Biological Properties and the Role of IL-25 in Disease Pathogenesis

Figure 4

The role of IL-25 in skin diseases. IL-25 can aggravate CU by enhancing the Th2-type immune responses. IL-25 stimulates the proliferation of keratinocytes via activation of the STAT3 transcription factor, inhibits the production of IL-12 to reduce Th1 immune responses, increases the production of IL-13, and decreases the production of IL-23 to inhibit the Th17 immune responses. Thus, IL-25 can improve psoriasis.
