Infectious Agents
Viral and bacterial infections are known to cause a number of different malignancies in populations world-wide. DCEG carries out multidisciplinary studies of carefully selected populations in the United States and abroad, with the goal of clarifying the relationship of infectious agents, especially viruses, to human cancer and other conditions. Recent research has concentrated on human retroviruses (HIV-1), with additional studies on human papillomaviruses (HPV), hepatitis viruses, and papillomaviruses.
Hepatitis Viruses
- Laboratory of Ludmilla Prokunina-Olsson
Dr. Prokunina-Olsson's lab discovered a novel human interferon, IFN-λ4, by performing a follow-up of GWAS findings for clearance of hepatitis C virus (HCV) infection. The IFNL4 genotype plays a key role in hepatitis C virus (HCV) infection, as well as in other conditions. - Hepatitis Viruses and Liver Cancer
DCEG investigators conduct interdisciplinary collaborative studies that integrate epidemiology, virology, and human genetics to study chronic hepatitis virus infection, the cause of most hepatocellular carcinoma (HCC), the third leading cause of cancer mortality worldwide.
Human Papillomavirus (HPV)
