Abstract

Sickle cell trait (HbAS) is the best-characterized genetic polymorphism known to protect against falciparum malaria. Although the protective effect of HbAS against malaria is well known, the mechanism(s) of protection remain unclear. A number of biochemical and immune-mediated mechanisms have been proposed, and it is likely that multiple complex mechanisms are responsible for the observed protection. Increased evidence for an immune component of protection as well as novel mechanisms, such as enhanced tolerance to disease mediated by HO-1 and reduced parasitic growth due to translocation of host micro-RNA into the parasite, have recently been described. A better understanding of relevant mechanisms will provide valuable insight into the host-parasite relationship, including the role of the host immune system in protection against malaria.

  • In sickle cell hemoglobin, the balance between damaging prooxidative molecules such as free heme or iron and antioxidative factors such as carbon monoxide and bilirubin is shifted towards cytoprotection.

    “As a consequence, the balance between damaging prooxidative molecules such as free heme or iron and antioxidative factors such as carbon monoxide (CO) and bilirubin is shifted towards cytoprotection (Cholera et al., 2008;Ferreira et al., 2011;Gong et al., 2013;Jeney et al., 2014).”

    From Iron in infection and immunity (2020) · cites this paper as Gong et al., 2013

    The Background section (‘Modulation of immunopathogenesis’; page not provided) reports that sickle haemoglobin may induce HO-1, reducing cytotoxic free haem and tissue damage in a mouse model of cerebral malaria. The Conclusions likewise describe HO-1–mediated tolerance as a possibility. Our copy does not state that carbon monoxide and bilirubin shift a balance against free haem or iron toward cytoprotection, and the cited mechanism is more tentative than the claim suggests.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
