Compared with the healthy control-recipient group, the BD-recipient group showed an increased mRNA expression of IFN-γ, IL-17, monocyte chemotactic protein-1 (MCP-1), IL-1β, and tumor necrosis factor-α (TNF-α); in contrast, IL-10 mRNA expression was decreased in the BD-recipient group compared with the control group. This evidence concerns the gene TNF and Behcet disease.
