Microglial senescence as AD trigger

Microglial Senescence As Ad Trigger enters the Adult Cognitive Disease corpus through the work of Soghra Bagheri (submission 69), and is indexed here as one of the concepts that submission puts to work.

The argument it belongs to

Soghra Bagheri's submission is summarised in this corpus as:

AD follows a defined sequence of events: aging microglia lose phagocytic capacity after approximately seven decades, allowing uncleared amyloid-beta to dimerize and form calcium channels in neuronal membranes. This calcium influx triggers tau hyperphosphorylation, and when combined with infection by pathogens that breach the aging blood-brain barrier, leads to plaque and tangle formation in a predictable pattern.

Where it sits

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

Its declared subject matter: microglial-aging, calcium-signaling, infection-hypothesis, blood-brain-barrier, tangle-threshold, immunosenescence, copper-metabolism, aging.

Named by the same submission

4 other concepts enter the corpus through the same paper, so they cover adjacent ground: Age-dependent threshold model · Calcium-mediated tauopathy · Infection as co-factor in neurodegeneration · Cellular Senescence.

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.
