Induction of Fas Mediated Caspase-8 Independent Apoptosis in Immune Cells by Armigeres subalbatus Saliva
Bibliographic record
Abstract
BACKGROUND: It is widely recognized that the introduction of saliva of bloodsucking arthropods at the site of pathogen transmission might play a central role in vector-borne infections. However, how the interaction between salivary components and the host immune system takes place and which physiological processes this leads to has yet to be investigated. Armigeres subalbatus is one of the prominent types of mosquitoes involved in the transmission of parasitic and viral diseases in humans and animals. METHODOLOGY/PRINCIPAL FINDINGS: Using murine peritoneal macrophages and lymphocytes, and human peripheral mononuclear cells (PBMCs), this study shows that saliva of the female Ar. subalbatus induces apoptosis via interaction with the Fas receptor within a few hours but without activating caspase-8. The process further activates downstream p38 MAPK signaling, a cascade that leads to the induction of apoptosis in capase-3 dependent manner. We further illustrate that Ar. subalbatus saliva suppresses proinflammatory cytokines without changing IL-10 levels, which might happen as a result of apoptosis. CONCLUSIONS: Our study shows for the first time that saliva-induced apoptosis is the leading phenomenon exerted by Ar.subalbatus that impede immune cells leading to the suppression of their effecter mechanism.

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.
