Regulation of mesenchymal stem cell-derived exosomes on helper T cells in periodontitis [PDF]
T helper cells (Th cells) play an important role in periodontitis. During the progression of periodontitis, the levels of pro-inflammatory cytokines such as INF-γ and IL-17, which are produced by Th1 and Th17 cells, are elevated, while the levels of anti-
