Abstract: Tumor Necrosis Factor-? (TNF?) promotes an inflammatory response resulting in many clinical problems associated with autoimmune disorders such as rheumatoid arthritis, ankylosing spondylitis, inflammatory bowel disease, psoriasis, hidradenitis suppurativa, and refractory asthma. Dysregulation of TNF production is implicated in a variety of human diseases including Alzheimer's disease, cancer, major depression, and inflammatory bowel disease. These disorders are treated with a TNF? inhibitor.

Abstract: Methods and pharmaceutical compositions for preventing and/or treating acute and chronic inflammation and autoimmune diseases are provided herein. Tumor necrosis factor-? (TNF?) promotes an inflammatory response, which causes clinical problems associated with inflammation and autoimmune disorders such as rheumatoid arthritis, ankylosing spondylitis, inflammatory bowel disease, psoriasis, hidradenitis suppurativa, and refractory asthma. TNF? is also implicated in promoting pathogenesis of diabetic retinopathy leading to loss of retinal microvascular cells. Methods herein contain the step of administering a prophylactic and/or therapeutic formulation of a pharmaceutical composition containing a recombinant soluble human TNF receptor or portions thereof which are TNF? inhibitors.

Abstract: Disclosed are novel proteins, referred to as tumor necrosis factor binding proteins, that modulate the activity of tumor necrosis factor. Also disclosed are processes for obtaining the tumor necrosis binding proteins by recombinant genetic engineering techniques.
