Abstract

Key Points: Heme and iron induce macrophage phenotypic switching toward an M1 proinflammatory phenotype. By scavenging free heme, hemopexin reverts heme-induced proinflammatory activation of macrophages in a mouse model of sickle cell disease.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Iron present in heme can stimulate production of ROS and pro-inflammatory cytokines such as TNF, IL-1ß, and IL-6.

    “In this context, iron present in heme can stimulate the production of ROS and of pro-inflammatory cytokines such as TNF, IL-1ß, and IL-6 [241].”
  • The iron species used and route of uptake are not crucial for macrophage polarization outcome, as heme and simple iron chelates can also induce a phenotypical shift.

    “Vinchi and colleagues showed that the iron species used and the route of uptake is not crucial for the outcome of macrophage polarization, as evidenced by the fact that also even heme and simple iron chelates can induce a phenotypical shift in macrophages [215].”

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.
