We also found that tumor necrosis factor-alpha ( TNF-alpha ) is capable of inducing the surface expression of the CD69 molecule as well as the promoter activity of fusion plasmids that contain 5'-flanking sequences of the CD69 gene, suggesting that this cytokine may regulate in vivo the expression of CD69 .
