Asthma is a chronic lung disease that causes inflammation, thickening and narrowing of airways, as well as an overproduction of mucus. More than 300 million people worldwide suffer from asthma. Asthma symptoms include wheezing, shortness of breath, coughing and tightness of the chest. Interleukin 13 (IL-13) is the key effector cytokine in asthma. IL-13 stimulates airway fibrosis via action of matrix metalloproteinases (MMPs) on tumor transforming growth factor beta (TGN-beta), and also promotes epithelial damage, mucus production and an increased concentration of eosinophils. The inflammatory response characteristic of asthma is augmented by the production of IL-13 and other TH2 cytokines.   All Asthma Antibodies, Lysates, Proteins, and RNAi
