Resolution of inflammation: the beginning programs the end

Serhan, Charles N, Savill, John·2005·Nature Immunology

Abstract

Acute inflammation normally resolves by mechanisms that have remained somewhat elusive. Emerging evidence now suggests that an active, coordinated program of resolution initiates in the first few hours after an inflammatory response begins. After entering tissues, granulocytes promote the switch of arachidonic acid-derived prostaglandins and leukotrienes to lipoxins, which initiate the termination sequence. Neutrophil recruitment thus ceases and programmed death by apoptosis is engaged. These events coincide with the biosynthesis, from omega-3 polyunsaturated fatty acids, of resolvins and protectins, which critically shorten the period of neutrophil infiltration by initiating apoptosis. Consequently, apoptotic neutrophils undergo phagocytosis by macrophages, leading to neutrophil clearance and release of anti-inflammatory and reparative cytokines such as transforming growth factor-beta1. The anti-inflammatory program ends with the departure of macrophages through the lymphatics. Understanding these and further details of the mechanism required for inflammation resolution may underpin the development of drugs that can resolve inflammatory processes in directed and controlled ways.

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

  • Attenuating inflammation itself might interfere with successful resolution, since the process of resolution is initiated already very early during the inflammatory process.

    “In conclusion, attenuating inflammation itself might also interfere with successful resolution, since the process of resolution is initiated already very early during the inflammatory process.441”

  • Excessive fibrotic response is a direct result of failed resolution of sterile inflammation, with impaired phagocytosis of injured hepatocytes enabling exposure of quiescent stellate cells to fibrogenic mito-DAMPs.

    “Conceptually, results of our study support the idea that excessive fibrotic response is a direct result of a “failed” resolution of sterile inflammation35, with impaired phagocytosis of injured hepatocytes enabling exposure of quiescent stellate cells to fibrogenic mito-DAMPs.”
  • PPARγ is important to shape an anti-inflammatory macrophage phenotype and appears crucial for dampening inflammation.

    “Thus, PPAR␥ is important to shape an anti-inflammatory macrophage phenotype and appears crucial for dampening inflammation (15).”

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.
