hronic infection by the hepatitis C virus (HCV) is a major
cause of liver diseases, predisposing to liver fibrosis
and end-stage liver complications, the most serious being
hepatocellular carcinoma. Fibrotic tissue remodeling can exert
a pronounced effect on cancer initiation and growth. Liver
fibrosis is characterized by an overly abundant accumulation
of components of the hepatic extracellular matrix (ECM),
such as collagen and elastin fibers, with consequences
on the biomechanical and biochemical properties of this
microenvironment. However, the molecular mechanisms
linking infection to fibrogenesis still remain unclear. Here
I will focus on the pericellular matrix or glycocalyx, the
transition zone between the cell membrane and the ECM.
In this zone, I will more specifically focus on heparan sulfate
proteoglycans (HSPG), key molecules which bind cytokines
and growth factors and modulate their bioavailability in the
ECM. Our data suggest that HCV induces major alterations of
HSPG metabolism, and a reshuffle of the pericellular matrix
to provide a microenvironment favorable for viral replication
and persistence. These key events of HCV pathogenesis could
contribute to fibrogenesis.
