Roméo Ricci, ENDOFLAMMASOME project

NLRP3 activation in endosomes: From basic mechanisms to disease

Cells in our body are constantly exposed to environmental stressors. Cells have therefore developed an intricate system of proteins that can detect these insults. Once these proteins get activated by them, they eventually induce an inflammatory response. From an evolutionary perspective, inflammation has a beneficial role as it eliminates these stressors and facilitates the repair of tissue damage caused by them. However, if inflammation persists, it can also have detrimental effects.

Our project, supported by the 'Chaires d’excellence,' centers on investigating a specific protein known as NLRP3, capable of detecting a diverse array of seemingly unrelated environmental stressors. We recently made a discovery that these stressors share a common trait: they all disrupt the composition of a specific cellular compartment known as the endosome. In fact, NLRP3 is recruited to these “stressed” endosomes thereby initiating inflammation. The understanding of this mechanism could potentially explain low-grade inflammation observed in different human diseases including obesity-associated diabetes.

Our discovery created a new research axis in the laboratory that opened fundamentally novel scientific questions. Answering them in a more comprehensive manner constitutes a very ambitious endeavor that requires state-of-the-art experimental tools and collaborations at the international level. A project of this dimension clearly requires substantial funding on a long-term basis. The “Chaire d’excellence” will provide the necessary support that will increase our international visibility at the interface of cell biology and immunology.

Albert WEIXLBAUMER, CoTransSplice Project

Decipher the coupling between mRNA splicing and gene transcription

Albert WEIXLBAUMER is one of the laureates of the ANR Chair d’excellence program. The generous funding will support his research group for 5 years, as they tackle a fundamental question: how is the coordination between transcription and splicing achieved in humans? In gene expression, transcription yields pre-mRNA, a transient DNA copy, which subsequently undergoes splicing to excise non-coding segments, resulting in mature mRNA. The process of splicing is pivotal for human proteomic diversification, as various mature mRNAs can be produced from a single pre-mRNA. Notably, splicing occurs concomitantly with transcription and is regulated by the transcription machinery. Yet, this intricate relationship remains poorly understood and will be the focus of the funded project. Ultimately, this endeavor aims to enhance our comprehension of the interplay between transcription and splicing, elucidating how humans diversify their proteome and how dysregulation of these processes may contribute to disease.

news-16140 Mon, 08 Apr 2024 14:21:44 +0200 The RNA helicase DDX5, a new regulatory protein of Sindbis virus infection /en/actualites/news/the-rna-helicase-ddx5-a-new-regulatory-protein-of-sindbis-virus-infection RNA helicases emerge as key factors regulating host-virus interactions. In this study published in “Virology Journal”, scientists have demonstrated the role of the DDX5 helicase in the replication cycle of the Sindbis virus (SINV). They were able to show that this nuclear protein is capable of relocating to the cytoplasm during SINV virus infection and directly interacting with the viral capsid, conferring a pro-viral action. RNA helicases are emerging as key regulators of viral infections. They are essential enzymes for the unfolding of RNA structures and play a crucial role in many cellular processes involving RNA, as well as in regulating various stages of viral cycles.

In this study, researchers investigated the impact of the human RNA helicase DDX5 on SINV infection, a model virus for studying other mosquito-transmitted emerging pathogens such as the Chikungunya virus. Using imaging and RNA immunoprecipitation approaches, they highlighted for the first time that DDX5 has the peculiarity of relocating from the nucleus to the cytoplasm of cells during infection by interacting with viral RNA. Furthermore, the analysis of DDX5 interactome by mass spectrometry in SINV-infected human cells identified new cellular and viral partners. The researchers identified a direct interaction between DDX5, its known cofactor DDX17, and the viral capsid. Scientists were able to demonstrate that the absence of DDX5 and its cofactor DDX17 in the cell reduces SINV infection. Conversely, overexpression of DDX5 has a positive impact on the virus, underscoring the central role played by DDX5 in host-virus interaction during the infectious cycle of SINV.

These results not only highlight that DDX5 is a novel host factor hijacked by SINV but also broaden our understanding of the roles played by DDX5 and DDX17 as regulators of viral infections. As the inhibition of both DDX5 and DDX17 reduces virus levels, further investigations are needed to better characterize these factors as potential targets for future antiviral therapies.

  • You can propose a single team project (supported by Cluster Research (/LabEx) funding). As a reminder, each Cluster Research has to organise its internal scientific priorities (eligibility, number of fellowships...) within the common Graduate School guidelines.

  • You can submit a collaboration project involving two teams from two different IMCBio Cluster Research (INRT, NetRNA, MitoCross, HepSYS). Up to two doctoral contracts will be supported by the IMCBio Graduate School funds in 2024. Important: note that this year again, to allow applicants to get a better grasp of these collaboration projects and identify a main contact, one of the host team will be presented as the main project coordinator as the second team as the collaborator. The project needs to rely on strong collaboration to warrant support by the IMCBio Graduate School.

  • You can submit a project with your own-funding (whatever the source of funding already acquired). 

