  • Research


      The specific goals of our laboratory are to establish an interdisciplinary approach to investigate the fundamental control mechanisms of gene expression process in conjunction with viral infection and stress-related disorders. Current efforts focus on the investigation of the biological roles of cellular and viral gene factors and their impacts on cellular defense mechanism. One of these studies has been extended to the establishment of a gene therapy technique in bone marrow or primary cells. These works will be thus allowing us to provide a ultimate therapy scheme for the treatment of a variety of cellular disorder and deficiency.




    ⦾ Research area
