Abstract:An in situ hybridization method using radiolabeled oligonucleotide probes was developed to study primary sites of hepatitis A virus replication in an experimental animal model of infection. Hepatitis A genomic sequences were demonstrated in hepatocytes of four marmosets with acute hepatitis A by use of antisense probes. In two of these animals, staining was also found when a sense probe was used, which is consistent with active replication in the hepatocytes. The specificity of the hybridization signal was con… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
