A new optical microscopy approach opens the door to better observations in molecular biology
Researchers from the Institut Pasteur and CNRS have set up a new optical microscopy approach that combines two recent imaging techniques in order to visualize molecular assemblies without affecting their biological functions, at a resolution 10 times better than that of traditional microscopes. Using this approach, they were able to observe the AIDS virus and its capsids (containing the HIV...

A new hope in the fight against tuberculosis
Researchers from the Institut Pasteur and Inserm, in collaboration with researchers from the University of Pisa, have uncovered the key role played by specific proteins in the virulence of the mycobacterium responsible for tuberculosis, Mycobacterium tuberculosis. They were able to create an attenuated strain of the mycobacterium, which confers a better protection against tuberculosis than the...

DENFREE: flying towards the efficient control of dengue
Comfortably nested in the salivary glands of mosquitoes, the dengue virus moves around and infects everybody unlucky enough to be bitten. But on the wings of mosquitoes, it can’t possibly go very far and usually stays within a restricted community… unless it “changes vehicle” and travels further away thanks to the infected humans. Starting in January 2012, the Institut...

Europe’s united front against emerging viruses
The new PREDEMICS* project strives to improve current knowledge on certain emerging infectious diseases and develop effective treatment and prevention resources. The European Union will be financing this project to the tune of €11.7 million over a five year period. Coordinated by the Institut Pasteur, this collaborative program unites 17 European research and public health institutions. The...

Discovery of a new group of highly susceptible malaria mosquitoes in Africa
In the course of a large genetic study of malaria vector mosquitoes in Burkina Faso, West Africa, researchers at the Institut Pasteur, the French National Center for Scientific Research (CNRS) and their collaborators have discovered a new subspecies of the mosquito Anopheles gambiae, the world’s most important malaria vector. This new mosquito group, which may be an especially...

Identification of the 3D structure of chikungunya virus surface proteins
Researchers at the Institut Pasteur and CNRS, in collaboration with the Synchrotron SOLEIL, have solved the three-dimensional atomic structure of the glycoproteins that envelop the chikungunya virus. This discovery helps to understand how this protein complex is activated in order for the virus to invade target cells. Activation is a key stage in the viral life cycle and understanding its...

Male Infertility : Genetic Cause Identified
Scientists at the Institut Pasteur have identified a series of mutations in a gene that are associated with 4% of cases of, otherwise unexplained, severe male infertility. This discovery offers new opportunities not only in terms of an early diagnosis of male infertility associated with these mutations but also enables clinicians to provide counseling regarding the freezing of sperm or eggs to...

Tuberculosis: discovery of new genes involved in the parasitism of cells by the tubercle bacillus
A European-Asian collaboration of scientists, notably including CNRS, the Institut Pasteur in Paris, the Institut Pasteur Korea in Seoul (IP Korea/Equipe Avenir Inserm(1)) and the Université de Toulouse have identified ten virulence genes of the tubercle bacillus. The inactivation of these genes lessens the pathogenic effects of the bacillus. This discovery, published in the journal PLoS...

Antipain, antidepressant – an “all-in-one” molecule
Institut Pasteur scientists associated with the CNRS and a team from the ETAP-Applied Ethology neuropsychopharmacology research center based in Vandoeuvre-lès-Nancy have reported the analgesic and antidepressant effects of Opiorphin, a hormone messenger naturally secreted in humans that was discovered at the Institut Pasteur in 2006. The molecule has proved to be as potent as morphine in...
