Original title: Immunology of Acute and Chronic Wound Healing
When skin is wounded, immune cells help clean it and support tissue repair. If the immune response stays active too long, inflammation can persist and healing may slow down. Chronic wounds can contain many pro-inflammatory macrophagesImmune cells that can help clear material from a wound and also influence inflammation., inflammatory signals, tissue-breaking enzymes, and reactive oxygen species; bacterial biofilms can add to the problem. This review describes how innate and adaptive immunityThe part of the immune system that learns to recognize particular threats. affect wounds and discusses treatments that try to adjust immune activity.
Imagine cleaning a cut on your hand while trying to let it mend. The cleanup is useful, but if it never winds down, the area stays irritated; germs can make that harder to stop. In this paper, the cleanup stands for the immune response, and the trouble that keeps it going stands for the inflammation and bacterial growth described in chronic wounds.
Chronic wounds can be hard to heal and place a burden on patients and healthcare systems. Understanding how immune cells and inflammatory signals affect wounds may help researchers develop treatments that guide the immune response toward healing.
The abstract describes a review of wound immunity and immunomodulatory strategies, but it does not report clinical trial results or show that any particular treatment improves healing in patients. It also does not specify how the reviewed strategies compare in effectiveness or safety.
