Breaking the Hybrid–Species Barrier
It’s been more than 50 years since John Gurdon first placed a nucleus from a differentiated cell of a Xenopus laevis tadpole into an enucleated Xenopus egg and regenerated a complete animal. This demonstrated two important facts: the somatic cell nucleus contains the complete genetic information needed for the production of the organism, and nuclei of differentiated cells can be reprogrammed in...
متن کاملEighth Major Clade for Hepatitis Delta Virus
Hepatitis delta virus is the only representative of the Deltavirus genus, which consists of 7 differentiated major clades. In this study, an eighth clade was identified from 3 distinct strains. Deltavirus genetic variability should be considered for diagnostic purposes. Clinical consequences of the diversity have yet to be evaluated.
متن کاملHepatitis Delta Virus RNA Replication
Hepatitis delta virus (HDV) is a distant relative of plant viroids in the animal world. Similar to plant viroids, HDV replicates its circular RNA genome using a double rolling-circle mechanism. Nevertheless, the production of hepatitis delta antigen (HDAg), which is indispensible for HDV replication, is a unique feature distinct from plant viroids, which do not encode any protein. Here the HDV ...
متن کاملHepatitis Delta Virus: A Peculiar Virus
The hepatitis delta virus (HDV) is distributed worldwide and related to the most severe form of viral hepatitis. HDV is a satellite RNA virus dependent on hepatitis B surface antigens to assemble its envelope and thus form new virions and propagate infection. HDV has a small 1.7 Kb genome making it the smallest known human virus. This deceivingly simple virus has unique biological features and ...
متن کاملThe middle hepatitis B virus envelope protein is not necessary for infectivity of hepatitis delta virus.
The hepatitis delta virus (HDV) envelope contains the large (L), middle (M), and small (S) surface proteins encoded by coinfecting hepatitis B virus. Although HDV-like particles can be assembled with only the S protein in the envelope, the L protein is essential for infectivity in vitro (C. Sureau, B. Guerra, and R. Lanford, J. Virol. 67:366-372, 1993). Here, we demonstrate that the M protein, ...
