Does TFEB activation directly restore mutant GBA enzyme activity or only enhance lysosomal biogenesis?

PARTIALLY ADDRESSED

The debate identified this as a critical mechanistic gap - TFEB may increase lysosomal volume without addressing the fundamental GBA enzyme defect. This distinction is essential for determining therapeutic efficacy and predicting which GBA mutations would respond. Source: Debate session sess_SDA-2026-04-10-gba-pd (Analysis: gba-pd)
