Frontrunner target for Parkinson’s Disease may only be relevant for small fraction of patients

A recent study suggests that targeting alpha-synuclein protein in Parkinson's disease may not be sufficient to cure most patients. Instead, resolving brain inflammation caused by dysfunctional interferon-beta receptor signaling may hold the key to developing more effective treatments.
