TNF binding ligands and antibodies

摘要

Antibodies to tumor necrosis factor receptors (TNF-Rs) are disclosed together with methods of producing them. The antibodies are preferably those which inhibit the cytotoxic effect of TNF but not its binding to the TNF-Rs. Most preferably, the antibodies bind to an extracellular domain of the C-terminal cysteine loop of the p75 TNF receptor, which loop consists of the amino acid sequence Cys-185 to Thr-201 of SEQ ID NO:3.
