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.
A new step towards using neural stem celles to repair the brain
A team from the Institut Pasteur associated with the CNRS has just identified a key molecule in the brain capable of attracting new neurons and guiding them towards areas that they could repair. This discovery, previewed on the site Nature Neuroscience (http://www.nature.com/neuro/), brings to the fore a molecule essential for the organization of neuronal circuits in adults. This introduces remarkable prospects for developing therapies for brain repair.
Paris, march 15, 2004
Until quite recently, neurobiologists believed that the brain and the spinal cord could not repair themselves. The discovery of stem cells within the adult brain itself has shattered this belief. Pierre-Marie Lledo’s team at the Institut Pasteur ("Perception and Memory" Unit, CNRS URA 2182) demonstrated that the adult brain manufactured true neurons capable of establishing new connections (Nat. Neurosci. 2003). This ability allows the adult brain to adapt itself to the changes occurring throughout life. It also offers the possibility for the brain to repair itself in case of injury or disease.
But how could neuronal precursors be led to the areas to be repaired? The researchers of Lledo’s team, in collaboration with Professor Melitta Schachner’s team from the University of Hamburg in Germany, have monitored these events in the olfactory bulb, the first cerebral relay of the response to smells, and one of the rare cerebral tissues where the recruitment of new neurons can be observed in adults. They showed that the presence of tenascin, a molecule secreted by the olfactory bulb, was sufficient to attract immature neurons to this region. There, the young cells became differentiated into true neurons. By having this molecule produced by another region of the brain, the researchers observed that the juvenile neurons were diverted from their location to join this target region. This molecule thus makes it possible to target the destination of neoneurons and could be a promising tool in cell therapy of the brain.
"This research enriches our knowledge in the area of cerebral mechanisms for organizing neural networks. It sheds new light on the repair functions of the central nervous system and could contribute to working out new treatment strategies aiming to divert newly formed neurons from their germ layer to regions to be repaired", Lledo commented.
