Lipid Transport

Lipid Transport enters the Adult Cognitive Disease corpus through the work of Daniel Michaelson (submission 86), and is indexed here as one of the concepts that submission puts to work.

The argument it belongs to

Daniel Michaelson's submission is summarised in this corpus as:

The pathogenicity of ApoE4 is driven by its hypolipidation -- a structural inability to accept lipids from the ABCA1 transporter due to a pathological domain interaction creating a compact 'molten globule' conformation. This lipid deficit directly destabilizes endolysosomal membrane composition, causing v-ATPase disassembly, lysosomal acidification failure, and autophagic collapse.

The source paper puts the concept to work directly:

The myriad of mechanisms underlying the effects of apoE including lipid transport and enhanced response to injury and stress place apoE as an important factor in inflammation and neurodegeneration111.

Where it sits

The submission scores against the framework's convergence nodes as: ApoE4 hub 10 · endosomal nexus 9 · cytoskeletal collapse 1 · compensatory paradigm 1.
