Level 5 - mechanism / opinion, no new human data
Narrative review of preclinical mechanisms and formulations
PubMed 41209547 · doi:10.7150/ijms.118118
What was done
This narrative review synthesized literature published between 2016 and 2025 examining the biological mechanisms, physicochemical properties, delivery formulations, and regenerative applications of tripeptides (such as GHK formulations, KdPT, KPV, lipotripeptides, and GPE) in acute and chronic wound healing.
What was found
The abstract reports no quantitative metrics or effect sizes. Qualitatively, it highlights that tripeptides stimulate fibroblast migration, enhance collagen and elastin synthesis, facilitate extracellular matrix remodeling, and support angiogenesis. Specific molecules show distinct properties: GHK derivatives enhance closure and antimicrobial activity; KdPT counteracts hyperglycemia-induced oxidative stress in keratinocytes; KPV hydrogels reduce inflammation and target MRSA; lipotripeptides disrupt bacterial biofilms; and GPE mediates neuroprotection through ERK and PI3K/Akt pathways.
Why it matters
Tripeptides represent versatile bioactive candidates that, when integrated into hydrogels or nanoparticle scaffolds, can address multiple pathological barriers in impaired tissue repair.
Limits
The review provides no systematic search methodology, study quality grading, or meta-analytic data. Quantitative human clinical outcome data are not reported in the abstract, and much of the underlying evidence reflects in vitro and animal model systems with unaddressed issues regarding peptide stability and bioavailability.
