背景说明： Interleukin-13 is also known as IL-13.It is a protein that in humans is encoded by the IL13 gene.Interleukin-13 is an immunoregulatory cytokine produced primarily by activated Th2 cells.It is involved in several stages of B-cell maturation and differentiation.It up-regulates CD23 and MHC class II expression，and promotes IgE isotype switching of B cells.This cytokine down-regulates macrophage activity，thereby inhibits the production of pro-inflammatory cytokines and chemokines.This cytokine is found to be critical to the pathogenesis of allergen-induced asthma but operates through mechanisms independent of IgE and eosinophils.
