A project to strengthen National Ethics Committees in Francophone Africa
National Ethics Committees are key actors of the research and civil society world, responsible for assessing complex situations with regard to individual rights and the general interest both in the normal course as well as in times of crisis. When a clinical trial or any research involving individual is conducted, they are responsible for ensuring that research participants are protected and...

Meningococcal meningitis: stomach pain should be seen as a warning sign
Patients with meningococcal infection generally develop symptoms including a high temperature, vomiting and a stiff neck... but they might also just have a bad stomach ache. This can be so severe that they are sometimes wrongly operated for appendicitis. Teams from the Institut Pasteur and the Department of Pediatrics at Bicêtre Hospital (AP-HP) decided to investigate the question. And the...

Tiger mosquitoes: heightened surveillance in France, from May to November 2018
On Monday April 30, 2018, the French Ministry of Health announced that it was stepping up surveillance of the tiger mosquito, Aedes albopictus, which is now present in 42 French départements – twice as many as two years ago. But just how dangerous is this mosquito, vector of diseases such as dengue, chikungunya or zika?The tiger mosquito (see What is the "tiger mosquito" (Aedes albopictus)?) is...

Dengue: investigating antibodies to identify at-risk individuals
Using an original mathematical and statistical analysis method, a team of scientists from the Institut Pasteur partnered with researchers from the United States and Thailand to analyze a Thai cohort that has long been a focus of study for dengue specialists, and obtained new information that should help identify individuals at risk of infection. By modeling changes in antibody levels after...

Regulation of muscle stem cells in their niche: juggling external and internal cues
Little information is available on how stem cells acquire their special properties. A team from the Institut Pasteur has described a signalling pathway (Notch/COLV/CALCR) that proposes a new view on how muscle stem cells are retained in their local microenvironment (niche).Stem cells play critical roles during growth, regeneration and ageing. Although they possess special features that allow them...

From Molecular Biology to Stem Cells
May 1968… While students took to the streets of Paris, Jacques Monod and François Jacob were getting ready for what would prove to be a decisive turning point for the Institut Pasteur: the opening of a new department dedicated to molecular biology—in other words the study of the molecular mechanisms governing cell behavior. The venture, which included plans for purpose-built premises, had...

The Institut Pasteur de Nouvelle-Calédonie describes 12 new species of leptospires and pays tribute to Pasteurians
Environmental bacterial disease, leptospirosis causes nearly 1 million clinical infections per year. The Institut Pasteur de Nouvelle-Calédonie has been interested for many years with the disease whose incidence is particularly high in Oceania. Researchers from the Leptospirosis Research and Expertise Unit, led by Cyrille Goarant, recently isolated 12 new species of the genus Leptospira.In an...

Artificial intelligence speeds up high-resolution microscopy
Scientists from the Institut Pasteur have developed a method for increasing the spatio-temporal resolution in optical microscopy. This method, called ANNA-PALM, is based on recent developments in artificial intelligence and, more specifically, in much-talked-about deep learning. This article explores the method."Traditional optical microscopes can be used to distinguish structures in the range of...
