The pathological spread of tau aggregates in Alzheimer's disease relies critically on heparan sulfate proteoglycan (HSPG)-mediated neuronal uptake, but the therapeutic approach can be redirected from sulfatase inhibition to competitive sulfation enhancement. Rather than preserving existing 6-O-sulfation patterns through SULF1/2 inhibition, this strategy leverages the competitive substrate dynamics between different sulfotransferases to create protective HS modification patterns. The 3-O-sulfotra
**Molecular Mechanism and Rationale**
The pathological spread of tau protein aggregates represents a central mechanism underlying the progression of Alzheimer's disease and related tauopathies. Recent advances have elucidated the critical role of heparan sulfate proteoglycans (HSPGs) in facilitating the uptake of extracellular tau species by neurons, establishing these cell surface receptors as compelling therapeutic targets. The molecular mechanism centers on the interaction between pathologic
