Abstract

The magnitude and duration of acute inflammation are controlled by active resolution programs involving specialized proresolving mediators (SPMs; resolvins and maresins) and microRNAs (miRNAs). Here, we report that miR-466l was temporally regulated in murine exudate-infiltrating leukocytes. Neutrophil miR-466l overexpression in vivo promoted initiation of inflammation that anteceded macrophage expression of this miRNA, which accelerated resolution when overexpressed. In macrophages, miR-466l overexpression increased prostanoids and SPMs (e.g., resolvin D1 [RvD1] and RvD5), which enhanced resolution. RvD1, RvD2, maresin 1 (MaR1), and apoptotic neutrophils reduced miR-466l expression within human macrophages, a feedback regulation that most likely prepares for homeostasis. miR-466l was upregulated in peripheral blood of sepsis patients, and its increase correlated with nonsurvival from sepsis. SPMs and miR-466l regulated transcription factors activator protein 1 and nuclear factor κB1 in miRNA biogenesis. These results demonstrate pivotal roles for SPMs and miR-466l in dynamic leukocyte plasticity during resolution of acute inflammatory responses.

  • miR-466l is upregulated in peripheral blood of sepsis patients and its levels correlate with risk of death.

  • In a murine model, during the inflammatory response, miR-466l is first overexpressed in neutrophils, acting proinflammatory, and then overexpressed in macrophages, leading to increase in prostanoids and specialized proresolving mediators (RvD1, RvD5).

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.
