Resumen en inglés | Hepatitis C virus (HCV) infection is an important risk factor for the development of liver fibrosis and progression to cirrhosis. Liver transplantation as terminal treatment option for liver disease requires life-long immunosuppression. However, immunomodulatory therapy may promote reinfection and renewed fibrogenesis. Immunosupressive agents may also affect the life cycle of hepatic stellate cells (HSC), the main source of extracellular matrix. We thus aimed to characterize the effects of three common immunosuppressive agents on HSC apoptosis with or without engulfment of HCV infected apoptotic bodies. Material and methods. LX2 cells were incubated with three different immunosuppressants (rapamycine, mycophenolic acid or cyclosporine A) and co-incubated for 24 and 48 h with apoptotic bodies (AB), produced from Huh7 cells or from Con1 cells (Huh7-cells containing a subgenomic HCV replicon). The engulfment of AB was confirmed by immunofluorescence staining. HSC viability, apoptosis rate and expression of profibrogenic and proapoptotic genes were quantified. Results. In LX2 cells that engulfed Con1 AB, the treatment with mycophenolic acid induced HSC apoptosis and reduced collagen 1alpha 1 expression compared to cylosporine A or rapamycine treatment. In conclusion mycophenolic acid is a potent inducer of HSC apoptosis and attenuates HSC activation and consecutively fibrogenesis in HCV infection. Translational studies will need to confirm these mono-culture results in vivo |
