Department of Immunology, University Hospital Medical School, Brest, France.

The peripheral blood from 15 patients with primary Sjögren's syndrome and from 15 matched controls was examined for the presence of activated T and B lymphocytes, by using monoclonal antibodies directed to interleukin-2 (IL-2) and transferrin receptors, and to HLA-DR determinants. The number of circulating positive-T cells was significantly greater in the patients than in the controls, irrespective of disease activity. There were more of the CD8 cells than of the CD4 cells that expressed IL-2 receptors. There was a small but significant increase in activated B cells in the patients, since this population is virtually absent from the normal blood.

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.

D000911 Antibodies, Monoclonal Antibodies produced by a single clone of cells. Monoclonal Antibodies,Monoclonal Antibody,Antibody, Monoclonal
D000943 Antigens, Differentiation Antigens expressed primarily on the membranes of living cells during sequential stages of maturation and differentiation. As immunologic markers they have high organ and tissue specificity and are useful as probes in studies of normal cell development as well as neoplastic transformation.

D001402 B-Lymphocytes Lymphoid cells concerned with humoral immunity. They are short-lived cells resembling bursa-derived lymphocytes of birds in their production of immunoglobulin upon appropriate stimulation.

D012859 Sjogren's Syndrome Chronic inflammatory and autoimmune disease in which the salivary and lacrimal glands undergo progressive destruction by lymphocytes and plasma cells resulting in decreased production of saliva and tears. The primary form, often called sicca syndrome, involves both KERATOCONJUNCTIVITIS SICCA and XEROSTOMIA. The secondary form includes, in addition, the presence of a connective tissue disease, usually rheumatoid arthritis.

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.
