Antibody JRAI is a human monoclonal IgM antibody derived from a patient with juvenile rheumatoid arthritis that is cytotoxic to a subpopulation of normal T lymphocytes. JRAI recognizes approximately 80% of normal peripheral blood T cells, 90% of CD4+ cells, and 75% of CD8+ cells, as determined by complement-mediated cytotoxicity. Within the CD8+ population, JRAI preferentially spares OKM1+ and Leu-11+ cells. These CD8+ cells retain suppressor-effector potential and show enriched natural killer cell activity. Within the CD4+ population, JRAI preferentially kills cells within the Leu-8+ subset, which contains suppressor-inducer cells, and spares the Leu-8- subset, which contains the helpers for immunoglobulin synthesis. JRAI appears to recognize a previously undefined human lymphocyte surface molecule expressed differentially on phenotypically and functionally distinct subsets of human T cells.

D000911	Antibodies, Monoclonal	Antibodies produced by a single clone of cells.	Monoclonal Antibodies,Monoclonal Antibody,Antibody, Monoclonal
D000918	Antibody Specificity	The property of antibodies which enables them to react with some ANTIGENIC DETERMINANTS and not with others. Specificity is dependent on chemical composition, physical forces, and molecular structure at the binding site.	Antibody Specificities,Specificities, Antibody,Specificity, Antibody
D000945	Antigens, Differentiation, T-Lymphocyte	Antigens expressed on the cell membrane of T-lymphocytes during differentiation, activation, and normal and neoplastic transformation. Their phenotypic characterization is important in differential diagnosis and studies of thymic ontogeny and T-cell function.

D001171	Arthritis, Juvenile	Arthritis in children, with onset before 16 years of age. The terms juvenile rheumatoid arthritis (JRA) and juvenile idiopathic arthritis (JIA) refer to classification systems for chronic arthritis in children. Only one subtype of juvenile arthritis (polyarticular-onset, rheumatoid factor-positive) clinically resembles adult rheumatoid arthritis and is considered its childhood equivalent.

D001323	Autoantibodies	Antibodies that react with self-antigens (AUTOANTIGENS) of the organism that produced them.	Autoantibody
D013601	T-Lymphocytes	Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.
