Human IRGM Induces Autophagy to Eliminate Intracellular Mycobacteria

Singh, Sudha B., Davis, Alexander S., Taylor, Gregory A., Deretic, Vojo·2006·Science

Abstract

Immunity-related p47 guanosine triphosphatases (IRG) play a role in defense against intracellular pathogens. We found that the murine Irgm1 (LRG-47) guanosine triphosphatase induced autophagy and generated large autolysosomal organelles as a mechanism for the elimination of intracellular Mycobacterium tuberculosis . We also identified a function for a human IRG protein in the control of intracellular pathogens and report that the human Irgm1 ortholog, IRGM, plays a role in autophagy and in the reduction of intracellular bacillary load.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

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

  • Infection-induced autophagy by IFN-γ activation or by starvation requires activation of the small GTPase LRG47 (IRGM in humans).

    “Infection-induced autophagy by IFN-γ activation or by starvation requires activation of the small GTPase LRG47 (IRGM in humans) (76, 77).”

  • Functional IRGM1 dampens IL1B maturation by interfering in NLRP3 inflammasome assembly.

    “Recently, it has been shown that functional IRGM1 (immunity‐related GTPase family M member 1), a Crohn disease risk factor (Parkes et al, 2007) which participates in the autophagy‐dependent elimination of intracellular pathogens (Singh et al, 2006; Kumar et al, 2020), dampens IL1B maturation by interfering in NRLP3 inflammasome assembly.”

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.
