ABSTRACT
Respiratory syncytial virus (RSV) is one of the major pathogens of acute respiratory infections, becoming a huge global burden. Virus-receptor interactions play a key role in the pathogenesis of RSV infection. The distribution of receptors influences the cellular and the tissue tropism of RSV as well as the viral replication and proliferation in the host. However, the RSV receptors are currently unknown, which is one of the reasons that hinders the development of RSV vaccines and therapeutic drugs. In this study, the existing RSV receptors are reviewed with the hope to provide ideas for the research of RSV vaccines and therapeutic drugs.
ABSTRACT
Two methods of different RNA extractions from Conus venom tube and toxin gland of seven cone snail species were performed. ThermoScript~ TM RNase H~ - Transcriptase and AMV Transcriptase were used to synthesize cDNA separately. The cDNAs were used as templates to amplify conotoxin genes by PCR.The optimized RNA isolation and cDNA synthesis methods were obtained according to RT-PCR results, which would be the basis for cloning of new conotoxin genes.
