Yellow fever, the story of a re-emerging virus
With outbreaks in Angola in 2015 and Brazil in 2016, and cases detected in French Guiana in 2017 and even recently in Asia, where the virus had never previously been witnessed, yellow fever – a sometimes fatal mosquito-borne disease – has once again become a global public health problem. After major outbreaks between the 17th and 19th centuries, it never disappeared and has continued to be rife...

The web meets genomics: a DNA search engine for microbes
Microbes are the most common and diverse organisms on the planet. In recent years, researchers have accumulated data about them, particularly with respect to their genetic background. This avalanche of information - known as "Big Data" - is a fantastic source of new knowledge and medical progress. Researchers at the Institut Pasteur and EMBL’s European Bioinformatics Institute have combined their...

Insecticide resistance genes affect vector competence for West Nile virus
In a context of overuse of insecticides, which leads to the selection of resistant mosquitoes, it is already known that this resistance to insecticides affects interactions between mosquitoes and the pathogens they transmit. Researchers from the Institut Pasteur (Paris) and its partners prove that mechanisms of insecticide resistance, observed in Culex quinquefasciatus vector, impact the...

When the structure of Tunneling nanotubes (TNTs) challenges the very concept of cell
Cells in our bodies have the ability to speak with one another much like humans do. This communication allows organs in our bodies to work synchronously, which in turn, enables us to perform the remarkable range of tasks we meet on a daily basis. One of this mean of communication is ‘tunneling nanotubes’ or TNTs. In an article published in Nature Communications, researchers from the Institut...

A new breakthrough in limb development
Congenital limb defects are very common and occur in 1.5 in 1,000 births. Some are minor, such as a missing finger, while others are more serious, a missing limb for instance. Fundamental biology looks at the buds of developing limbs and how this development may be linked to defects. Limb position is fairly constant within a same species and yet relatively variable in vertebrates. In an article...

Alzheimer's disease
Alzheimer's disease is a neurodegenerative disease that mainly affects memory but also has an impact on other cognitive functions, for example those related to language, reasoning and learning. Alzheimer's disease generally leads to a loss of independence. It is one of the leading causes of disability and dependency in elderly people worldwide. There is currently no treatment for Alzheimer's...

Gene therapy durably reverses congenital deafness in mice
In collaboration with the universities of Miami, Columbia and San Francisco, scientists from the Institut Pasteur, Inserm, CNRS, Collège de France, Sorbonne University and the University of Clermont Auvergne have managed to restore hearing in an adult mouse model of DFNB9 deafness – a hearing disorder that represents one of the most frequent cases of congenital genetic deafness. Individuals with...
