How does glial lipid efflux mechanistically reduce tau pathology and neurodegeneration?

While LXR agonist treatment and Abca1 overexpression both increase lipid efflux and reduce tau pathology, the causal mechanisms connecting improved lipid metabolism to reduced tau-mediated neurodegeneration are not established. This represents a critical knowledge gap for therapeutic development.
