent phosphorylation, reducing accommodation and impairing theta-frequency resonance. Pharmacological or optogenetic restoration of M-current kinetics reinstates theta rhythmicity. This hypothesis benefits from the strongest pharmacological precedent (retigabine already shown effective in Tg2576 mice) but the optogenetic ChR2-proposed component is mechanistically inelegant—sustained depolarization
