It is important to consider that TGFβ-stimulated myofibroblastic differentiation is effectively inhibited by the inflammatory cytokine TNF as described for dermal [17] and gingival fibroblast [23] In addition, TNF may impair wound healing in diabetes [24], suggesting that this cytokine is probably implicated in delayed wound healing in different contexts. The gene discussed is TGFB1; the disease is diabetes mellitus.
