Lipid peroxidation cascade at synapse

Lipid Peroxidation Cascade At Synapse enters the Adult Cognitive Disease corpus through the work of Christopher Ramsden (submission 167), and is indexed here as one of the concepts that submission puts to work.

The argument it belongs to

Christopher Ramsden's submission is summarised in this corpus as:

ApoE peroxidation and the formation of crosslinked ApoE–ApoE-receptor complexes are the fundamental molecular events underlying sporadic Alzheimer's disease. Peroxidized ApoE (Px-ApoE) — its lipid cargo and receptor-binding domain left vulnerable by ApoE4's lack of cysteines at residues 112/158 — adducts and crosslinks ApoE receptors, (1) impairing receptor-dependent lipid delivery, (2) disrupting the Reelin–ApoE-receptor signaling cascades that shape and protect synapses, and (3) trapping Px-ApoE outside neurons as a nidus for amyloid-beta oligomerization. Aβ plaques and gliosis are initially protective responses that become damaging with chronic exposure.

Where it sits

The submission scores against the framework's convergence nodes as: neuroimmune interface 8 · ApoE4 hub 6 · cytoskeletal collapse 4 · compensatory paradigm 3 · transcriptional / epigenetic 3 · endosomal nexus 2.

Its declared subject matter: ApoE-peroxidation, lipid-peroxidation, Reelin-signaling, ApoER2, receptor-crosslinking, synaptic-dysfunction, ApoE4, neuritic-plaques.

Named by the same submission

8 other concepts enter the corpus through the same paper, so they cover adjacent ground: ApoE4 structural vulnerability · Immune-pathogen interaction model · Multi-cellular pathology · Neurovascular dysfunction as initiating event · Peroxidized ApoE as proximate cause · Post-translational modification dysregulation · Reelin-ApoE receptor axis disruption · Chronic Excitatory Insufficiency.

Assembled from the corpus rather than written: the summary is quoted from the submission that named it; the node scores are read from its dossier. It has not yet been expanded into an article.
