Fluorescence-activated cell sorting analysis of monocytes and lymphocytes. (A) and (B) Normal (gray line) and primary Sjögren's syndrome (pSS) (black line) monocytes were cultured for 96 hours without stimulation, and CD14+/BAFF-R+ cells (A) and CD14+/TACI+ cells (B) were examined by fluorescence-activated cell sorting (FACS) analysis. (C) and (D) Lymphocytes in whole blood samples of a normal individual (gray line) and a pSS patient (black line) were examined by FACS analysis for CD20+/BAFF-R+ cells (B cells in part (C)) and CD4+/BAFF-R+ cells (T cells in part (D)). Light gray lines represent isotype controls. Representative data derived by FACS analysis are shown. BAFF-R = B cell activating factor receptor; TACI = transmembrane activator and calcium modulator and cyclophilin ligand interactor.
