[Study of hepatitis C virus leukotropism by characterization of viral quasispecies in the liver transplantation setting]. / Etude du leucotropisme du virus de l'hépatite C par analyse des quasi-espèces virales dans le contexte de la transplantation hépatique.

ABSTRACT

Besides hepatocytes, representing the main replication site of hepatitis C virus, peripheral blood mononuclear cells also represent a crucial target for viral infection. Hepatitis C virus compartmentalization (i.e., non-random distribution) of viral variants between plasma and peripheral blood mononuclear cells, more frequently observed in liver transplant patients compared to non-transplanted patients, makes liver transplantation an interesting model for the analysis of hepatitis C leukotropism. This article aims to present, firstly, in clinical and biological features arguing favour of hepatitis C virus infection leukotropism and, secondly, to review current knowledge about compartmentalization between plasma and peripheral blood mononuclear cells, especially in the liver transplantation setting.
