Norovirus Capsid Assembly

Norovirus Capsid Assembly

During my PhD, under the guidance of Dr. Stephane Bressanelli and Dr. Yves Boulard,  I will try to better understand the Norovirus Capsid Assembly. My PhD lab is the newly created Institute for Integrative Biology of the Cell (I2BC). I will be located at the CEA (Commissariat à l’énergie atomique et aux énergies alternatives) Institute of Biology and Technology Saclay (iBiTec-S) since iBiTec-S houses part of the I2BC Department of Biochemistry, Biophysics and Structural Biology for the time being.

Aim of this project:

This project aims to better understand the Norovirus Capsid Assembly. The Norovirus Capsid is formed by 180 copies of one protein : VP1. It is a quite simple system, but in-vivo, the capsid is very efficient to assemble and disassemble itself. However, experimentally, the capsid transit from a non-stable state: while the capsid should have been destroyed, it manages to form properly.
My project is to use Molecular Dynamics methods to understand what happens during this transition state and how the norovirus capsid manage to assemble itself.


Noroviruses are very resilient and biodisponible viruses. They are gastroenteritis viruses transmitted by the fecal-oral route, so they are transmitted by ingestion. Understanding their assembly mechanisms may allow development of new antivirals. Furthermore, their capsids can envelop more than RNA, so a better understanding of the Norovirus Capsid Assembly can be very useful for drug delivery.

This PhD Project is financed by the Ile-de-France under the Field of ​​Interest Major « Human Infectious Diseases: Mechanisms, Risks and societal impact » (Pathologies infectieuses humaines : mécanismes, risques et impact sociétal)

Pictures, animations and first results.

Only some videos are present since the results are not published yet.

  • This video is an update of the first « capsid description ». It was made for « My thesis in 180s – Doctoral School edition ».
  • This videos was created for a talk on the maison de la simulation of Saclay on a « image wall (8K – 3D – 4.3m on 2.3 : It aims to have a better view and comprehension of the Norovirsus Capsid.
