Cytokine-mediated tissue repair

Cytokine-mediated tissue repair is a complex biological process where immune signaling molecules coordinate the restoration of tissue integrity after injury (PMID: 29463708). Key cytokines such as Interleukin-22 (IL-22) promote epithelial regeneration and barrier function, while Interleukin-4 (IL-4) and Interleukin-13 (IL-13) drive the activation of fibroblasts and macrophages to facilitate wound closure (PMID: 24610278, PMID: 30105162). Transforming growth factor-beta (TGF-beta) serves as a master regulator of extracellular matrix deposition, which is essential for structural repair but can lead to pathological fibrosis if dysregulated (PMID: 22412984). Therapeutic agents like Dupilumab or Nintedanib interact with specific components of these pathways to either suppress pathological scarring or enhance healing in chronic conditions (PMID: 31034782). Because this term describes a broad physiological mechanism involving multiple distinct proteins and pathways rather than a single discrete molecule, it is classified as a biological process rather than a specific therapeutic target.

Drugs modulate this process by agonizing or antagonizing specific cytokines (e.g., IL-4, IL-13, TGF-beta, IL-22) or their receptors to balance regenerative versus fibrotic responses and restore tissue homeostasis.
