白细胞介素-13是由小鼠和人类中活化的Th2细胞产生的多效性细胞因子。IL-13主要分泌为132个氨基酸的未糖基化蛋白，分子量为10,000道尔顿。对小鼠IL-13基因的4.3 kb DNA片段进行测序，并以映射11号染色体的单拷贝形式出现。在人类中，IL-13基因的4.6 kb DNA片段以单拷贝形式出现，并映射到5号染色体。IL-13诱导B细胞增殖，还诱导IgE转换。使用人红白血病细胞系TF-1在培养物中检测人和小鼠IL-13产品的增殖活性。

Asthma exacerbations represent a significant disease burden and are commonly caused by rhinovirus (RV), which is sensed by Toll-like receptors (TLR) such as TLR7. Some asthmatics have impaired interferon (IFN) responses to RV, but the underlying mechanisms of this clinically

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

Restoration of the antigen (Ag)-specific immune tolerance in an allergic environment is refractory. B cells are involved in immune regulation. Whether B cells facilitate the generation of Ag-specific immune tolerance in an allergic environment requires further investigation. This paper aims
