This hypothesis proposes that pharmacological or genetic enhancement of TFEB (Transcription Factor EB)-mediated lysosomal biogenesis will attenuate NLRP3 inflammasome hyperactivation in microglia by promoting efficient clearance of inflammasome components and damage-associated molecular patterns (DAMPs). TFEB, the master regulator of lysosomal biogenesis and autophagy, controls expression of over 600 genes involved in lysosomal function, autophagosome formation, and cellular clearance mechanisms. In neuroinflammatory conditions, TFEB activity is suppressed through mTORC1-mediated phosphorylation, leading to its cytoplasmic sequestration and reduced lysosomal capacity. This creates a bottleneck in the degradation of activated NLRP3 inflammasomes, prolonging IL-1β and IL-18 secretion.

This hypothesis proposes that pharmacological or genetic enhancement of TFEB (Transcription Factor EB)-mediated lysosomal biogenesis will attenuate NLRP3 inflammasome hyperactivation in microglia by promoting efficient clearance of inflammasome components and damage-associated molecular patterns (DAMPs). TFEB, the master regulator of lysosomal biogenesis and autophagy, controls expression of over 600 genes involved in lysosomal function, autophagosome formation, and cellular clearance mechanisms. In neuroinflammatory conditions, TFEB activity is suppressed through mTORC1-mediated phosphorylation, leading to its cytoplasmic sequestration and reduced lysosomal capacity. This creates a bottleneck in the degradation of activated NLRP3 inflammasomes, prolonging IL-1β and IL-18 secretion. The hypothesis centers on the mechanism whereby TFEB enhancement promotes: (1) increased expression of lysosomal cathepsins that degrade NLRP3 and ASC components, (2) enhanced autophagic flux that removes cytosolic inflammasome aggregates, (3) improved clearance of extracellular DAMPs through enhanced phagocytic capacity, and (4) restoration of lysosomal pH homeostasis that optimizes degradative enzyme function. Therapeutic interventions targeting TFEB nuclear translocation through mTOR inhibition, TFEB phosphorylation modulation, or direct TFEB activators would restore microglial clearance capacity, breaking the cycle of persistent inflammasome activation. This approach shifts focus from mitochondrial quality control to lysosomal enhancement while maintaining the core objective of attenuating chronic NLRP3-driven neuroinflammation in neurodegenerative diseases.
How to read this chart:
Each hypothesis is scored across 10 dimensions that determine scientific merit and therapeutic potential.
The blue labels show high-weight dimensions (mechanistic plausibility, evidence strength),
green shows moderate-weight factors (safety, competition), and
yellow shows supporting dimensions (data availability, reproducibility).
Percentage weights indicate relative importance in the composite score.
