Worldwide, 130-150 million individuals are chronically infected with hepatitis C virus (HCV), a major cause of liver-associated morbidity and mortality worldwide. Despite recent advances in antiviral drugs that can cure some individuals, a rapid decline of the global disease burden is hampered by remarkably high treatment costs and a high number of undiagnosed infections. Moreover, a significant number of patients develop resistance and additional treatment modalities may be needed to dramatically reduce the worldwide incidence of HCV infection. The subject cell line may be a useful tool for studying the mechanism of HCV cellular entry and replication and could be incorporated into an in vitro assay to measure the effectiveness of novel HCV targeted therapies or as a system for improved propagation of HCV in culture.
By overexpressing TACSTD2 in Huh7.5 cells, scientists at the National Institute of Allergy and Infectious Diseases (NIAID) discovered that they could restore the cellular localization of two host cell HCV-entry factors that become dysregulated in hepatocellular carcinoma (HCC) cells. Overexpression of TACSTD2 makes Huh7.5 cells more broadly permissive to infection and replication by multiple HCV genotypes in comparison to the canonical Huh7.5 cell model. HCV does not replicate in malignant HCC cells, possibly caused in part by downregulation of TACSTD2 expression.
