Abstract

Characteristic of both chronic wounds and acute wounds that fail to heal are excessive leukocytosis and reduced matrix deposition. Estrogen is a major regulator of wound repair that can reverse age-related impaired wound healing in human and animal models, characterized by a dampened inflammatory response and increased matrix deposited at the wound site. Macrophage migration inhibitory factor (MIF) is a candidate proinflammatory cytokine involved in the hormonal regulation of inflammation. We demonstrate that MIF is upregulated in a distinct spatial and temporal pattern during wound healing and its expression is markedly elevated in wounds of estrogen-deficient mice as compared with intact animals. Wound-healing studies in mice rendered null for the MIF gene have demonstrated that in the absence of MIF, the excessive inflammation and delayed-healing phenotype associated with reduced estrogen is reversed. Moreover, in vitro assays have shown a striking estrogen-mediated decrease in MIF production by activated murine macrophages, a process involving the estrogen receptor. We suggest that estrogen inhibits the local inflammatory response by downregulating MIF, suggesting a specific target for future therapeutic intervention in impaired wound-healing states.

  • Topical application of estrogens or ER agonists in aged females and males can improve healing, partially due to reduced MIF and activation of keratinocytes.

    “Topical application of estrogens or ER agonists in both aged females and males can improve healing, which may be partially due to the reduced expression of macrophage migration inhibitory factor (MIF) and activation of keratinocytes [145–147].”

    From Transition from inflammation to proliferation: a critical step during wound healing (2016) · cites this paper as [146]

    The Introduction reports improved healing with topical estrogen in elderly women and men, and the Discussion proposes ER-mediated reduction of MIF as a mechanism (page numbers unavailable). The paper shows ER agonists inhibiting MIF expression in cells, but does not show that topical ER agonists improve healing in aged people or that keratinocyte activation explains the benefit; it reports MIF localization to keratinocytes instead.

  • Estrogen is a positive effector in wound healing.

    “estrogen has been demonstrated as a positive effector in wound healing.”
  • Estrogen is important to wound healing, and its deficiency delays or impairs wound healing.

    “Numerous studies have shown that estrogen is important to wound healing, and its deficiency delays or impairs wound healing29–33.”

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.
