    Arthritis Rheumatol 2018 Feb 18. Epub 2018 Feb 18.
    University of Oklahoma Health Sciences Center, Oklahoma City, OK.
    Objective: To better understand the role of B cells, potential mechanisms for their aberrant activation, and the production of autoantibodies in the pathogenesis of Sjögren's Syndrome (SS), we explored selection pressures and N-glycosylation acquired by somatic mutation (acN-glyc) in the immunoglobulin (Ig) variable regions (V-regions) of antibody secreting cells (ASCs) isolated from the minor salivary glands of SS patients and non-SS controls with sicca symptoms.

    Methods: We report a novel method to produce and characterize recombinant monoclonal antibodies (mAbs) from SS patient and control labial salivary gland single-cell sorted ASC infiltrates that can be utilized to concurrently probe any other expressed genes. V-regions were amplified by RT-PCR, sequenced, and analyzed for incidence of N-glycosylation and selection pressure, then expressed as the native mAbs, or mutant mAbs lacking the acN-glyc for specificity testing.
