RDKVYR, known under the trade name Imunofan (IM) , is a modified peptide sequence derived from the human thymopoietin hormone (TH5) corresponding to amino acids 32-37. We recently proved that wounds treated with this peptide showed accelerated migration of keratinocytes and appeared to be richer in fibroblasts. In addition, it is involved in transcriptional induction of the POUF5F1 gene encoding OCT4 pluripotency factor and the TET1 and TET3 genes involved in active DNA demethylation . Both TET genes and POUF5F1 are involved in skin regeneration processes.
