Outline of Final Research Achievements |
We investigated antiviral role of immune effecter molecules APOBEC in viral infection of papillomavirus (HPV) and hepatitis B virus (HBV). Experimental results suggest that APOBECs reduce infectivity of HPV16 pseudovirion by interfering viral assemble in vitro. DNA sequencing of clinical samples derived from precancerous cervixs revealed that APOBECs introduce hypermutation in HPV16 viral DNA. Mapping of mutation identifies viral promoter and replication origin as a hot spot of hypermutation mechanism. We also found that AID is induced in hepatocytes by TGFb stimulation and AID forms an RNP complex of viral P protein and host RNA exosome, resulting in degradation of HBV RNA. These studies demonstrate significant role of APOBEC protein in HPV and HBV infection.
