A Reservoir of Mature Cavity Macrophages that Can Rapidly Invade Visceral Organs to Affect Tissue Repair

Abstract

A key feature of inflammation is the timely recruitment of leukocytes, including monocytes, from blood into tissues, the latter maturing into macrophages over a period of 2-3 days. Using multi-channel spinning disk microscopy, we identified a rapid pathway of macrophage recruitment into an injured organ via a non-vascular route requiring no maturation from monocytes. In response to a sterile injury in liver, a reservoir of fully mature F4/80(hi)GATA6(+) peritoneal cavity macrophages rapidly invaded into afflicted tissue via direct recruitment across the mesothelium. The invasion was dependent on CD44 and DAMP molecule ATP and resulted in rapid replication and switching of macrophage toward an alternatively activated phenotype. These macrophages dismantled the nuclei of necrotic cells releasing DNA and forming a cover across the injury site. Rapid invasion of mature macrophages from body cavity with capacity for induction of reparative phenotype may impact altered tissues ranging from trauma to infections to cancer. VIDEO ABSTRACT.

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

  • Nearly all TGF-β1 is secreted and bound to the ECM in a latent form, and therefore the majority of regulation of TGF-β function during fibrosis depends on site-specific regulation of TGF-β activation rather than synthesis or secretion.

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.
