Pneumonia models and innate immunity to respiratory bacterial pathogens

Abstract

Preclinical sepsis models have been used for decades to study the pathophysiologic processes during sepsis and shock. Although these studies revealed promising immunomodulating agents for the treatment of sepsis, clinical trials evaluating the efficacy of these new agents in patients with sepsis were disappointing. The main reason for this unsatisfactory experience might be that unlike the clinical situation, most of these preclinical models are devoid of a localized infectious source from which the infection disseminates. Studies on the effects of several immunomodulating strategies have demonstrated strikingly opposite results when sepsis models with a more natural route of infection, such as pneumonia, were used. In this review, we will give insights into pneumonia models and discuss results and differences in the innate immune responses during distinct pulmonary infection models.

Statistics

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?

  • Resident alveolar macrophages are considered the most important first line of defense against respiratory pneumococcal infections.

    “Among host innate immune players, resident alveolar macrophages (AMs) are considered to be the most important first line of defense against respiratory pneumococcal infections (13), through their high phagocytic capacity (14–16).”

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.
