Figure 1From: Abnormalities of B cell phenotype, immunoglobulin gene expression and the emergence of autoimmunity in Sjögren's syndromeAnalysis of the distribution of peripheral CD19+ B cell subsets demonstrates that patients with primary Sjögren's syndrome (pSS) have reduced frequencies of CD27+ memory B cells in the peripheral blood compared with normal donors. In addition, patients with pSS with secondary non-Hodgkin lymphoma exhibited an increase in CD27+ B cells in the blood.Back to article page
