The etiology and pathogenesis of AD are complex, and may be associated with the interaction between environment, genes and immune system, among which, immunological factor appears to be the most important. As a newly identified CD4+ T cell subset, T helper type 17 ��Th17�� cells are different from Th1 and Th2 cells, and have been demonstrated to play an important role in the initiation and progression of AD. It is considered that Th17 cells can induce inflammatory reaction and immunological reaction by secreting multiple cytokines such as interleukin ��IL)-17, IL-21, IL-22, and so on. Further more, targeted inhibition of Th17 cells and related cytokines by using physical therapy and medication has shown favorable efficacy in the treatment of AD.
