Comparing 2 hypotheses side-by-side
Galectin-3 serves as a platform for NLRP3 inflammasome assembly and as a sensor of lysosomal damage. While the skeptic correctly notes that galectin-3 deletion prevents sensing rather than LMP itself, this remains therapeutically relevant if microglial NLRP3 activation is a primary driver rather than consequence. Existing pharmacologic tools (TD139 from IPF trials) provide translatable scaffold. Requires conditional knockout to avoid developmental compensation and careful monitoring of microglia
This hypothesis proposes that GluN2B-containing NMDA receptors in thalamocortical circuits directly regulate glymphatic system function through control of astrocytic aquaporin-4 (AQP4) polarization and cerebrospinal fluid flow dynamics. The mechanistic framework centers on thalamocortical gamma oscillations, which are critically dependent on extrasynaptic GluN2B receptors, serving as the primary driver of astrocytic calcium waves that maintain proper AQP4 clustering at perivascular endfeet.
