Suppression of Coronavirus Replication by Cyclophilin Inhibitors
Coronaviruses infect a variety of mammalian and avian species and cause serious diseases in humans, cats, mice, and birds in the form of severe acute respiratory syndrome (SARS), feline infectious peritonitis (FIP), mouse hepatitis, and avian infectious bronchitis, respectively. No effective vaccine or treatment has been developed for SARS-coronavirus or FIP virus, both of which cause lethal di...
متن کاملCyclophilins as Modulators of Viral Replication
Cyclophilins are peptidyl-prolyl cis/trans isomerases important in the proper folding of certain proteins. Mounting evidence supports varied roles of cyclophilins, either positive or negative, in the life cycles of diverse viruses, but the nature and mechanisms of these roles are yet to be defined. The potential for cyclophilins to serve as a drug target for antiviral therapy is evidenced by th...
متن کاملCyclophilin inhibitors block arterivirus replication by interfering with viral RNA synthesis.
Virus replication strongly depends on cellular factors, in particular, on host proteins. Here we report that the replication of the arteriviruses equine arteritis virus (EAV) and porcine reproductive and respiratory syndrome virus (PRRSV) is strongly affected by low-micromolar concentrations of cyclosporine A (CsA), an inhibitor of members of the cyclophilin (Cyp) family. In infected cells, the...
متن کاملCyclophilin Inhibitors as a Novel HCV Therapy
A critical role of Cyclophilins, mostly Cyclophilin A (CyPA), in the replication of HCV is supported by a growing body of in vitro and in vivo evidence. CyPA probably interacts directly with nonstructural protein 5A to exert its effect, through its peptidyl-prolyl isomerase activity, on maintaining the proper structure and function of the HCV replicase. The major proline substrates are located ...
متن کاملCyclophilin function in Cancer; lessons from virus replication.
Cyclophilins belong to a group of proteins that possess peptidyl prolyl isomerase activity and catalyse the cis-trans conversion of proline peptide bonds. Cyclophilin members play important roles in protein folding and as molecular chaperones, in addition to a well-established role as host factors required for completion of the virus life cycle. Members of the cyclophilin family are overexpress...