And this year we propose you a new possibility

  • You can submit a team-platform collaboration project involving, a research team and a technology platform if possible from two different IMCBio Cluster Research (INRT, NetRNA, MitoCross, HepSYS, note that this is not an absolute criteria). Up to three doctoral contracts will be supported by the IMCBio Graduate School funds in 2024. These projects will have for objective the development of a new method (not incremental progress or implementation of existing processes) that have the potential to result in a methodological leap forward associated to technology transfer (in this vein a link with a private company could be a plus). Note that this action is intended primarily to support to develop new technologies and not an alternative to support existing team projects. Importantly, for these new type of projects, a validation step by the IMCBio executive committee will occur before posting of selected projects the IMCBio PhD Call web site. The PhD student supervision has to be assumed by an HDR identified as the main contact (team or platform) with the second partner identified as the collaborator.

As a reminder: each Cluster Research (/LabEx) has to organize its internal scientific priorities for LabEx funded grants following the common Graduate School guidelines.

CoLoC-seq, pour bien localiser les ARN dans la cellule

Au sein d’une cellule, on trouve différents composants, ou organites, individualisés par une membrane (noyau, mitochondrie, appareil de Golgi, …). Pour chaque organite, les généticiens ont besoin de déterminer la localisation précise des ARN produits à partir de l’ADN. En effet, leur localisation correcte est nécessaire à l’expression des gènes. Problème, les techniques utilisées, quand elles reposent sur l’utilisation d’enzymes de type RNases, confondent souvent les ARN de l’organite étudié, dits « résidents », des ARN produits ailleurs, dits « contaminants ». Pour les distinguer, les chercheurs proposent CoLoC-seq, nouvelle méthode qui repose sur la cinétique enzymatique et une modélisation mathématique.

SFPQ, protéine détournée par le virus SINV... CQFD !

Les virus sont des parasites obligatoires, qui dépendent de la cellule qu’ils infectent pour multiplier leur génome et se propager. Lors de la réplication, les virus à ARN produisent un ARN double brin (ARNdb), qui est perçu par la cellule comme signal de danger et va déclencher la réponse antivirale. Les virus ont mis au point diverses stratégies pour contourner cette réponse. Il est par conséquent crucial d’identifier les protéines cellulaires que le virus détourne dans ce but. Les scientifiques ont conduit leur étude sur le virus de Sindbis. Parmi les protéines reconnaissant l’ARNdb viral, ils ont pu identifier la protéine SFPQ (splicing factor, proline-glutamine rich) comme facteur pro-viral.

news-15763 Wed, 15 Nov 2023 09:59:22 +0100 Portrait of the new manager at IMCBio /en/actualites/news/portrait-of-the-new-manager-at-imcbio Welcome to Gwenaëlle Graulier! "A microbiologist by training, I began my career as a research engineer in the Biotechnology and Cell Signalling Laboratory after studying at the University of Strasbourg (IUT Louis Pasteur and then the Faculty of Life Sciences). I then decided to try my hand at the great adventure of a PhD in the same laboratory, working on a pathogenic bacterium, its infection in people with cystic fibrosis and its relationship with iron. Following this, and charmed by teaching, I was given the opportunity to teach a Biology Engineering degree at the IUT Louis Pasteur, where I taught various subjects related in one way or another to molecular biology. I've now moved on to another facet of university education as head of EUR IMCBio."

This structure is maintained by a recycling process that eliminates damaged or useless parts. However, it tends to become dysregulated in muscle cells with advancing age. To better understand the consequences in muscle aging, Minchul Kim and Marcus Rüegg, researcher at the Biozentrum of the University of Basel, have launched a joint research project.

With support from IMCBio, we plan to host 20 students registered in European universities (external to Strasbourg) and up to 20 local students from Strasbourg. During their stay, students will have the opportunity to visit and listen to presentations from the different IMCBio components and partners with the following tentative program:

Day 1 - Esplanade/IBMC-IBMP-GMGM

Day 2 - Illkirch/IGBMC

Day 3 - Hospital/HepSYS/Life Science Faculty
This first event is being organized with the help of a team of 10 PhD students*, they might contact you or people in your team to participate to presentations.

Agenda
news-15411 Thu, 22 Jun 2023 10:54:48 +0200 2023 μNET Strasbourg meeting /en/actualites/news/2023-mnet-strasbourg-meeting On June 23, 2023, a one-day seminar will be held with Dr. Thomas Kehl-Fie (University of Illinois at Urbana-Champaign, USA) in the IBMC seminar room. The main objective of his research is to understand how the opportunistic pathogen Staphylococcus aureus obtains and copes with the absence of essential inorganic nutrients, such as metals, during infection.

This plenary lecture will be followed by short presentations by members of µNET Strasbourg, a network of recently recruited researchers in Microbiology. This network, still in its infancy, was born in Marseille and has since been emulated in several major cities, including Strasbourg, Lyon and Toulouse. The idea of the network is to help new microbiologists get their bearings, support each other at the start of their careers, encourage scientific and practical exchanges and facilitate the integration of new researchers into the Strasbourg and national landscape.

Please confirm your attendance by following the link below:  https://evento.renater.fr/survey/participation-to-net...-ggsfdtpe


We hope to see many of you,
David Lalaouna and Pascale Romby
