Certain types of human papillomavirus (HPV), notably HPV type 16, are associated with flat or inverted proliferative lesions of the cervix uteri that can progress to malignancy. As a first step towards the serological study of the epidemiology of HPV, we have synthesized the entire amino acid sequences of the 2 major viral capsid proteins of HPV type 16, L1(More)
Shortly after the discovery of human herpesvirus 6 (HHV-6), two distinct variants, HHV-6A and HHV-6B, were identified. In 2012, the International Committee on Taxonomy of Viruses (ICTV) classified HHV-6A and HHV-6B as separate viruses. This review outlines several of the documented epidemiological, biological, and immunological distinctions between HHV-6A(More)
There are few genes that are specific and diagnostic for human herpesvirus-6. U83 and U22 are two of them. U22 is unique, whereas U83 encodes distant similarity with some cellular chemokines. Reverse transcription-polymerase chain reaction, cDNA cloning, and sequence analyses show polyadenylated RNA transcripts corresponding to minor full-length and(More)
The human herpesvirus 6 (HHV-6) variant A genome has conserved sequences which are signals for initiating lytic replication (origin, 'ori-lyt') and DNA packaging into the virion (pac2/1). Here these are functionally characterised and used to construct a gene-expression amplifiable-vector, an 'amplicon', with applications for gene delivery to(More)
After inheritance of chromosomally integrated HHV-6 (ciHHV-6), viral DNA is found in every nucleated cell. The prevalence of ciHHV-6 is estimated to be 0.2-5% of humans. There are conflicting data on the potential for replication, possibly leading to clinical implications. We analysed peripheral blood mononuclear cells (PBMCs) from individuals with ciHHV-6(More)
