Postdoc Position in Virology (1yr, renewable) We are launching M+RVL, a new research group dedicated to better understanding the
fundamental mechanisms of positive-strand RNA virus replication. Supported by the LabEx NetRNA
research cluster, the team is based within the Mosquito Models of Innate Immunity (M3I) unit at the
Institute of Molecular and Cellular Biology (IBMC) in Strasbourg, France. Strasbourg is a lively city in
northeastern France that offers a high quality of life, a vibrant university system, and a historic city center
at the heart of Europe.
Research Focus Replication organelles (ROs) are membrane-bound compartments that drive genome
replication in positive-strand RNA viruses. Mosquito-borne viruses must assemble ROs in both mosquito
and vertebrate hosts, which are separated by hundreds of millions of years of evolution. While structural
biology has revealed the architecture of ROs in human cells, structure alone cannot explain their
assembly, dynamics, and host-specific interactions, highlighting the need for integrative approaches.
To address this gap, M+RVL integrates high-throughput genetics, proteomics, and computational
modeling to dissect the mechanisms governing RO formation and function across hosts.
Research Leadership The group is led by William Bakhache, Ph.D.

Essential Skills: Strong background in virology, molecular biology, and biochemistry techniques.
Desired Experience: Experience handling BSL-3 pathogens; expertise in computational biology
(e.g., NGS analysis, proteomics data analysis, structural modeling).
How to Apply Please send a single PDF containing a cover letter (detailing past and future research
interests), a CV, and contact information for two references to williambakhache@hotmail.com.

SpaceBar enables single-cell-resolution clone tracing with imaging-based spatial transcriptomics Nature Methods - SpaceBar is a cellular barcoding strategy for simultaneous analysis of cell clonal and spatial identities.

Excited that SpaceBar is now out in Nature Methods!πŸ₯³

We combined clone tracing with spatial transcriptomics to untangle what drives gene expression in tumors: a cell's identity or its neighborhood?

Most genes were driven by location, but some showed strong clonal patterns.

This parallels ongoing work in the treatment of cancers and bacteria showing that competitive inhibition and ecological interaction mediated by drug dosing can improve population control.

Understanding this feedback could allow us to design more evolution-proof therapies by maintaining therapeutically useful social interactions over time.

@alexrob.bsky.social finds that neutralizing fewer viruses with weaker drugs can paradoxically lead to less resistance and lower viral loads.

10.12.2025 21:07 β€” πŸ‘ 1    πŸ” 0    πŸ’¬ 1    πŸ“Œ 0

The point is much broader than poliovirus and pocapavir: if we're trying to design therapeutics that exploit social interactions between viruses, we need to account for the effects of therapeutic success in diminishing those interactions.

Label: High density. Image: multiple sensitive and resistant genomes coinfect cells and produce hybrid capsids with resistant and sensitive subunits which mostly fail to pass through a selective screen. 

Bottom:

Label: Low density. Image: single sensitive and resistant genomes in cells and produce fully resistant or sensitive capsids. Fully resistant genomes pass successfully through a selective screen.

The answer? Sometimes! The key variable is the density of the viral population. When viruses coinfect often, interference is effective at arresting resistance evolution.

BUT, if the drug works well, it reduces viral density, ultimately allowing resistance to escape this interference.

In theory, this means that sus viruses should prevent resistance from spreading intra-host while it's rare.

Does it work? @alexrob.bsky.social built a poliovirus replication model to probe the impact of intra-cellular resource sharing, and validated it against experimental and clinical data.

Pocapavir binds an oligomeric poliovirus capsid composed of 60 subunits.

Mutations can change this subunit's shape and prevent binding. However, if capsids contain both susceptible AND resistant subunits, drug can bind anyway.

As a result, sus viruses can sensitize res ones when they share a cell.

So excited to share this work led by @alexrob.bsky.social with Ben Kerr!

We investigated a poliovirus capsid inhibitor that exploits a breakdown in the genotype-phenotype map to prevent drug resistance evolution. Or does it?

See Alex's thread, but a few extras:
