AMYLOID BETA PEPTIDES AS ANTIMICROBIAL PEPTIDES: RELEVANCE FOR ALZHEIMER’S DISEASE?
Bibliographic record
Abstract
Amyloid β (Aβ) peptides generated by the amyloidogenic pathway of amyloid precursor protein (APP) processing contribute significantly to neurological degeneration characteristic of Alzheimer’s disease (AD). Their precise role, whether it be direct or the indirect target of an inflammatory response, has been a subject of considerable debate. Data published in the last 6 years by three different groups have added a new twist by revealing that Aβ peptides could act as antimicrobial peptides (AMP). These observations are of significance with respect to the notion that pathogens may be important contributors to the development of AD, particularly in the case of Herpes simplex virus (HSV) infection which often resides in the same cerebral sites where AD arises. Our recent data support the interpretation that Aβ peptides behave as AMP, with an emphasis on studies concerning HSV-1 and a putative molecular mechanism that suggests that interactions between Aβ peptides and the HSV-1 lead to impairment of HSV-1 infectivity by preventing the virus from fusing with the plasma membrane.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
