Targeting Signalling Pathways in Chronic Wound Healing

Area of Science:

• Biomedical Sciences
• Wound Healing Research
• Molecular Biology

Background:

• Chronic wounds represent a significant healthcare burden due to delayed healing and limited therapeutic options.
• These non-healing wounds are characterized by dysregulated cellular signaling pathways.
• Current research explores various therapeutic modalities, including natural compounds, stem cells, and drug delivery systems.

Purpose of the Study:

• To review current research on targeting specific signaling pathways implicated in chronic wound pathophysiology.
• To discuss the potential of modulating pathways such as PI3K/AKT, Wnt/β-catenin, TGF-β, Nrf2, Notch, and HIF-1 for therapeutic benefit.
• To highlight novel treatment targets and future research directions for chronic wound management.

Main Methods:

• Comprehensive literature review of studies investigating signaling pathways in chronic wound healing.
• Analysis of research focusing on therapeutic interventions targeting these pathways.
• Synthesis of findings related to naturally derived compounds, stem-cell-based therapy, small molecules, nanoparticles, exosomes, and peptide platforms.

Main Results:

• Dysregulated signaling pathways critically influence the inflammatory, proliferative, and remodeling phases of chronic wounds.
• Modulators of PI3K/AKT, Wnt/β-catenin, TGF-β, Nrf2, Notch, and HIF-1 pathways show promise as therapeutic targets.
• Emerging therapeutic platforms demonstrate potential for effective chronic wound treatment by targeting these pathways.

Conclusions:

• Targeting specific signaling pathways offers a promising strategy for advancing chronic wound treatment.
• Further research into these pathways and novel therapeutic platforms is crucial for improving patient outcomes.
• This review provides insights into the current landscape and future directions for chronic wound therapy.
