Abstract

Macrophages play an important role in structural cardiac remodeling and the transition to heart failure following myocardial infarction (MI). Previous research has focused on the impact of blood-derived monocytes on cardiac repair. Here we examined the contribution of resident cavity macrophages located in the pericardial space adjacent to the site of injury. We found that disruption of the pericardial cavity accelerated maladaptive post-MI cardiac remodeling. Gata6+ macrophages in mouse pericardial fluid contributed to the reparative immune response. Following experimental MI, these macrophages invaded the epicardium and lost Gata6 expression but continued to perform anti-fibrotic functions. Loss of this specialized macrophage population enhanced interstitial fibrosis after ischemic injury. Gata6+ macrophages were present in human pericardial fluid, supporting the notion that this reparative function is relevant in human disease. Our findings uncover an immune cardioprotective role for the pericardial tissue compartment and argue for the reevaluation of surgical procedures that remove the pericardium.

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

  • The αv-containing integrins αvβ1, αvβ3, αvβ5, αvβ6, and αvβ8 bind to the latency-associated peptide (LAP) of TGF-β1.

    “the integrins αvβ1, αvβ3, αvβ5, αvβ6 and αvβ8 have all been shown to bind to an N-terminal fragment of the TGFβ1 gene product called the latency associated peptide (LAP)”

    From Fibrosis: from mechanisms to medicines (2020) · cites this paper as [89]

  • LAP normally forms a noncovalent latent complex with active TGF-β, preventing TGF-β from binding its receptors and inducing biological effects.

    “which normally forms a noncovalent complex (latent complex) with the active cytokine, preventing TGF-β from binding to its cognate receptors and inducing biological effects89–93”

  • Small molecule inhibitors of αvβ1 have an anti-fibrotic effect in models of lung and liver fibrosis.

    “recent studies demonstrating an anti-fibrotic effect of αvβ1 blockade in models of lung and liver fibrosis89”

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.
