Tubercle bacilli rely on a type VII army for pathogenicity

Abstract

Mycobacteria, such as the major human pathogen Mycobacterium tuberculosis, have a highly unusual and characteristic diderm cell envelope that protects them against harmful conditions. Protein secretion across this hydrophobic barrier requires specialized secretion systems. Recently, a type VII secretion (T7S) pathway has been identified that fulfills this function. Pathogenic mycobacteria have up to five different T7S systems, some of which play a crucial role in virulence. The interactions between secreted substrates and host molecules are only starting to become clear and will help in furthering our understanding of the persistence of these enigmatic pathogens. In this review, we discuss current knowledge on the role of T7S systems in mycobacterial virulence.

Recomputing p-values needs the paper’s full text.

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?

  • A number of secreted effectors, including EsxA (ESAT-6), EsxB (CFP-10), EspA, EspC, and PE/PPE proteins, have been suggested to intervene in host cellular and immune signaling pathways.

    “Indeed, a number of secreted effectors, including EsxA (ESAT-6), EsxB (CFP-10), and ESX-1 secretion-associated proteins (Esp), such as EspA or EspC, as well as proteins that carry the characteristic N-terminal motifs Pro-Glu (PE) and Pro-Pro-Glu (PPE), have been suggested to intervene in host cellular and immune signaling pathways (11,24,25).”

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.
