Abstract

The murine Bcg/Ity/Lsh locus determines the susceptibilities of inbred strains to infection with unrelated intracellular parasites, such as Mycobacterium bovis, Salmonella typhimurium, and Leishmania donovani. A candidate for Bcg/Ity/Lsh, designated Nramp1, has been recently identified and shown to encode a novel integral membrane protein that is expressed exclusively in professional phagocytes but whose function remains unknown. In inbred strains, the susceptibility to infection is associated with a single glycine-to-aspartic acid substitution at position 169 (G169D) in the predicted TM4 of the protein. To confirm the candidacy of Nramp1 as Bcg/Ity/Lsh and to determine the importance of the G169D mutation on Nramp1 function, we constructed transgenic mice in which the G169 allele of Nramp1 was transferred onto the background of a homozygous D169 allele. These transgenic mice were analyzed for their sensitivity to infections under the control of Bcg/Ity/Lsh. The transgene constructed for these studies contained the entire Nramp1G169 gene together with approximately 5 kb of sequences upstream of the transcription initiation site of this gene. We observed that these sequences were sufficient to direct Nramp1G169 expression in transgenic macrophages, resulting in the appearance of a mature protein of 90 to 100 kDa over a background of Nramp1G169 characterized by the complete absence of the mature Nramp1 polypeptide. The appearance of the Nramp1G169-encoded protein in transgenic macrophages was concomitant with the emergence of resistance to infection by M. bovis BCG, as measured by the extent of bacteria] replication in the spleen, and by S. typhimurium, as measured by survival after an intravenous challenge. The gain of function detected in transgenic Nramp1G169 animals establishes unambiguously that Nramp1 and Bcg/Ity/Lsh are allelic.

  • Slc11a1 coding rather than regulatory region variation is relevant to a broader spectrum of intracellular infectious agents including Francisella tularensis and S. Typhimurium.

    “coding rather than in the regulatory region of Slc11a1, which is relevant to a broader spectrum of intracellular infectious agents also including Francisella tularensis and S. Typhimurium (Govoni et al., 1996;Kovarova et al., 2000;Vidal et al., 1995).”

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.
