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.
Malaria: a beneficial genetic mutation in South-East Asia
A large-scale evolutionary and epidemiological genetic study carried out over an eight-year period in Thailand has enabled Institut Pasteur and CNRS researchers to demonstrate that a mutation that is particularly widespread in some South-East Asian populations offers a higher level of resistance to malaria. This research, published in the December 11 issue of the journal Science, also reveals that this beneficial mutation emerged 1500 years ago and significantly boosted the survival rate of these populations.
Paris, december 11, 2009
Researchers have recently identified a genetic mutation that offers resistance to malaria in South-East Asia. Under the direction of Anavaj Sakuntabhai, from the Institut Pasteur's Viral Pathogenesis Unit, and Lluis Quintana-Murci, from the Human Evolutionary Genetics Unit (Institut Pasteur / CNRS), and in cooperation with Mahidol University in Thailand, the researchers conducted a large-scale study over an eight-year period on more than 3500 people in Thailand, using evolutionary and epidemiological genetics approaches. The results of this work demonstrated an increased survival rate for carriers of this protective mutation, and its association with a significant reduction in the number of parasites in the blood.
The researchers particularly demonstrated a correlation between the mutation and a lower parasite load of Plasmodium vivax, the primary malaria agent in South-East Asia, responsible for half of all malaria cases in the region. In addition to typical malaria symptoms, this parasite is implicated in causing very low birth weight, a risk factor for all cause perinatal mortality; it therefore has alarming repercussions for the health and survival of young children and babies.
The mutation identified by researchers as having a protective effect, named G6PD-Mahidol487A, affects the gene of the G6PD enzyme. A deficiency in this enzyme has been known for a long time to cause favism, following the ingestion of fava beans and other “oxidative” foods ", with subsequent pathologies of varying degrees of severity, including jaundice and anemia. The G6PD-Mahidol487A mutation is particularly frequent in South-East Asia, where it is carried by 18 to 25% of the population. In revealing its protective effect against Plasmodium vivax, the study therefore explains why this mutation, which has the above-mentioned deleterious consequences, has been able to reach such high levels in this region of the world. Previous research conducted in Africa demonstrated that another mutation affecting the same gene offered resistance to Plasmodium falciparum, the main malaria agent on that continent. But the current study is the first to show a direct link between a mutation affecting the G6PD gene and malaria caused by Plasmodium vivax.
Finally, the study enabled researchers to date the emergence of the G6PD-Mahidol487A beneficial mutation in the human genome. It first occurred 1500 years ago in South-East Asia, coinciding with the expansion of rice cultivation, which required extensive deforestation and therefore brought humans and mosquitoes, vectors of malaria, into closer contact. Given this increased "infectious pressure" due to a greater exposure to mosquitoes, those who carried the G6PD-Mahidol487A mutation had an advantage, and more were able to survive.
Positively selected G6PD-Mahidol mutation reduces Plasmodium vivax density in South-East Asians, Science, December 11, 2009.
