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.
Researchers at the Institut Pasteur and CNRS have just identified a new source of neurons in the adult brain. Their study, published in the Journal of Neuroscience, provides proof of the brain's intrinsic capacity to self-repair. This work also opens unexpected perspectives for the development of therapies, particularly the treatment of neurodegenerative pathologies, such as Parkinson's disease or Huntington's chorea.

Une nouvelle zone du cerveau adulte au sein de laquelle naissent les néo-neurones.Neurobiologists had always thought that the brain and spinal cord were unable to repair themselves in the event of lesion or disease, but the discovery in 2003 of stem cells capable of generating neurons to the olfactory bulb, by Pierre-Marie Lledo and his team at the Institut Pasteur (Perception and Memory Unit, CNRS URA 21182) completely transformed this fundamental neurobiological principle. Researchers demonstrated that certain non-neuronal cells, known as glial cells, could be transformed into neurons, which in turn were capable of integrating into the existing circuits. The following year, the same research unit identified a molecule responsible for attracting these newborn neurons from their production zone to the olfactory bulb.
Since then, Pierre-Marie Lledo and his team are currently bringing new hope for strategic therapies aimed at repairing the brain. Today, in collaboration with the Molecular Virology and Vectorology Unit, led at the Institut Pasteur by Pierre Charneau, researchers are proving that these glial stem cells capable of being transformed into neurons are located not only in the classical zone already identified in 2003, but also along the whole length of a migratory tunnel in which newborn neurons navigate, as well as in the core of the target circuit: the olfactory bulb.
Researchers have been able to observe and directly prove this phenomenon thanks to the development of a viral vector capable of specifically targeting glial cells and rendering them fluorescent. After injecting this vector into a known neurogenic region, and then into new areas, they observed that several regions of the brain became fluorescent, and therefore had the unique capacity to produce neurons.
The team also discovered that the absence of olfactory stimulation, as a result of a lesion in the olfactory sensory organ, intensified the transformation of glial cells into neurons. The formation of newly-generated neurons in the adult brain triggered in this way proves that the brain has intrinsic self-repairing properties.
“These studies shed new light on the repair systems of the central nervous system,” emphasized Pierre-Marie Lledo. “By diverting newly-formed neurons away from their germinal zone to the damaged areas, we can hope to contribute to the development of new therapeutic strategies for neurodegenerative pathologies such as Huntington’s chorea or Parkinson’s disease.”
