Furthermore, the epithelial-derived cytokines interleukin-33 (IL-33), interleukin-25 (IL-25), and thymic stromal lymphopoietin (TSLP), as well as the innate immune cell-derived cytokine high mobility group box 1 (HMGB1), activate and induce ILC2 function, thereby promoting the progression of type 2-mediated pulmonary diseases (Figure 1) [59,60,61,62,63,64]. The gene discussed is TSLP; the disease is lung disorder.
