Gene expression of CD19⁺CD24⁻CD38^hi plasmablasts/plasma cells, regulatory B cells (Bregs), memory B cells, and naïve B cells in patients with immunoglobulin G4-related disease (IgG4-RD). B-cell subsets were sorted from the peripheral blood of patients with IgG4-RD, and total RNA was extracted for microarray analysis. The differences among CD19⁺CD24⁻CD38^hi plasmablasts/plasma cells and other B-cell subsets are shown. Columns from left to right represent CD19⁺CD24⁻CD38^hi plasmablasts/plasma cells, CD19⁺CD24^intCD38^int naïve B cells, CD19⁺CD24⁺CD38⁻ memory B cells, and CD19⁺CD24^hiCD38^hi Bregs, respectively. Red represents overexpressed genes, and blue represents underexpressed genes
