Description
The inflammatory response to wounding is a fundamental biological process that protects against infection and initiates tissue repair. GO:0106014, regulation of inflammatory response to wounding, encompasses any process that modulates the frequency, rate, or extent of this response [1, 8]. This regulation is critical for balancing effective pathogen clearance with avoidance of excessive tissue damage. Dysregulation can lead to chronic non-healing wounds, fibrosis, or systemic inflammatory conditions [2, 8]. Understanding the molecular players and signaling pathways that control this process is essential for developing targeted therapies. Recent multi-omic studies have revealed temporal dynamics of inflammatory mediators after tissue injury, highlighting the complexity of this regulatory network. Key cytokines such as IL-6 and IL-17 family members are central nodes in this regulation [3, 4]. Macrophages act as pivotal regulators, switching phenotypes to promote resolution of inflammation and tissue repair. This article synthesizes current knowledge on the mechanisms, genes, and research methods relevant to GO:0106014, providing a resource for researchers studying wound inflammation.

What Is GO:0106014?
GO:0106014 is defined as any process that modulates the frequency, rate, or extent of the inflammatory response to wounding. In other words, it includes all molecular and cellular events that control how strongly, how long, and how efficiently the body reacts to tissue injury with inflammation. This regulation ensures that the inflammatory response is appropriate for the type and severity of the wound, and that it resolves in a timely manner to allow healing [1, 8].
Why Is regulation of inflammatory response to wounding Important in Cell Biology?
Regulation of the inflammatory response to wounding is critical for maintaining tissue homeostasis and preventing chronic disease. Excessive or prolonged inflammation can lead to tissue damage, fibrosis, and impaired healing, while insufficient inflammation increases infection risk. Understanding this process is essential for developing therapies for chronic wounds, inflammatory skin diseases, and systemic inflammatory conditions [2, 8]. Moreover, species differences in inflammatory responses highlight the need for human-relevant models to translate findings into clinical applications.
• Chronic wounds affect millions worldwide, and dysregulated inflammation is a key driver.
• Inflammatory mediators such as IL-6 and IL-17 are therapeutic targets in autoimmune and inflammatory diseases [3, 4].
• Macrophage polarization is a critical determinant of wound healing outcomes.
• Mouse models often fail to replicate human inflammatory responses, necessitating human cell-based studies.
• Exercise-induced multi-omic changes reveal systemic regulation of inflammation.
• Perivascular adipose tissue inflammation contributes to vascular remodeling and cardiovascular disease.
• Tendinopathy involves inflammatory dysregulation that impairs healing.
• CRISPR screening can identify novel regulators of wound inflammation [1, 5].
• Targeting inflammatory regulation can improve outcomes in diabetic wound healing.
• Understanding temporal dynamics of inflammation aids in designing optimal therapeutic windows.
What Happens During regulation of inflammatory response to wounding?
Initiation of inflammatory response
In simple terms: When tissue is injured, the body immediately sends signals to start inflammation.
Upon wounding, damaged cells release danger signals such as ATP, HMGB1, and DNA, which activate pattern recognition receptors on resident immune cells. This triggers the production of pro-inflammatory cytokines including IL-1alpha, TNF-alpha, and IL-6 [4, 8]. These cytokines act on endothelial cells to increase vascular permeability and expression of adhesion molecules, facilitating immune cell recruitment. The initiation phase is tightly regulated to prevent excessive tissue damage.
Amplification and immune cell recruitment
In simple terms: Inflammation ramps up as more immune cells are called to the wound site.
Cytokines such as IL-6 and IL-17 amplify the inflammatory response by promoting neutrophil and monocyte recruitment [3, 4]. IL-17 family cytokines, produced by Th17 cells and innate lymphoid cells, induce expression of chemokines and antimicrobial peptides. Macrophages arriving at the wound site can further release pro-inflammatory mediators, creating a positive feedback loop that is essential for pathogen clearance but must be controlled to avoid collateral damage [2, 8].
Resolution and macrophage polarization
In simple terms: Inflammation must be turned off, and macrophages switch to a repair mode.
Resolution of inflammation involves active processes that suppress pro-inflammatory signaling and promote tissue repair. Macrophages transition from a pro-inflammatory (M1-like) to a pro-repair (M2-like) phenotype, driven by cytokines such as IL-4, IL-10, and TGF-beta. This switch is critical for angiogenesis, collagen deposition, and wound closure. Dysregulation of this transition leads to chronic wounds or fibrosis [2, 8].
Systemic regulation and multi-omic dynamics
In simple terms: The whole body coordinates inflammation after injury through complex molecular networks.
Recent multi-omic studies have revealed that endurance exercise induces temporal changes in inflammatory mediators across multiple tissues, highlighting systemic regulation. Similarly, perivascular adipose tissue inflammation is regulated by beiging processes that influence vascular remodeling. These findings underscore that regulation of wound inflammation is not confined to the local site but involves systemic signals that can be harnessed therapeutically [1, 5].

