Summary
Chronic wounds fail to heal because microbial communities disrupt the proliferative phase. This new framework, infection-driven proliferative phase impairment (IDPPI), guides targeted therapies to restore healing.
Area of Science:
- Regenerative Medicine
- Microbiology
- Wound Healing Biology
Background:
- Chronic wounds exhibit persistent tissue repair failure beyond infection and inflammation.
- Microbial communities in chronic wounds create pathogenic ecosystems that impair healing.
- The proliferative phase is critical for wound repair, involving cell growth, blood vessel formation, and tissue reconstruction.
Purpose of the Study:
- Introduce the conceptual framework of infection-driven proliferative phase impairment (IDPPI).
- Explain how microbial activities disrupt the host's regenerative programs during wound healing.
- Propose a novel therapeutic paradigm for chronic wound management.
Main Methods:
- Synthesize current evidence on microbial virulence, biofilm formation, and host immune-metabolic dysregulation.
- Analyze mechanisms of proliferative arrest, including cellular injury and signaling pathway disruption.
- Outline a multi-level therapeutic strategy focusing on microbial disarmament and regenerative promotion.
Main Results:
- IDPPI describes a pathological state where microbial actions continuously compromise host repair.
- Coordinated microbial virulence, biofilms, and immune-metabolic issues lead to stalled wound regeneration.
- A targeted therapeutic approach involves suppressing virulence/biofilms, restoring homeostasis, and promoting regeneration.
Conclusions:
- IDPPI provides an integrative framework for understanding chronic wound failure.
- Therapeutic strategies should focus on functional microbial disarmament and enhancing host repair capacity.
- Future advancements in multi-omics, AI, and sensing will enable adaptive, closed-loop regenerative medicine for chronic wounds.

Phases of Wound Repair
Following injury, the integrity of the injured tissues must be reestablished. For example, in skin tissue, wound repair involves coordination among resident skin cells, blood mononuclear cells, extracellular matrix, growth factors, and cytokines to complete the healing cascade.
Formation of Blood Clot
In case of deep injuries, trauma to blood vessels results in blood loss. In the meantime, phospholipids released from the ruptured endothelial cellular membrane are converted into arachidonic...

Overview of Regeneration and Repair
Regeneration and repair processes are critical in healing damages caused by injury, disease, and aging. In regeneration, the damaged tissue is entirely replaced with new growth that restores the original architecture and function. In contrast, tissue repair usually results in a fixed tissue architecture involving scar formation. Scars generally do not reestablish tissue function and may also exhibit structural abnormalities at the injury site.

Healing II: Complications
Complications during healing arise when tissue repair is altered by local or systemic factors. These changes involve abnormal collagen deposition, altered biomechanics, and reduced vascular supply, impairing restoration of normal structure and function.Loss of FunctionScar tissue differs significantly from the original tissue it replaces. In the skin, fibrosis lacks adnexal structures such as hair follicles, sebaceous glands, and sweat glands. Their absence reduces tactile sensitivity, impairs...
Diabetic Foot Ulcer
Definition A diabetic foot ulcer (DFU) is a chronic, non-healing wound that develops in individuals with diabetes. It typically occurs on pressure-bearing areas such as the heel, metatarsal heads, or hallux, and carries a high risk of infection and amputation.Pathophysiology • The development of DFUs can be explained by four interconnected mechanisms: neuropathy, ischemia, infection, and impaired wound healing. • Neuropathy is the most common factor. Sensory neuropathy reduces pain perception,...
Chronic Inflammation: Introduction
Chronic inflammation is a prolonged, dysregulated immune response that persists for weeks to years when the inciting stimulus is difficult to eradicate or when self‑antigens drive ongoing reactivity. Morphologically, it is defined by mononuclear cell infiltration, progressive tissue destruction, and concurrent attempts at healing via angiogenesis and fibrosis. Compared with acute inflammation, edema is less prominent while cellular infiltration predominates; triggers include persistent...
Healing I: Introduction
Healing is the physiological process by which the body restores the integrity and function of damaged tissues following injury. It involves a coordinated interplay of cellular proliferation, extracellular matrix remodeling, and growth factor signaling. The extent and nature of the tissue damage determine whether healing occurs by resolution, regeneration, or replacement.ResolutionResolution represents the most complete form of healing, occurring when the injury is minimal and tissue...
