The Pasteur Museum is housed in the apartment where Louis Pasteur spent his final seven years and offers a rare behind-the-scenes look at the living and working environment of the world-renowned scientist. Visitors can gain a unique insight into his everyday life alongside his wife and can admire his rich and diverse scientific work.
The Institut Pasteur’s scientific strategy focuses on developing original and innovative topics and promoting interdisciplinary and multidisciplinary cooperation and approaches. The Institut Pasteur teams have access to the technological resources needed to speed up and further improve the quality of their outstanding research.
Ever since the introduction of the world’s first "Technical Microbiology" course in 1889, teaching has been a priority for the Institut Pasteur. The Institut Pasteur has an international reputation for quality teaching that attracts students from all over the world who come to further their training or top up their degree programs.
The mission of the Industrial Partnership team is to detect, promote, assist and protect the inventive activities from research (inventions, know-how and biological materials) conducted at the Institut Pasteur (and in some Institutes of its international network), and transfer there to industrial and/or institutional partners, in order to serve the patient needs and for the benefit of the society, as well as to contribute to sustainability of the Institut Pasteur’s resources.
With international courses, PhD and postdoctoral traineeship, each institute of the Institut Pasteur International Network (RIIP) contributes to the transmission of knowledge with the training of young researchers all around the world. In this context, doctoral and postdoctoral programmes, study and traineeship fellowships are available to scientists. Alongside training, dynamism and attractiveness of RIIP will result in the creation of 4-year group for the young researchers.
Chikungunya : discovery of a human-specific factor involved in the virus replication
Scientists from the Institut Pasteur, Inserm and CNRS, have identified a human-specific factor involved in the replication of Chikungunya virus which accounts for the species specificity of this virus. Chikungunya virus is an emerging virus that in 2005 caused, for the first time, an outbreak in La Réunion island, a French overseas district where more than 30% of the population was infected, and has recently emerged in temperate regions of Europe. The identification of this new host factor enriches our understanding of the molecular bases of Chikungunya virus infection, which were characterized so far. This work also paves the way for the development of a more relevant humanized animal model to better understand the pathophysiology of infection. This research has been published online on April 26, at the European Molecular Biology Organization reports (EMBO reports).

Chikungunya virus was first identified in Tanzania in the 1950s and emerged in the islands of the Indian Ocean in 2005 where it caused a large outbreak, most notably in La Réunion island. In 2007, this virus was imported to Europe, causing an outbreak in Italy. In late summer 2010, the two first autochthonous cases were reported in the French Riviera.
The molecular mechanisms of Chikungunya virus infection in human cells have been poorly characterized. Scientists at the Institut Pasteur, Inserm and CNRS, under the leadership of Marc Lecuit, head of the Biology of Infection Unit at the Institut Pasteur in Paris, have made a significant advance: they have identified a human-specific intracellular molecular factor called NDP52 that is involved in the replication of Chikungunya virus. The scientists have demonstrated that in human cells, NDP52 is able to bind to a protein of Chikungunya virus, nsP2, and that this interaction promotes the replication of the virus inside its target cells, thereby contributing to the development of human Chikungunya virus infection. In contrast, mouse NDP52 does not interact with nsP2, and NDP52 therefore does not promote infection in murine cells.
In 2008, the team headed by Marc Lecuit had developed the first animal model to experimentally reproduce the human disease caused by Chikungunya virus. This animal model has since allowed a better understanding of the physiopathology of infection, and has enabled the identification of Chikungunya virus target cells and tissues to test the efficacy of preventive and curative approaches. The discovery of the role of the human factor NDP52 in Chikungunya virus infection opens new avenues for the development of a humanized animal model, which would be instrumental for deeper understanding of the pathophysiology of Chikungunya virus infection.
