Abstract: This invention relates to a TRAF family molecule, a polynucleotide encoding the molecules, an antibody against the molecules, and an antisense polynucleotide of the molecule. Employing an oligo-DNA primer capable of amplifying the most highly conserved region of a known TRAF family molecule, PCR was performed with the aid of cDNA derived from various cell strains and tissues as a template. Thus, the base sequence of the gene of an unknown TRAF family molecule and the amino acid sequence of the TRAF family molecule encoded by the gene were elucidated. An antibody against the molecule was also prepared. By utilizing the TRAF family molecules, genes thereof, and antibodies against the molecules, there are provided methods for elucidating the functions of the proteins and methods for elucidating the signal transduction system of the TNF-R family involving the molecules, as well as probes for research and diagosis, which suggest applications in therapeutic agents.

Abstract: The invention provides therapeutic agents for hepatitis, comprising an antibody against a human Fas ligand, or an active fragment thereof as an active ingredient. The therapeutic agents for hepatitis according to the invention are particularly effective for the treatment of hepatitis caused by the death of hepatocytes due to apoptosis among many kinds of hepatitis.

Abstract: A drug for the treatment of rheumatoid arthritis, which comprises as an active ingredient a monoclonal antibody which recognizes specifically extracellular region of human VLA-2. Preferable drug for the treatment of rheumatoid arthritis comprises as an active ingredient a monoclonal antibody which recognizes specifically extracellular region of human VLA-2, .alpha. chain. The above drug for the treatment of rheumatoid arthritis can suppress swelling due to arthritis in rheumatoid arthritis with low toxicity and hence is useful for the treatment of rheumatoid arthritis.

Abstract: A monoclonal antibody specifically reactive to hamster immunoglobulins, a hybridoma producing said monoclonal antibody, and an immunoassay utilizing said monoclonal antibody are provided. The monoclonal antibody is useful in an immunoassay as a secondary antibody to a hamster-derived primary antibody or antiserum raised against various antigens.
