Non-enveloped viruses must deliver their viral genome across a cell membrane without the advantage of membrane fusion. The mechanisms used to achieve this remain poorly understood. Human rhinovirus, a frequent cause of the common cold, is a non-enveloped virus of the picornavirus family, which includes other significant pathogens such as poliovirus and foot-and-mouth disease virus. During picor...
Super-short rotavirus strains that have a rearranged gene segment 11 are rarely found in humans, and only five isolates, all from Southeast Asia, have been described in the literature. We report the first isolation in Japan from an infant with severe diarrhea of a rotavirus possessing a super-short RNA pattern. This strain, designated AU19, had a G1 VP7 and is also the first isolate in Japan th...
Development of a vaccine for the common cold has been thwarted by the fact that there are more than 100 serotypes of human rhinovirus (HRV). We previously demonstrated that the HRV14 capsid is dynamic and transiently displays the buried N termini of viral protein 1 (VP1) and VP4. Here, further evidence for this "breathing" phenomenon is presented, using antibodies to several peptides representi...
The majority of human group A rotaviruses possess the P[8] VP4 genotype. Recently, a genetically distinct subtype of the P[8] genotype, also known as OP354-like P[8] or lineage P[8]-4, emerged in several countries. However, it is unclear for how long the OP354-like P[8] gene has been circulating in humans and how it has spread. In a global collaborative effort 98 (near-)complete OP354-like P[8]...
Recombinant rotavirus (RV) with cDNA-derived chimeric VP4 was generated using recently developed reverse genetics for RV. The rescued virus, KU//rVP4(SA11)-II(DS-1), contains SA11 (simian RV strain, G3P[2])-based VP4, in which a cross-reactive neutralization epitope (amino acids 381 to 401) on VP5* is replaced by the corresponding sequence of a different P-type DS-1 (human RV strain, G2P[4]). S...
DNA amplification-restricted transcription-translation (DARTT), is based on DNA amplification by the polymerase chain reaction (PCR) and uses PCR to truncate protein-encoding DNA while adding transcriptional and translational initiation signals to the segment. The amplified DNA segments are transcribed into RNA and translated into protein in vitro and the synthesized proteins are used to define...
T-cell epitopes within viral polypeptide VP4 of the capsid protein of foot-and-mouth disease virus were analyzed using 15-mer peptides and peripheral blood mononuclear cells (PBMC) from vaccinated outbred pigs. An immunodominant region between VP4 residues 16 and 35 was identified, with peptide residues 20 to 34 (VP4-0) and 21 to 35 (VP4-5) particularly immunostimulatory for PBMC from all of th...
Biliary atresia (BA), a neonatal obstructive cholangiopathy, remains the most common indication for pediatric liver transplantation in the United States. In the murine model of BA, Rhesus rotavirus (RRV) VP4 surface protein determines biliary duct tropism. In this study, we investigated how VP4 governs induction of murine BA. Newborn mice were injected with 16 strains of rotavirus and observed ...
During a limited epidemiological study, the serotype specificities of several isolates of bovine rotavirus, exhibiting identical electropherotypes, from a single cattle farm near Bangalore, India, could not be determined using a panel of serotyping monoclonal antibodies (MAbs) specific for G serotypes 1-6 and 10. To determine the genotypes of these isolates, the nucleotide sequences of the gene...
The core of bluetongue virus (BTV) is a multienzyme complex composed of two major proteins (VP7 and VP3) and three minor proteins (VP1, VP4, and VP6) in addition to the viral genome. The core is transcriptionally active and produces capped mRNA from which all BTV proteins are translated, but the relative role of each core component in the overall reaction process remains unclear. Previously we ...
