Therapeutic Window Exists Because Amplified Signals (Not Baseline) Drive Pathog…

Mechanistic description

G2019S basal RAB10 phosphorylation elevation may be secondary; true pathogenic driver is amplified stress-response signaling. Partial LRRK2 inhibition sufficient to normalize stress-induced spikes while preserving necessary baseline functions. LRRK2 knockout mice viability supports non-essential baseline hypothesis. Age-dependent neurodegeneration in knock-in mice suggests stress-dependent pathology rather than chronic baseline elevation.
