一般描述
IL13 (interleukin 13) is a classic cytokine produced by Th2 (T-helper) cells. It was originally identified as an inflammatory cytokine production-inhibiting T-cell derived cytokine. Recombinant rat IL-13 is an 11.9 kDa protein containing 109 amino acid residues.
生化/生理作用
IL13 (interleukin 13) is up-regulated during parasitic infections, and participates in host′s protective immunity against Schistosoma japonicum. This protein promotes eosinophil activation resulting in elevated specific IgE against adult and larval antigens. During acute infection it promotes egg expulsion through increased intestinal contractility. It acts as a liver protective agent where it promotes formation of liver granulomas in a CD4+ T cell-mediated manner, which results in liver fibrosis. In airway disorders, such as asthma, chronic obstructive pulmonary disease (COPD), and cystic fibrosis lung disease, IL13 promotes the formation of airway goblet cells, resulting in excess mucus secretion, which in turn, is regulated by IL13-activated autophagy.

The leukotrienes (LTs) enhance allergen- and interleukin (IL)-13-dependent allergic lung inflammatory disease. However, the precise requirement of LTs and the mechanism by which they elicit allergic lung responses remain uncertain. To clarify the involvement of LTs in respiratory allergen- and

Cytokine modulation of autophagy is increasingly recognized in disease pathogenesis, and current concepts suggest that type 1 cytokines activate autophagy, whereas type 2 cytokines are inhibitory. However, this paradigm derives primarily from studies of immune cells and is poorly characterized
