Abstract: The present invention relates to antibodies, antibody fragments, and related molecules that specifically bind to DR3 receptors. Such antibodies have uses, for example, in the prevention, detection, diagnosis, treatment or amelioration of a disease or disorder, especially inflammatory and autoimmune diseases and other immune system disorders, such as Crohn's disease, colitis, Inflammatory Bowel Disease, arthritis, asthma, Multiple Sclerosis, atherosclerosis, and allergic disorders. The invention also relates to nucleic acid molecules encoding anti-DR3 receptor antibodies, vectors and host cells containing these nucleic acids, and methods for producing the same.

Abstract: The invention relates to methods of preventing, treating, and ameliorating asthma, allergen-induced respiratory symptoms, and/or an allergic or inflammatory condition of the lung or respiratory system in a patient by administering B Lymphocyte Stimulator antagonists. In addition, the invention provides a method of reducing total serum IgE levels in a patient suffering from asthma, and/or an allergic or inflammatory condition of the lung or respiratory system by administering B Lymphocyte Stimulator antagonists. The invention further provides a method of treating, preventing or ameliorating an allergen-induced airway hyper responsiveness or increase in mucus-containing cells and/or mucus accumulation or production in the airway epithelium of a patient by administering B Lymphocyte Stimulator antagonist.
