$GANX Most idiopathic PD cases, and virtually all GBA1 cases show misfolded/aggregated a-synuclein. Research is converging on Gcase dysfunction and sphingolipids as playing a primary role in this aggregation. "Lewy bodies” are the hallmark form of aggregated a-syn.
This recent peer-reviewed paper strengthens the rationale for 02287 by framing PD and related Lewy body diseases not only as proteinopathies, but also as lipid/lysosomal disorders. The key link is GCase dysfunction: reduced gcase activity impairs α-synuclein degradation while allowing toxic sphingolipids like GluSph to accumulate. The paper highlights that GluSph may directly promote α-syn aggregation. 2287’s reduction of GluSph is especially relevant — it lowers an upstream driver of α-syn pathology.
Not new information for those of us who have been following closely, but this paper is further evidence that the slow-moving science community is coming to the same conclusion that Gain came to years ago.
