Seminars

Conferences at IRIM

All seminars and conferences at the IRIM laboratory take place every Friday at 11:00 AM in the meeting room "Marcel Dorée". Seminars are either presented by the IRIM teams (internal seminars) or given by external speakers (invited seminars, see below).

In 2019, the IRIM has also launched a new seminar series, aiming at providing experience and feedbacks from people with successfull and interesting careers outside academia, and who previously did a PhD and a postdoc (or several postdocs!). The 'Career outside academia’ seminars will be held for PhD students and postdocs only, in a informal and relaxed context and any type of questions/discussions will be welcome. More information here.

Future seminars:

  • Dr. Philippe Benaroch "Host-HIV interplay in human primary myeloid cells" - 22nd November 2019

Philippe Benaroch is research director at the CNRS and heads the team “Myeloid cells and immunity” within the Department of Immunology at the Institut Curie in Paris. He will present recent work and unpublished data regarding a recently identified blood dendritic cell subset, its unique relationship with HIV and some of its shared properties with infected macrophages.

Philippe Benaroch is particularly interested by myeloid cells that represent a very ancient form of cellular immunity against pathogens and tumor cells. Myeloid cells are very plastic, endowed with an ever-growing list of functions in innate and adaptive immunity. How myeloid cells crosstalk with HIV and tumor cells and how this interplay is regulated remains to be established at the molecular level and represent the focus of his lab.

  • Dr. Sarah Gallois-Montbrun (Institut Cochin, Paris"Non-canonical Roles of Argonaute proteins in HIV-1 viral RNA expression" - 13th December 2019

Summary of the talk: During its replication, HIV-1 produces more than 50 different transcripts coding for all the proteins necessary for viral particles assembly. Balanced production of viral isoforms is highly regulated both temporally and spatially. Current research in my group aims at characterizing the role of viral and cellular factors involved in HIV-1 RNA production. In particular, we investigated the role of the miRNA pathway and demonstrated that key proteins of these pathway, Argonaute 1 and Argonaute 2, participate at different levels of viral RNA production independently of the presence of miRNA. In parallel, we recently developed a long-read sequencing assay to quantify production of HIV-1 isoforms and to decipher the cascade of splicing events taking place at early time points after infection. 

Dr Gallois-Montbrun's minibiography: After completing her PhD studies at Pasteur Institute Paris in 2004 on cellular metabolism of anti-HIV-1 drugs, she undertook post-doctoral training with Prof Michael Malim at King’s College London. There she focused on characterizing cellular protein and RNA partners of APOBEC3G and APOBEC3F, two HIV-1 restriction factors. She was recruited as Inserm research scientist at Cochin Institute in 2009.  Since then, her group has aimed at dissecting mechanisms regulating HIV-1 RNA fate and how these impact on viral replication.

 

Past seminars:

  • Dr. Lise Chauveau (Oxford university, UK) "The immune system’s Trojan horse: Using cGAMP-loaded VLPs for vaccination"  - 11 Octobre 2019 2pm

Dr Lise Chauveau is interested in how viruses induce an immune response, the type of response induced and how viruses may counteract it. She studied Biology at the Ecole Normal Superieure de Lyon where she obtained a Master degree in 2012. She then moved to the Pasteur Institute in Paris to complete a PhD in the laboratory of Prof Olivier Schwartz in 2016. There, she studied factors influencing the ability of HIV-1 and HIV-2 to infect cells of the immune system, CD4 T cells and dendritic cells. This is where her interest in antiviral immunity and how viruses might modulate it sparked. She is now a postdoctoral researcher with Dr Jan Rehwinkel at the Weatherall Institute of Molecular Medicine, University of Oxford, UK. She currently works on an original vaccination strategy using HIV-derived virus-like particles that incorporate an innate immune messenger (cGAMP) to induce potent and protective immune response against viruses.

 

  • Prof. Ricardo Soto-Rifo (Universidad de Chile) "The complex life of HIV-1 full-length RNA" - Tuesday 1st of october 2019

Dr. Soto-Rifo has been always interested in the molecular and cellular mechanisms controlling gene expression in Eukaryotes with a special emphasis in RNA viruses as study models. Dr. Soto-Rifo studied biochemistry at Universidad de Santiago de Chile and then moved to France where he obtained a Master in Sciences degree from Université Claude Bernard Lyon-1 in 2006 and then a Ph.D in Life Sciences from Ecole Normale Supérieure de Lyon in 2010. He worked at the Human Virology Department (currently the International Center for Infectiology Research, CIRI) under the supervision of Dr. Théophile Ohlmann on the translational control of the HIV-1 and HIV-2 genomic RNA. During his post-doctoral training at Dr. Ohlmann's lab, Dr. Soto-Rifo worked on the remodeling and localization of the messenger ribonucleoprotein complexes (mRNPs) containing the HIV-1 genomic RNA by analyzing the role of the DEAD-box RNA helicase DDX3 in these processes. In 2013, he moved to Biomedical Sciences Institute at Universidad de Chile Faculty of Medicine to start his own laboratory at the Virology Program. Since then, Dr. Soto-Rifo's reasearch has been mainly focused in understanding the mechanisms involved in RNA metabolism during HIV-1, HIV-2, respiratory syncytial virus and Zika virus replication.

The presentation will be focused on the role of the RNA modification N6-methyladenosine (m6A) and its associated cellular machinery in defining the cytoplasmic destiny of the HIV-1 genomic RNA during the late steps of the viral replication cycle.

 

  • Dr. Pierre-Olivier Vidalain (CIRI) "Searching for chemical activators of the interferon response : surprises from a chemobiological approach" - 13th September 2019

Pierre-Olivier Vidalain, Research Director, CNRS. After his Ph.D in immunology (Ecole Normale Supérieure de Lyon), Pierre-Olivier joined Marc Vidal's team (Harvard Medical School, Boston) where he was trained to high-throughput screening techniques and protein-protein interaction analysis. Recruited in 2005 at the CNRS, he worked successively at the Institut Pasteur and the Université Paris Descartes where he studied interactions between viral and cellular proteins and developed multiple assays for the identification of antiviral compounds targeting host factors. He has a special interest in the immunomodulatory properties of small compounds inhibiting the pyrimidine biosynthesis pathway. In January 2019, he joined the International Infectiology Research Center in Lyon to continue his work at the interface between innate antiviral immunity, metabolism and chemobiological approaches.

 

  • Dr. Jost Enninga (Institut Pasteur, Paris) "Subversion of infection associated macropinosomes drives the intracellular niche formation of bacterial pathogens" - 5th July 2019

Jost Enninga heads the research unit « Dynamics of host-pathogen interactions » within the Department of Cell Biology and Infection at the Institut Pasteur in Paris. He performed his Ph.D. studies in the Laboratory of Cell Biology at the Rockefeller University, New York, under the supervision of Dr. Guenter Blobel. There, he focused on how viruses subvert host cellular trafficking processes. Afterwards, Jost moved to the Institut Pasteur in Paris in 2004 to study the early events of bacterial host cellular invasion with Dr. Philippe Sansonetti and Dr. Guy Tran Van Nhieu. Between 2008 and 2012, Jost built up his own junior team at the Institut Pasteur, and he heads his current research unit since 2013. His team investigates the intracellular niche formation of different bacterial pathogens, including Shigella and Salmonella.  Main questions are membrane trafficking subversion by the pathogens, and how specific intracellular localizations trigger distinct immune responses. His research unit develops imaging-based technologies that allow the analysis of host-pathogen interaction dynamics with unprecedented spatiotemporal resolution.
