Inflammation and wound healing: the role of the macrophage

Open access
Koh, Timothy J., DiPietro, Luisa Ann·2011·Expert Reviews in Molecular Medicine

Abstract

The macrophage is a prominent inflammatory cell in wounds, but its role in healing remains incompletely understood. Macrophages have many functions in wounds, including host defence, the promotion and resolution of inflammation, the removal of apoptotic cells, and the support of cell proliferation and tissue restoration following injury. Recent studies suggest that macrophages exist in several different phenotypic states within the healing wound and that the influence of these cells on each stage of repair varies with the specific phenotype. Although the macrophage is beneficial to the repair of normally healing wounds, this pleotropic cell type may promote excessive inflammation or fibrosis under certain circumstances. Emerging evidence suggests that macrophage dysfunction is a component of the pathogenesis of nonhealing and poorly healing wounds. As a result of advances in the understanding of this multifunctional cell, the macrophage continues to be an attractive therapeutic target, both to reduce fibrosis and scarring, and to improve healing of chronic wounds.

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

  • Macrophages belong to active innate immune cells and provide important responses following interaction with a biomaterial, including proteins, interleukins, chemokines, and immunomodulatory factors that steer the environment toward a pro- or anti-inflammatory state.

    “Macrophages belong to the group of active innate immune cells and provide some of the most important responses following the interaction with a biomaterial. These responses include a number of proteins, interleukins, chemokines, and immunomodulatory factors that steer the environment toward either a pro‐ or anti‐inflammatory state.[ 64 ]”

  • Macrophages regulate ECM content and remodeling by secretion of proteases and inhibitors, such as MMPs and TIMPs.

    “In the final phase of healing, macrophages also regulate ECM content and remodeling by secretion of proteases and their inhibitors, such as matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinase (TIMPs) [75–77].”

    From Transition from inflammation to proliferation: a critical step during wound healing (2016) · cites this paper as [75]

    The section on angiogenesis, fibroblast proliferation and ECM synthesis says macrophages produce proteases and inhibitors that influence ECM content and remodeling. It does not identify MMPs or TIMPs. The section on macrophage phenotypes describes their role in the final resolution phase as an open question, so the source does not establish the claim specifically for that phase. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • M2 macrophages consistently express scavenger and mannose receptors (CD206), release anti-inflammatory cytokines such as IL-10, display high iron export aiding tissue remodeling, and encompass subsets including wound healing and regulatory macrophages.

    “M2 macrophages consistently express scavenger and mannose receptors (CD206), release anti-inflammatory cytokines such as IL-10 [19], display a high level of iron export aiding in tissue remodeling [18] and encompass a range of different subsets (i.e., M2a, M2b, M2c) including 'wound healing' and 'regulatory macrophages' [20].”
  • Macrophages are recognized as the most long-lived and central cell population in dermal wound healing, largely through production of cytokines, growth factors, and MMPs.

    “Macrophages, however, have been recognized as the most long-lived and central cell population that plays a role in dermal wound healing largely through the production of the cytokines, growth factors, and MMPs described above [93,103,104].”
  • The key cells of the inflammatory phase are neutrophils and monocytes/macrophages.

    “The key cells of the inflammatory phase are neutrophils and monocytes/macrophages [2, 6, 45].”

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.
