13. Clinical studies of renal disease in Sjögren's syndrome.
When 17 patients with Sjögren's syndrome, without apparent clinical manifestations of renal disease, were examined renal function studies frequently indicated abnormalities in their renal phosphate handling. The percentage tubular reabsorption of phosphate (%TRP) was decreased in six (35.3%), and maximal tubular reabsorption rate for phosphate (TmPO4/GFR) w

14. T cell receptor repertoire of infiltrating T cells in lips of Sjögren's syndrome patients.
Infiltrating T cells around salivary glands in the lips of Sjögren's syndrome (SjS) patients are crucial in the pathogenesis of this disease. To analyze the nature of infiltrating T cells, their T cell receptor repertoire was examined with quantitative polymerase chain reaction. The repertoire of V beta transcripts in lips of SjS was not restricted; however

15. Anti-α-fodrin antibodies do not add much to the diagnosis of Sjögren's syndrome
The presence of anti-α-fodrin autoantibodies has been reported to be a highly specific and sensitive test for the diagnosis of Sjögren's syndrome (SjS). We looked (in Nijmegen) for anti-α-fodrin, anti-Ro60, and anti-La autoantibodies in a cohort of 51 patients with rheumatic diseases (primary SjS [21], secondary SjS [6], rheumatoid arthritis [RA] [12], sy

16. Alpha 1 antitrypsin (PI) phenotypes in two rheumatic diseases: a reappraisal of the association of PI subtypes in rheumatoid arthritis.
alpha 1 Antitrypsin phenotypes were determined by isoelectric focusing in 225 adult white patients with rheumatoid arthritis (RA), 60 patients with severe rheumatoid arthritis (grade III and IV), 17 sibling pairs--HLA identical but discordant for rheumatoid arthritis, and 122 random patients with Sjögren's syndrome. No significant increase in non-M phenotyp

17. Association of BAFF/BLyS overexpression and altered B cell differentiation with Sjögren’s syndrome
BAFF (BLyS, TALL-1, THANK, zTNF4) is a member of the TNF superfamily that specifically regulates B lymphocyte proliferation and survival. Mice transgenic (Tg) for BAFF develop an autoimmune condition similar to systemic lupus erythematosus. We now demonstrate that BAFF Tg mice, as they age, develop a secondary pathology reminiscent of Sjögren’s syndrome (

18. Antibody-dependent cell-mediated cytotoxicity in selected autoimmune diseases.
Antibody-dependent cell-mediated cytotoxicity mediated by peripheral blood lymphocytes was studied in patients with systemic lupus erythematosus, polyarteritis nodosa. Sjogren's syndrome, and rheumatoid arthritis. The target cells were chicken erythrocytes coated with rabbit anti-chicken erythrocyte antibody. Antibody-dependent cell-mediated cytotoxic activi

19. T lymphocyte activation state in the minor salivary glands of patients with Sjögren's syndrome.
Local lymphoplasmacytoid infiltration of the diseased exocrine glands is a cardinal sign of Sjögren's syndrome (SS). The state of T lymphocyte activation present in these local infiltrations was studied by three different techniques: determination of interleukin 2 (IL2) receptor (Tac) on cell surface membrane; autoradiography combined with immunoperoxidase

20. Serum immunoreactive prolyl hydroxylase in inflammatory rheumatic diseases.
Serum immunoreactive prolyl hydroxylase protein (S-IRPH) was measured in 56 patients with inflammatory rheumatic diseases, and the values were compared with those in 32 control subjects. S-IRPH was above the 95% confidence limit of the controls in about 70% of the patients with active systemic lupus erythematosus, rheumatoid arthritis, scleroderma, Reiter's

21. Monocytoid B cell lymphoma.
The clinical, light microscopic, ultrastructural, immunocytochemical and cytogenetic features of a case of monocytoid B cell lymphoma were investigated. The tumour initially affected the cervical and supraclavicular nodes, but 33 months later affected the left parotid salivary gland. The patient had subclinical Sjögren's syndrome. The neoplastic cells showe

22. Functional affinity of IgM rheumatoid factor in patients with rheumatoid arthritis and other autoimmune diseases.
The functional affinity of IgM rheumatoid factors (RF) was measured in 31 patients with rheumatoid arthritis (RA), 24 with systemic lupus erythematosus (SLE), 13 with Sjögren's syndrome (SS), and in 13 seropositive healthy individuals. The functional affinity of IgM RF from patients with RA was significantly lower than in the other clinical groups studied.

23. Cathepsin S inhibitor prevents autoantigen presentation and autoimmunity
The cysteine endoprotease cathepsin S mediates degradation of the MHC class II invariant chain Ii in human and mouse antigen-presenting cells. Studies described here examine the functional significance of cathepsin S inhibition on autoantigen presentation and organ-specific autoimmune diseases in a murine model for Sjögren syndrome. Specific inhibitor of ca

24. Molecular analysis of the 60-kDa human Ro ribonucleoprotein.
Ro, or Sjogren syndrome type A (SS-A), antigen is the most prevalent of the human systemic autoimmune specificities and exists as an inabundant ribonucleoprotein complex (RNP) composed of a 60,649-Da protein, as defined here by cDNA cloning, and the human Y RNAs. The recombinant 60-kDa Ro protein and human Y1 RNA were reconstituted in vitro, and the binding
