Release of mycobacterial antigens

Abstract

Summary: Mycobacterium tuberculosis has evolved from a Mycobacterium canettii‐like progenitor pool into one of the most successful and widespread human pathogens. The pathogenicity of M. tuberculosis is linked to its ability to secrete/export/release selected mycobacterial proteins, and it is also established that active release of mycobacterial antigens is a prerequisite for strong immune recognition. Recent research has enabled mycobacterial secretion systems and vesicle‐based release of mycobacterial antigens to be elucidated, which together with host‐related specificities constitute key variables that determine the outcome of infection. Here, we discuss recently discovered, novel aspects on the nature and the regulation of antigen release of the tuberculosis agent with particular emphasis on the biological characterization of mycobacteria‐specific ESX/type VII secretion systems and their secreted proteins, belonging to the Esx, PE, and PPE categories. The importance of specific mycobacterial antigen release is probably best exemplified by the striking differences observed between the cellular events during infection with the ESX‐1‐deficient, attenuated Mycobacterium bovis BCG compared to the virulent M. tuberculosis, which are clearly important for design of more specific diagnostics and more efficient vaccines.

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

  • ESX-1, ESX-3, and ESX-5 all contribute to virulence of M. tuberculosis, although exact molecular functions often remain vague; studies with different mycobacterial species may show species-specific differences.

    “In contrast, for ESX-1, ESX-3, and ESX-5, recent research has determined that they all contribute to virulence of M. tuberculosis, although the insights into the exact molecular functions often remain vague; also, because many studies have been undertaken with different mycobacterial species (M.tuberculosis, M. marinum, M. abscessus, and/or Mycobacterium smegmatis), which may show some species-”

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.
