What was done
The authors reviewed the molecular and cellular mechanisms through which photobiomodulation (PBM) restores mitochondrial homeostasis to enhance diabetic wound healing. The review synthesizes the biological targets of PBM, relevant downstream signaling pathways, and combination strategies with advanced biomaterials, small molecules, and stem cell-derived therapeutics.
What was found
The abstract reports no numerical findings, effect sizes, or study counts. Qualitatively, it reports that PBM targets cytochrome C oxidase to increase oxidative phosphorylation and ATP generation, modulates mitochondrial dynamics by downregulating Drp1 and upregulating Mfn2, promotes macrophage polarization from M1 to M2 phenotypes, and activates pathways associated with angiogenesis, cell proliferation, and inflammation resolution (such as VEGF, PI3K/AKT/mTOR, AMPK, and TGF-β/Smad).
Why it matters
This review maps the mechanistic framework linking light-based therapy to mitochondrial bioenergetics and cellular repair in diabetic tissue. It highlights how combining PBM with modern biomaterials and cell therapies could improve non-healing diabetic wounds.
Limits
The abstract contains no primary human data, quantitative meta-analyses, or specified systematic review methodology. The outlined mechanisms rely primarily on bench and preclinical studies, and clinical translation is currently limited by a lack of standardized treatment parameters and dosing protocols.
