概述

Human Interleukin-13(IL-13)is expressed by the IL13 gene located on the chromosome 5.IL-13 is a 132 amino acid protein containing a proposed 20 amino acid signal peptide,and shares approximately 30%amino acid sequence homology to human IL-4.Additionally,the two cytokines exhibit overlapping biological activities.Human IL-13 is produced by activated Th0,Th1-like Th2-like and CD8 T cells.Similarly to IL-4,IL-13 has multiple effects on the differentiation and functions of monocytes/macrophages.IL-13 can suppress the cytotoxic functions of monocytes/macrophages.IL-13 variant is a natural variant of IL-13 and has a Q instead of R112 of wild type,which associated with increased risk for asthma development and at homozygosity associated with higher levels of serum total IgE in some allergic rhinitis patients.
