Urinary bladder epithelial cells play an important role in the host defense against urinary tract infections. Interferon-gamma (IFN-gamma) is a potent cytokine that regulates immune responses by inducing multiple genes in many types of cells including urinary bladder epithelial cells. Retinoic acid-inducible gene-I (RIG-I) is a member of the DExH-box family, which is involved in various reactions related to RNA metabolism, and is induced in leukemic cells by retinoic acid or in endothelial cells by lipopolysaccharide. We have studied the expression of RIG-I in T24 cells, a cell line derived from human urinary bladder epithelial carcinoma cells. IFN-gamma stimulated T24 cells to express RIG-I mRNA and protein in concentration- and time-dependent manners. Immunohistochemical analysis revealed the expression of RIG-I in the urinary bladder epithelium from a patient with chronic urinary tract infection and in a bladder epithelial carcinoma. We conclude that RIG-I may play some role in inflammatory reactions in the urinary tract epithelium.
