The connexin mimetic peptide Gap27 improves cell motility in human skin models despite raised glucose, insulin and IGFBP-5

Research output: Chapter in Book/Report/Conference proceedingConference contribution


In chronic non-healing diabetic wounds Connexin43 (Cx43) is upregulated at the wound edge compared to ‘normal’ skin wounds. Reduced Cx43 expression/function is associated with improved wound closure rates, consistent with our data to date showing that the Cx43 channel blocker, Gap27, increases scrape-wound closure rates in human skin models. Insulin Growth Factor-I (IGF-I) also stimulates skin wound healing whilst its actions can be attenuated by IGF binding protein 5 (IGFBP-5). The IGF-I:IGFBP-5 ratio is altered in diabetic skin and maybe of clinical significance.
