Heparan sulfate modified proteins affect cellular processes central to neurodegeneration and modulate presenilin
Heparan sulfate proteoglycans (HSPGs) are implicated in Alzheimer's disease (AD) pathogenesis. Modulating HSPG synthesis impacts pathways like autophagy and lipid metabolism, offering potential therapeutic targets for AD.
Area of Science:
- Neuroscience
- Genetics
- Molecular Biology
Background:
- Mutations in presenilin-1 (PSEN1) are a primary cause of early-onset familial Alzheimer's disease (AD).
- A protective APOE variant, APOE3 Christchurch, shows reduced binding to heparan sulfate (HS), suggesting a role for HS in AD pathology.
Conclusions:
- HSPGs play a direct role in Alzheimer's disease pathogenesis.
- Targeting HSPG synthesis may offer a novel therapeutic strategy for AD.
- The findings highlight conserved mechanisms of HSPG influence on AD-related pathways.
