ABSTRACT
Objective To explore the biological functions of retinoic acid-inducible gene-I(RIG-I) in vivo through phenotype analysis of RIG-I knockout mice. Methods The gene expression of RIG-Ⅰ in various tissues of mice was examined with Northern blotting and semi-quantitative RT-PCR.The phenotypes observed included body weight measurement,differential count of peripheral blood cells,metabolic parameters measurement and histopathologic examination. ResultsRIG-Ⅰ expressed in various tissues of mice with different levels.No gross developmental abnormalities and expected maturation arrest in granulocytic differentiation were observed in RIG-Ⅰ knockout mice.However,RIG-Ⅰ knockout mice exhibited an unexpected increase in the ratios of neutrophiles to lymphocytes in peripheral blood and increased susceptibility to bacteria infection. Conclusion RIG-Ⅰ may play an important role in immune regulation in mice.
