A postdoctoral position is available in the laboratory of Dr. Clarisse Berlioz-Torrent at the Institut Cochin in Paris. This opening is funded by the ANRS (Agence Nationale de Recherche sur le SIDA et les Hépatites Virales).

 

Overview

Autophagy is a highly conserved degradative pathway that maintains cellular homeostasis, responds to pathological processes and combats infections. Growing evidences demonstrate that ATG proteins, which control autophagy, also regulate non-autophagy-related cell functions, such as phagocytosis of pathogens, membrane remodeling, antiviral activity or specialized secretion. These recent advances led us to explore the non-canonical function of ATG proteins in HIV-1 replication cycle. In this context, we showed that HIV-1 engages a non-canonical autophagic pathway, reminiscent of LC3-associated phagocytosis (LAP), to counteract BST2 restriction on HIV-1 release. BST2 is a restriction factor that reduces HIV-1 dissemination by tethering HIV-1 virions at the cell surface.

 

Project

With more than 700000 deaths due to this infection in 2019, HIV-1 is still a major global public health issue. It is therefore crucial to better characterize the interactions with cellular proteins that govern the replication cycle of HIV-1 in order to propose new therapeutic targets. In line with our ongoing work, the candidate will identify cellular cofactors required for HIV dissemination, related to non-canonical function of ATG proteins.

Applicants for this position should have strong knowledge and expertise in virology, protein biochemistry, cellular biology, molecular biology and/or the field of autophagy. While previous experience in these fields is a plus, we also welcome candidates from other fields, motivated to make the transition to HIV research. Main activities will be: cell tissue culture and viral infection in BSL2 and BSL3 environment, Imaging (confocal microscopy, live imaging, electronic microscopy), cellular fractionation and compartment isolation, protein complex purification, mass spectrometry analysis.
