From: B cell-activating factor of the tumor necrosis factor family (BAFF) is expressed under stimulation by interferon in salivary gland epithelial cells in primary Sjögren's syndrome

Figure 4

Immunocytochemical analysis of BAFF expression in salivary epithelilal cells from minor salivary glands. Positive staining for B cell-activating factor (BAFF) 48 hours after stimulation with IFN-α (2,400 U/ml) (c) and with IFN-γ (5 ng/ml) (d) was markedly enhanced compared with baseline (b). (a) Negative control with polyclonal rat immunoglobulin.
