Topic description
Le virus de l'hépatite E (VHE) de génotype 3 (VHE-3) est responsable d'hépatites chroniques chez les patients transplantés. Ce virus infecte le foie et l'intestin et circule entre ces deux organes via le sang et la lumière intestinale. Le traitement repose sur la ribavirine, qui semble bloquer efficacement la libération de virus vers le sang mais pas vers la lumière intestinale. Nous émettons l'hypothèse que cette production virale persistante sous traitement pourrait contribuer à une réinfection de l'hôte et aux échecs de traitement. Le premier objectif de cette thèse est de préciser l'impact du traitement antiviral sur la production de virus par le foie et l'intestin, en direction du sang et de la lumière intestinale. Le second objectif est d'étudier l'impact du flux sanguin et intestinal sur l'infection par le VHE et sur l'efficacité du traitement. Ce travail reposera sur des modèles de foie et d'intestin sur puce en système microfluidique.

Hepatitis E virus (HEV) genotype 3 (HEV-3) is responsible for chronic hepatitis in transplant patients. This virus infects the liver and the intestine and circulates between these two organs via the bloodstream and the intestinal lumen. Treatment relies on ribavirin, which appears to effectively block viral shedding into the blood but not into the intestinal lumen. We hypothesize that this persistent viral production during treatment could contribute to reinfection of the host and treatment failure. The primary objective of this thesis is to clarify the impact of antiviral treatment on viral production by the liver and intestine, directed toward the bloodstream and the intestinal lumen. The second objective is to study the impact of blood and intestinal flow on HEV infection and on treatment efficacy. This work will rely on liver and intestinal-on-a-chip models in a microfluidic system.
