The laboratory is focused on antiviral therapies against hepatitis B and C viruses using a variety of cell culture and enzyme-based technologies. Investigations examine a wide range of parameters (DNA, RNA, proteins), both viral and cellular utilizing a variety of molecular biology-based techniques. Studies extend from basic screening (e.g. drug discovery) to mechanisms of action.
Previously, Dr. Korba was part opf the research faculty within the Division of Molecular Virology at the Dept of Microbilogy & Immunology in Rockville, MD. DMVI faculty and research staff have now permanently relocated to the Washington, DC Georgetown University Medical Center Campus.
Over the years, members of the DMVI laboratory have conducted investigations, often involving collaborations with various NIAID scientists, grantees and contractors, in projects involving rhinoviruses, mouse hepatitis virus, influenza viruses (equine and human), parainfluenza 1, 2 & 3 viruses, measles virus, virions of progressive multifocal leukoencephalopathy, agents of nonbacterial gastroenteritis (Norwalk agent and rotaviruses), adenoviruses, vaccinia virus, respiratory syncytial virus, hepatitis A virus, hepatitis B virus, hepatitis C virus, hepatitis D virus, hepatitis E virus, woodchuck hepatitis virus, human immunodeficiency virus, simian immunodeficiency virus, feline immunodeficiency virus, human herpesvirus-6 and human herpesvirus-7.
The research efforts have ranged from basic virology to studies aimed at defining the natural history of infection and disease, diagnostic methodology, prevention by passive and active immunization and treatment. These activities have resulted in many publications in the scientific literature.
