Abstract

Mycobacterium tuberculosis owes its high pathogenic potential to its ability to evade host immune responses and thrive inside the macrophage. The outcome of infection is largely determined by the cellular response comprising a multitude of molecular events. The complexity and inter-relatedness in the processes makes it essential to adopt systems approaches to study them. In this work, we construct a comprehensive network of infection-related processes in a human macrophage comprising 1888 proteins and 14,016 interactions. We then compute response networks based on available gene expression profiles corresponding to states of health, disease and drug treatment. We use a novel formulation for mining response networks that has led to identifying highest activities in the cell. Highest activity paths provide mechanistic insights into pathogenesis and response to treatment. The approach used here serves as a generic framework for mining dynamic changes in genome-scale protein interaction networks.

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

  • The fight of the host against the pathogen in M. tuberculosis infection involves several levels including containment of the microbe, generation of radicals and a hostile acidic environment, deprivation from essential nutrients, formation of anti-mycobacterial peptides and cytokines, and cell damage and suicidal activities of macrophages and PMNs such as autophagy, necroptosis, or efferocytosis to

    “the fight of the host against the pathogen in M. tuberculosis infection involves several levels including containment of the microbe, generation of radicals and a hostile, acidic environment, deprivation from essential nutrients, formation of anti-mycobacterial peptides and cytokines which strengthen host responses by attracting other immune cells, down to cell damage and suicidal activities of MO”

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.
