TLDR
A simple yet robust HCV cell culture infection system based on the HCV JFH-1 molecular clone and Huh-7-derived cell lines that allows the production of virus that can be efficiently propagated in tissue culture is reported.Abstract:
The absence of a robust cell culture model of hepatitis C virus (HCV) infection has severely limited analysis of the HCV life cycle and the development of effective antivirals and vaccines. Here we report the establishment of a simple yet robust HCV cell culture infection system based on the HCV JFH-1 molecular clone and Huh-7-derived cell lines that allows the production of virus that can be efficiently propagated in tissue culture. This system provides a powerful tool for the analysis of host-virus interactions that should facilitate the discovery of antiviral drugs and vaccines for this important human pathogen.read more

TL;DR: Cardif is described, a new CARD-containing adaptor protein that interacts with RIG-I and recruits IKKα, IKKβ and IKKɛ kinases by means of its C-terminal region, leading to the activation of NF-κB and IRF3.

TL;DR: A full-length HCV genome that replicates and produces virus particles that are infectious in cell culture (HCVcc) is described, suggesting that this in vitro system will aid in the search for improved antiviral compounds.
Flaviviridae :T he Viruses and Their Replication
TL;DR: The present research attacked the Flavivirus infection through two mechanisms: Membrane Reorganization and the Compartmentalization and Assembly and Release of Particles from Flaviv virus-infected Cells and Host Resistance to Flaviviral Infection.

Characteristics of a Human Cell Line Transformed by DNA from Human Adenovirus Type 5
TL;DR: Human embryonic kidney cells have been transformed by exposing cells to sheared fragments of adenovirus type 5 DNA, and the transformed cells exhibited many of the characteristics of transformation including the elaboration of a virus-specific tumour antigen.

Replication of Subgenomic Hepatitis C Virus RNAs in a Hepatoma Cell Line
TL;DR: This work defines the structure of HCV replicons functional in cell culture and provides the basis for a long-sought cellular system that should allow detailed molecular studies ofHCV and the development of antiviral drugs.
