Immunoinformatic Analysis Reveals Antigenic Heterogeneity of Epstein-Barr Virus Is Immune-Driven

open access: yesFrontiers in Immunology, 2021
Whole genome sequencing of Epstein-Barr virus (EBV) isolates from around the world has uncovered pervasive strain heterogeneity, but the forces driving strain diversification and the impact on immune recognition remained largely unknown.

Participation of Multifunctional RNA in Replication, Recombination and Regulation of Endogenous Plant Pararetroviruses (EPRVs)

open access: yesFrontiers in Plant Science, 2021
Pararetroviruses, taxon Caulimoviridae, are typical of retroelements with reverse transcriptase and share a common origin with retroviruses and LTR retrotransposons, presumably dating back 1.6 billion years and illustrating the transition from an RNA to ...

The evolution of virus–induced apoptosis

open access: yesProceedings of the Royal Society of London. Series B: Biological Sciences, 1997
Viruses from several different families are able to exploit their host's cell death programmes so as to maximize viral fitness. Consideration of the evolution of such strategies has lead to the suggestion that the virus should inhibit apoptosis, in order to prolong the life of the cell and thereby maximize the number of progeny virions.

Structural Constraints on RNA Virus Evolution [PDF]

open access: yesJournal of Virology, 1999
ABSTRACT The recently discovered hepatitis G virus (HGV) or GB virus C (GBV-C) is widely distributed in human populations, and homologues such as HGV/GBV-C CPZ and GBV-A are found in a variety of different primate species.

Porcine Reproductive and Respiratory Syndrome Virus: Origin Hypothesis

open access: yesEmerging Infectious Diseases, 2003
Porcine reproductive and respiratory syndrome is a serious swine disease that appeared suddenly in the midwestern United States and central Europe approximately 14 years ago; the disease has now spread worldwide. In North America and Europe, the syndrome

Evolution and Epidemiology of Chikungunya Virus

open access: yes, 2016
Chikungunya is a mosquito-borne Alphavirus that is spreading worldwide in the tropical areas and that has a 11.8 kb RNA genome. The most relevant vectors belong to the genus Aedes and contribute to the diffusion of the three different genotypes of the virus from the original site of first identification in East Africa.

The mode and tempo of hepatitis C virus evolution within and among hosts

open access: yesBMC Evolutionary Biology, 2011
Background Hepatitis C virus (HCV) is a rapidly-evolving RNA virus that establishes chronic infections in humans. Despite the virus' public health importance and a wealth of sequence data, basic aspects of HCV molecular evolution remain poorly understood.
