Erythrocyte variants and the nature of their malaria protective effect
Bibliographic record
Abstract
The malaria threat to global health is exacerbated by widespread drug resistance in the Plasmodium parasite and its insect vector, and the lack of an efficacious vaccine. Infection with Plasmodium parasites can cause a wide spectrum of pathologies, from a transient mild form of anaemia to a severe and rapidly fatal cerebral disease. Epidemiological studies in humans and experiments in animal models have shown that genetic factors play a key role in the onset, progression, type of disease developed and ultimate outcome of malaria. The protective effect of polymorphic variants in erythrocyte-specific structural proteins or metabolic enzymes against the blood-stage of the disease is one of the clearest illustrations of this genetic modulation, and has suggested co-evolution of the Plasmodium parasite with its human host in areas of endemic disease. Here, we present a brief overview of erythrocyte polymorphisms with biological relevance to malaria pathogenesis, and current work on the mechanism(s) by which these mediate their protective effect. The recent addition of erythrocyte pyruvate kinase to this group of protective genes will also be discussed.

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.
