Serotonergic dysfunction precedes motor symptoms in PD; 5-HT1A/1B agonism proposed to reduce neuroinflammation. Despite high druggability, the mechanism lacks human causal validation and carries extensive clinical failure history including sarizotan, with no interventional evidence demonstrating cytokine modulation in CNS.
GBA1 mutations increase α-synuclein aggregation risk through glucosylceramide accumulation. Enhancement of GCase activity via chaperone therapy (ambroxol) or substrate reduction (GCS inhibitors) represents the strongest therapeutic approach with active clinical trials, favorable safety profile, and FDA orphan designation for genetically-defined PD subtype.
