Type 2 inflammatory response is an inflammatory process driven by the combined action of Th2, type 2 innate lymphoid cell, and type Th2 cytokines. Type Th2 cytokines include interleukin (IL)⁃4, IL⁃5, IL⁃9, IL⁃13, and IL⁃31, primarily secreted by immune cells, as well as IL⁃25, IL⁃33, and thymic stromal lymphopoietin, mainly produced by tissue cells, particularly epithelial cells. With ongoing research into the pathogenesis of type 2 inflammatory response, it has been implicated that abnormal type 2 inflammatory response participated in various skin diseases characterized by chronic tissue inflammation. In recent years, treatment strategies of inhibiting type 2 inflammatory response have continued to evolve, including biologics of target cytokines or their receptors, as well as Janus kinase inhibitors of blocking intracellular cytokine signaling pathways. This paper summarizes progress on the pathogenesis and treatment strategies of type 2 inflammatory skin diseases.
