🧪 Overview

Small molecule enhancers of endogenous lectins (like galectin-3) could specifically recognize altered glycan patterns on tau vesicles and direct them toward autophagosomal degradation. This would create a selective clearance pathway for pathological tau aggregates.

IF galectin-3 (LGALS3) is pharmacologically enhanced via small molecule activators or viral overexpression in primary neurons seeded with pathological tau aggregates, THEN phosphorylated tau (p-tau Ser396) levels will decrease by at least 40% relative to vehicle controls within 48-72 hours of treatm

IF the carbohydrate recognition domain (CRD) of galectin-3 is required for tau clearance, THEN a CRD-mutant galectin-3 (R186S, critical for glycan binding) will fail to reduce pathological tau levels when overexpressed, while wild-type galectin-3 will reduce tau, in matched neuronal cultures within
Predicted outcome: Wild-type galectin-3 overexpression produces >35% reduction in tau aggregates; CRD-mutant produces <15% reduction (no different from empty vector)
Falsification: CRD-mutant galectin-3 produces equivalent tau reduction to wild-type, disproving the necessity of carbohydrate recognition domain for tau clearance and indicating a non-specific scaffolding function
