Sera of patients with multiple sclerosis (19 out of 65, 29%), progressive systemic sclerosis (4 out of 17, 23%), systemic lupus erythematosus (4 out of 19, 21%), and Sjogren syndrome (2 out of 19, 10%) contained significantly higher HRES-1 peptide binding activity than sera of normal donors.

The expression of HRES-1 salivary gland may explain its antigenicity in a small proportion of Sjögren's syndrome patients as well as suggesting mechanisms whereby it may contribute to the chronic inflammation of autoimmune disease.

Cytokine-mediated up-regulation of VCAM-1 and ICAM-1 that facilitates the recruitment of VLA-4 and LFA-1 expressing T cells might contribute to lymphoid cell infiltration in the salivary and lacrimal glands in SS.

Increased levels of VCAM-1, ICAM-1, IFN-gamma, and IL-1 beta mRNA were demonstrated by RT-PCR, whereas E-selectin mRNA were weakly expressed in SS lacrimal and salivary gland tissues.
Using reverse transcriptase and a quantitative PCR to measure cytokine mRNA, we found Sjögren's syndrome: 1) salivary gland CD4+ T cells produce over 40-fold more IL-2, IFN-gamma, and IL-10 mRNA than peripheral blood CD4+ T cells from the same patient or from normal controls; 2) salivary gland CD4+ T cells produced little IL-4 and IL-5 mRNA immediately after elution from the salivary gland, although these mRNAs could be induced by mitogen stimulation of Sjögren's syndrome salivary gland lymphocytes in vitro; 3) salivary gland epithelial cells produced over 40-fold more IL-1 alpha, IL-6, and TNF-alpha mRNA than epithelial cells from individuals with histologically normal salivary glands.
Comparative influence of steroid hormones and immunosuppressive agents on autoimmune expression in lacrimal glands of a female mouse model of Sjögren's syndrome.

One gene, two transcripts: isolation of an alternative transcript encoding for the autoantigen La/SS-B from a cDNA library of a patient with primary Sjögrens' syndrome.
