Closed-loop transcranial focused ultrasound (cl-tFUS) entraining hippocampal gamma oscillations creates an optimal neuronal state for lncRNA therapeutic uptake, while plasma p-tau217 levels guide precise timing and dosing of MSC exosome delivery. When plasma p-tau217 reaches elevated but pre-loss thresholds (Braak III-IV), gamma entrainment via parvalbumin (PV) interneuron activation creates a permissive cellular environment through CREB-mediated transcriptional enhancement. This primed state am
CSF p-tau217 serves as a predictive biomarker for optimal lncRNA-0021 (via MSC exosome) therapeutic intervention timing, with the greatest efficacy observed when plasma p-tau217 levels are elevated but before significant neuronal loss (Braak stage III-IV). Implementing p-tau217-guided dosing windows prevents premature treatment termination and allows personalized exosome dosing calibration to maximize miR-6361 sequestration restoration without off-target effects.
