Viral infections are rising every day, and viruses appear to be the most dangerous pathogens in the world. Hepatitis C virus (HCV) is accepted as one of the major destructive factors of promoting severe hepatic disorders by infecting more than 180 million individuals throughout the world. Chronic infection caused by HCV poses a serious global health emergency and appears to be a powerful threat to humanity. Almost 20 years have passed since the disclosure of HCV, but even now, treatment preferences remain limited. Humans are born with a rapid and nonspecific mechanism to prevent viral attacks through Toll-like receptors (TLRs), which are evolutionary conserved cellular activator proteins responsible for recognizing specific components present on penetrating microbes and viruses. Recent research efforts in TLR biology suggest that targeting the TLRs and their signaling pathways during HCV infection could contribute to novel therapies against HCV. The mobilization of TLRs boosts antiviral communication and integrates the development of long-lasting acquired immune responses to limit viral pathogenesis. Both activation and suppression of TLRs are necessary for the efficient treatment of HCV. For the proper management and eradication of HCV, novel drugs that target TLRs and their signaling pathway are needed. This review summarizes the role of TLR signaling in HCV infection and treatment.
