This hypothesis proposes that selective LXRβ agonism primarily functions through transcriptional upregulation of ABCA1 (ATP-binding cassette transporter A1) to facilitate cholesterol efflux from activated microglia and prevent pathological lipid accumulation in neuroinflammatory conditions. LXRβ activation would induce ABCA1 expression, creating a robust cholesterol export mechanism that reduces intracellular cholesterol burden in microglia while simultaneously promoting the formation of properl
## Mechanistic Overview
HDL/apoE Particle Remodeling as a Therapeutic Switch for CAA Prevention starts from the claim that modulating ABCA1 within the disease context of neurodegeneration can redirect a disease-relevant process. The original description reads: "**Molecular Mechanism and Rationale** The dual role of apolipoprotein E (apoE) in amyloid-β (Aβ) clearance represents a critical therapeutic target for cerebral amyloid angiopathy (CAA) prevention. ApoE exists in multiple lipidation state
