Yang et al. [7] constructed MGO-induced PF rat and cultured cells in vitro and found that TGF-β1 can stimulate ADSCs to secrete more IL-6 and increase the expression of the macrophage gene Arg-1, thereby promoting the polarization of M2 macrophages to decrease PF in rats. This evidence concerns the gene TGFB1 and pemphigus foliaceus.
