cholangiocyte expression of alpha2beta1-integrin confers susceptibility to rotavirus-induced experimental biliary atresia.inoculation of balb/c mice with rhesus rotavirus (rrv) in the newborn period results in biliary epithelial cell (cholangiocyte) infection and the murine model of biliary atresia. rotavirus infection of a cell requires attachment, which is governed in part by cell-surface expression of integrins such as alpha2beta1. we hypothesized that cholangiocytes were susceptible to rrv infection because they express alpha2beta1. rrv attachment and replication was measured in cell lines derived from cholangi ...200818436621
generation of recombinant rotavirus with an antigenic mosaic of cross-reactive neutralization epitopes on vp4.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]). serological analyses with a panel of anti-vp4- and -vp7-neutralizing monoclonal antibodies revealed that ...200818434390
investigation of the environment and of mothers in transmission of rotavirus infections in the neonatal nursery.a distinct feature of neonatal rotavirus infection is the association of unusual strains that appear to be prevalent only in neonatal units and persist for long periods of time. the main aims of this study were to determine if rotavirus can be detected on environmental surfaces in the neonatal nursery and whether the infection occurs in mothers of infected and uninfected neonates. thirty rotavirus positive neonates and an equal number of negative neonates were enrolled in this study. stool sampl ...200818428133
non-structural protein nsp2 induces heterotypic antibody responses during primary rotavirus infection and reinfection in children.rotaviruses are the single most important causes of severe acute diarrhoea in children worldwide. despite success in developing vaccines, there is still a lack of knowledge about many components of the immune response, particularly those to non-structural proteins. this study established radioimmunoprecipitation (rip) assays using labeled g1p[8], g2p[4], and g4p[6] human rotaviruses to examine the spectrum and duration of rotavirus antibodies in sera collected sequentially for 18-36 months from ...200818428132
