This hypothesis proposes that upregulating SULF1/SULF2 sulfatase activity provides dual neuroprotection by simultaneously blocking extracellular tau uptake and preserving intracellular cholinergic function. The molecular mechanism centers on SULF1/SULF2's ability to remove 6-O-sulfate groups from heparan sulfate proteoglycan chains, disrupting the high-affinity binding sites required for pathological tau aggregate uptake by cholinergic neurons. Cholinergic neurons in the nucleus basalis of Meyne
**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
