BACKGROUND: Chronic hepatitis C is a major cause of liver fibrosis and cirrhosis.
It is generally accepted that inflammation that occurs in response to hepatocyte
infection by the hepatitis C virus (HCV) is the main mechanism that triggers
myofibroblast differentiation and stimulation in chronic hepatitis C. The aim of
this study was to determine if HCV might infect human liver myofibroblasts (HLMF)
and directly stimulate their fibrogenic activities. METHODS: We evaluated the
expression of the viral entry receptors, levels of HCV-RNA and HCV-protein and
the expression of fibrosis markers in HLMF by using quantitative PCR, western
blot and immunofluorescence analyses. Pseudoparticles (HCVpp) and cell
culture-derived HCV (HCVcc) were used to study the ability of HLMF to support
viral entry, replication and fibrosis induction. RESULTS: We showed that HLMF
expressed all known molecules of the HCV receptor complex, i.e. CD81, LDL-R,
scavenger receptor-BI, claudin-1 and occludin. These cells were also permissive
to HCVpp entry. Inoculation with HCVcc caused short-term infection of these
cells, as shown by their content in positive- and negative-strand HCV RNA, in
core and NS3 viral proteins, and by their release of core protein levels in the
culture supernatants. HCV infection stimulated myofibroblastic differentiation,
proliferation and collagen production in these cells. In addition, evidence of in
vivo infection was provided by the detection of positive- and negative-strand HCV
RNA in preparations of HLMF obtained from HCV-infected patients. CONCLUSION:
These findings indicate that HCV infection of HLMF can occur and trigger
extracellular matrix overproduction, thereby contributing to the development of
HCV-related liver fibrosis.
