Markers of activated T cells on synovial fluid lymphocytes in rheumatoid arthritis. 1979

A Mathieu

Membrane markers of activated T lymphocytes of synovial fluid of two groups of patients with various forms of arthritis were studied. The first group (group A) concerns patients affected by rheumatoid arthritis (RA), and the other (group B) includes those affected by not immunologically-mediated arthropathies as osteoarthrosis, crystal synovitis, post-traumatic arthritis. Some other arthropathies included in a third group (group C) have been considered separately. Both the receptor for human group O Rh negative erythrocytes (H rosettes forming cells) and the receptor able to bind at 37 degrees C sheep red blood cells (stable-E-rosette forming cells) respectively were used as markers for the identification of activated T lymphocytes. The results show a marked increase of activated T cells in group A in comparison to group B. So the possible causes of this lymphocyte activation in rheumatoid patients are suggested.

D008213	Lymphocyte Activation	Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION.

D008297	Male		Males
D011947	Receptors, Antigen, B-Cell	IMMUNOGLOBULINS on the surface of B-LYMPHOCYTES. Their MESSENGER RNA contains an EXON with a membrane spanning sequence, producing immunoglobulins in the form of type I transmembrane proteins as opposed to secreted immunoglobulins (ANTIBODIES) which do not contain the membrane spanning segment.

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.

D001172	Arthritis, Rheumatoid	A chronic systemic disease, primarily of the joints, marked by inflammatory changes in the synovial membranes and articular structures, widespread fibrinoid degeneration of the collagen fibers in mesenchymal tissues, and by atrophy and rarefaction of bony structures. Etiology is unknown, but autoimmune mechanisms have been implicated.	Rheumatoid Arthritis

D012397	Rosette Formation	The in vitro formation of clusters consisting of a cell (usually a lymphocyte) surrounded by antigenic cells or antigen-bearing particles (usually erythrocytes, which may or may not be coated with antibody or antibody and complement). The rosette-forming cell may be an antibody-forming cell, a memory cell, a T-cell, a cell bearing surface cytophilic antibodies, or a monocyte possessing Fc receptors. Rosette formation can be used to identify specific populations of these cells.	Immunocytoadherence,Formation, Rosette,Formations, Rosette,Immunocytoadherences,Rosette Formations
