In this study, we tested the protective effect of UV-B treated HG-HaCaT-Exos on Schwann cells (SCs) injured by HG (high glucose) model. At first, we determined the dose of UV-B radiation and the time for the release of HaCaT-Exos. Furthermore, the Schwann cells were injured through the HG model, isolated by ultracentrifugation from the HaCaT cell culture supernatant were co-incubated within the injured cells. It was found that UV-B treated HaCaT-Exos decrease apoptosis and increase the viability of injured SC by transferring miR-222 from HaCaT cells to them via exosomes, hence protecting them.
