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.
Research teams from the Institut Pasteur, the CNRS, and Inserm have recently characterized the structure and mechanism of action of an antibody that successfully neutralizes all four strains of the dengue virus in mice models. Their groundbreaking work represents major progress for research efforts that hope to develop an effective vaccine to combat this disease. This study was published February 8, 2012 in the scientific journal Structure.
Paris, February 10th, 2012
The variation represented in the dengue virus’ four distinct strains makes vaccine development a complicated task. These strains, called serotypes, are each characterized by their own specific and unique properties. Scientists have already shown that an individual immune to any of the four strains increases his/her risk, not only of being infected by the other three strains, but also of developing severe life-threatening forms of this disease. This is why researchers need to develop a vaccine or treatment that targets all four serotypes.
Research teams from the Institut Pasteur, the CNRS, and Inserm, led by Félix Rey* and Hugues Bedouelle** (Institut Pasteur/CNRS), have, for the first time, succeeded in characterizing an antibody capable of neutralizing all four strains of the dengue virus in mice models. By using comparative analyses and high-resolution crystallography, Félix Rey’s team was able to visualize the way the antibody binds to the virus on the specific recognition sites of each strain.
The teams also showed that the antibody recognizes the surface protein of the virus with varying affinities and neutralization potencies according to the viral serotype (1, 2, 3 or 4), but that the neutralization mechanism is the same in each case. It involves irreversible disruption of the virus particle, rendering it harmless.
These results provide a novel molecular basis for understanding antibody neutralization of the four dengue viruses, and will undoubtedly help to design a safe, protective vaccine.
Financing for this work was provided by the Merck Serono chair, the French National Research Agency (ANR), the EMBO Long Term Fellowship, the French Ministry of Defense, and DENFRAME, the European program for dengue research.
