Abstract

The transport of iron by RAW264.7 macrophage cell lines transfected with either Nramp1Gly169 (resistant) or Nramp1Asp169 (susceptible) alleles was assessed. We found no difference between resistant and susceptible cells in the rate of Fe import or export when Fe transport was measured in intact cells. In contrast, the rate of Fe import by latex-bead phagosomes isolated from resistant cells was more than double the rate by latex-bead phagosomes from susceptible cells. Similarly, phagosomes isolated from resistant cells that had been pre-labeled with 55Fe-citrate before phagocytosis contained up to four times as much Fe as the corresponding phagosomes from susceptible cells. Phagocytosis of Mycobacterium avium was accompanied by an increase in the production of hydroxyl radicals by Nramp1Gly169-transfected macrophages but not by macrophages transfected with the susceptible allele. These results are consistent with the hypothesis that Nramp1 functions to transport Fe into the bacterium-containing phagosome where it serves as a catalyst for the Haber-Weiss reaction, which accounts for the increased capacity of these cells to limit mycobacterial growth.

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.
