Offer Description

Two fully funded PhD positions in the Michaux lab - Dynamics of Epithelial Polarity - IGDR, Rennes, France

The two positions are funded by the Doctoral Network SurfEx , a Horizon Europe MSCA project.

The apical membrane of the intestinal epithelium presents a network of actin- based microvilli, called the brush border, which is essential for food absorption, secretion and interactions with the microbiome. In these projects, we propose to molecularly and functionally characterize intestinal microvilli in a living organism, using C. elegans as a model, from normal growth to pathological atrophy and regeneration.

Project 1: Functional characterization of the formation and maintenance of C. elegans intestinal microvilli – Supervised by Anne Pacquelet

We recently started to describe the growth and dynamics of microvilli during C. elegans development (Bidaud-Meynard et al , PMID: 34704594) . We will next characterize how major microvilli components contribute to microvilli growth and maintenance and how their dynamic localization and behaviour are regulated during microvilli formation. To this end, we will use loss of function approaches and analyse the role of microvilli factors using a combination of super-resolution imaging, FRAP measurements and food absorption experiments. We will investigate the role of microvilli factors that we and others have already identified, as well as new microvilli components identified by our collaborator Mike Boxem (Utrecht University, Utrecht, Netherlands) using a proteomic approach. This project will lead to the first in-depth functional characterization of microvilli growth and maintenance in a living organism during embryonic and post-embryonic development, paving the way to future studies as a model for human intestinal diseases.

Project 2: Dynamics of C. elegans intestinal microvilli atrophy and regeneration – Supervised by Grégoire Michaux

In humans, intestinal microvillus atrophy can be inherited or acquired and is associated with food malabsorption, persistent diarrhoea and a severe morbidity. We propose to identify new therapeutic options to treat microvillus atrophy, whether hereditary or acquired. We recently established several genetic and pathological models mimicking inherited and acquired microvillus atrophy in C. elegans. In this project, we will first characterise microvillus atrophy and natural regeneration in these models, using state-of- the-art genetic tools and live super-resolution microscopy. We will then explore the regeneration of microvilli and compare this process to their normal developmental growth. Finally, we will test a role for the gut microbiome in improving regeneration, in a collaboration with the group of Buck Samuel (Baylor College of Medicine, Houston, USA).

Start Date : 1 December 2023
