Comparing 2 hypotheses side-by-side
LAMP-2 is critical for lysosomal membrane stability, lysosome-lysosome fusion, and chaperone-mediated autophagy. AAV9-mediated LAMP-2 delivery aims to stabilize lysosomal membranes and reduce cathepsin release. However, the mechanistic link from LAMP-2 deficiency to AD-specific LMP is not established—Danon disease represents a different pathological process (failed autophagosome-lysosome fusion) than hypothesized for AD. Isoform-specific effects (LAMP-2A vs LAMP-2B) add complexity.
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.
