IF pharmacologic ATP6V1A activation (v-ATPase agonism) is administered to human iPSC-derived neurons harboring sporadic Alzheimer's disease-risk genetics at 100 nM for 72 hours, THEN fluorescent pH-sensitive lysosomal reporter ratio will normalize from pathological alkaline values (pH >5.5) toward h
Predicted outcome: Lysosomal pH will shift from alkaline (pH 5.6±0.3) to acidic (pH 5.0±0.2) range, with concurrent TFEB nuclear translocation increasing by ≥40% (from 1
Falsification: Lysosomal pH remains >5.3 and TFEB nuclear:cytoplasmic ratio remains <30% despite drug treatment, indicating no measurable target engagement or downstream pathway activation.
