Relevance of Rab Proteins for the Life Cycle of Hepatitis C Virus

Résumé fourni par la source

Although potent direct-acting antiviral drugs for the treatment of chronic hepatitis C virus infection are licensed there are more than 70 million individuals suffering from chronic HCV infection. In light of the limited access to these drugs, high costs and a lot of undiagnosed cases it is expected that the number of HCV cases will not decrease worldwide in the next years. Therefore, and due to the paradigmatic character of HCV for deciphering the crosstalk between viral pathogens and the host cell, characterization of HCV life cycle remains a challenge. HCV belongs to the family of Flaviviridae. As an enveloped virus HCV life cycle depends in many steps on intracellular trafficking. Rab GTPases, a large family of small GTPases, play a central role in intracellular trafficking processes controlling fusion, uncoating, vesicle budding, motility by recruiting specific effector proteins. This review describes the relevance of various Rab proteins for the different steps of the HCV life cycle.
