In 55 patients with primary Sjögren's syndrome (PSJS), we studied on peripheral HLA-DR positive T cells, suppressor inducer (CD4 + CD45R) cell and helper inducer (CD4 + CDw29) cells by 2-color analysis using flow cytometry system. As shown in systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), progressive systemic sclerosis and myositis, the rate of pheripheral HLA-DR positive T cells in PSJS (5.9% +/- 3.9) was significantly higher than in normal (1.6% +/- 1.1). The rate of CD4 +/- CD45R + cells in PSJS (12.8% +/- 6.1) and SLE (12.8% +/- 8.2) were significantly lower than in normal (16.6% +/- 3.9). With respect to the disease pattern of PSJS, the increase of HLA-DR positive T cell and decrease of CD4 + CD45R cell were recognized in patients with leucopenia, high titer of anti-RNP antibody and/or abnormal findings of sialography, and the decrease of CD4 + CD45R + cell was not recognized in patients with kerato-conjunctivitis sicca alone. In either SLE or RA, there were no correlations between the rate of T cell subsets (HLA-DR positive T cells and CD4 + CD45R cells) and the degree of salivary gland damage. T cell subsets in PSJS were useful indicators of disease severity and it is also useful for classifying PSJS into several subtypes. To analyze T cell surface markers in PSJS is very important for investigation of functions of lymphocytes in this disease.

UI MeSH Term Description Entries
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D006649 Histocompatibility Antigens A group of antigens that includes both the major and minor histocompatibility antigens. The former are genetically determined by the major histocompatibility complex. They determine tissue type for transplantation and cause allograft rejections. The latter are systems of allelic alloantigens that can cause weak transplant rejection.

D006684 HLA-DR Antigens A subclass of HLA-D antigens that consist of alpha and beta chains. The inheritance of HLA-DR antigens differs from that of the HLA-DQ ANTIGENS and HLA-DP ANTIGENS. HLA-DR,Antigens, HLA-DR,HLA DR Antigens

D000328 Adult A person having attained full growth or maturity. Adults are of 19 through 44 years of age. For a person between 19 and 24 years of age, YOUNG ADULT is available. Adults
D000368 Aged A person 65 years of age or older. For a person older than 79 years, AGED, 80 AND OVER is available. Elderly
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.

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.

D015496 CD4-Positive T-Lymphocytes A critical subpopulation of T-lymphocytes involved in the induction of most immunological functions. The HIV virus has selective tropism for the T4 cell which expresses the CD4 phenotypic marker, a receptor for HIV. In fact, the key element in the profound immunosuppression seen in HIV infection is the depletion of this subset of T-lymphocytes.

D015704 CD4 Antigens 55-kDa antigens found on HELPER-INDUCER T-LYMPHOCYTES and on a variety of other immune cell types. They are members of the immunoglobulin supergene family and are implicated as associative recognition elements in MAJOR HISTOCOMPATIBILITY COMPLEX class II-restricted immune responses. On T-lymphocytes they define the helper/inducer subset. T4 antigens also serve as INTERLEUKIN-15 receptors and bind to the HIV receptors, binding directly to the HIV ENVELOPE PROTEIN GP120.
