Highlights
During last years our research group has been particularly focused on identifying
useful non-invasive prognostic biomarkers of chronic hepatitis C (CHC) progres-
sion to cirrhosis and hepatocellular carcinoma (HCC). We are also interested in
understanding how the hepatitis C virus (HCV) interacts with target cells, with
particular emphasis on the role of the cellular factors implicated in different steps
of the viral life cycle.
The altered expression of multiple angiogenic and fibrogenic-related factors du-
ring the course of CHC provides a valuable tool for the non-invasive assessment
of liver fibrosis, clue for clinical decision-making. Among other clinical and demo-
graphic variables, peripheral levels of angiopoietins correlated significantly with
hepatic fibrosis. Such finding allowed us to develop a novel index for non invasive
evaluation of liver fibrosis, AngioScore, which was further validated in an indepen-
dent series of patients with CHC.
Monocytes, essential precursors of antigen-presenting cells, notably contribute
to the pathogenesis of chronic inflammatory diseases and cancer. Interestingly,
we detected in the peripheral blood of CHC patients a significant increment of a
subtype of monocytes with marked proangiogenic properties but notable immu-
nosuppressive nature able to express the angiopoietin receptor Tie2, highlighting
the relevant role of Angiopoietin/Tie-2 axis on the regulation of inflammatory res-
ponse during the progression of chronic liver diseases.
In addition, we have characterized the significance of certain genetic variants
of ISGs and HDACs for the optimization of IL28B predictive value of therapeutic
13
response of CHC patients; interestingly some of them were markedly related to 20
fibrosis progression (Patents: ES-2422874_A1 and ES-2423154_A1).