How Is regulation of inflammatory response to wounding Regulated?
The inflammatory response to wounding is regulated at multiple levels, including cytokine signaling, transcriptional control, and epigenetic modifications. IL-6-type cytokines signal through JAK-STAT pathways, which are negatively regulated by SOCS proteins. IL-17 family cytokines activate NF-kB and MAPK pathways, which are modulated by ubiquitination and deubiquitination. Macrophage polarization is controlled by transcription factors such as IRF4, IRF5, and STAT6. Additionally, systemic factors such as exercise-induced myokines can modulate inflammation. Perivascular adipose tissue beiging also regulates inflammation in vascular remodeling.
regulation of inflammatory response to wounding and Human Disease
| Gene | Disease / Biology | Potential Experimental Model |
|---|---|---|
| IL6 | Chronic wounds, cytokine storm | IL6 knockout mice; human macrophage knock-in |
| IL17A | Psoriasis, inflammatory skin disease | IL17A knockout mice; skin-specific overexpression |
| CCL2 | Diabetic wound healing impairment | CCL2 knockout mice; macrophage-specific overexpression |
| TGFB1 | Fibrosis, impaired wound healing | TGFB1 conditional knockout; reporter knock-in |
| HIF1A | Chronic wounds, ischemia | HIF1A knockout mice; hypoxia-mimetic treatment |
Chronic wounds and diabetic ulcers
Dysregulation of the inflammatory response to wounding is a hallmark of chronic wounds, including diabetic ulcers. Persistent pro-inflammatory macrophage activation and impaired transition to M2 phenotype lead to tissue destruction and failure to heal. Targeting macrophage polarization is a promising therapeutic strategy.
Inflammatory skin diseases
Conditions such as psoriasis and atopic dermatitis involve excessive IL-17 and IL-6 signaling, which amplify skin inflammation [3, 4]. Understanding the regulation of wound inflammation provides insights into these diseases, as many mediators overlap [3, 8].
Fibrosis and tendinopathy
Unresolved inflammation after tendon injury can lead to insertional Achilles tendinopathy, characterized by degenerative changes and pain. Similarly, excessive TGF-beta signaling during wound healing promotes fibrosis in various tissues.
Systemic inflammatory response and sepsis
Severe wounds can trigger systemic inflammatory response syndrome, which shares molecular pathways with sepsis. Mouse models poorly mimic human inflammatory diseases, highlighting the need for human-relevant models to study regulation.

How CRISPR Can Be Used to Study GO:0106014 regulation of inflammatory response to wounding
Knockout
CRISPR knockout of candidate genes in human macrophages or keratinocytes can determine their necessity for inflammatory responses. For example, IL6 knockout reduces STAT3 activation and downstream inflammatory gene expression. Knockout of CCL2 impairs macrophage recruitment in wound models.
Point Mutation
Introducing precise point mutations in cytokine receptors or signaling molecules can dissect specific phosphorylation sites. For instance, mutating STAT3 tyrosine 705 prevents its activation by IL-6, blocking inflammatory signaling. Such models are valuable for understanding disease-associated variants.
Knock-in
Knock-in of reporter genes (e.g., GFP) or epitope tags allows tracking of inflammatory mediators in real time. Tagging endogenous IL-17A enables visualization of its secretion during wound healing. Knock-in of human IL6 into mice humanizes the inflammatory response for drug testing.
Overexpression
Overexpression of anti-inflammatory genes such as IL10 or SOCS3 can suppress wound inflammation and promote healing [2, 4]. Conversely, overexpressing pro-inflammatory mediators like IL-17A can exacerbate inflammation, modeling chronic wounds.
