Space is an extraordinary laboratory for medicine and medical research on Earth. That is why Inserm and the CNES have been working together for more than a year[1] to accelerate research progress to improve the health of all of us. The presence of Thomas Pesquet, French astronaut from the European Space Agency (ESA), on board the International Space Station (ISS) for 6 months gave rise to many experiments, the...
The 11th edition of National "Dys" Day will be held on Tuesday, October 10, 2017. Created by the Fédération Française des DYS, it mobilizes parents who are members of associations together with professionals from across France. The various learning disabilities that begin with "dys", and which are now better understood by the general public, affect around 6 million people in France [1](METTRE CHIFFRE). An event is held in Paris...
Adenomatous polyposis coli (APC) is a gene whose mutations are associated with a rare, hereditary form of colorectal cancer known as familial adenomatous polyposis. Research led by scientists at the Institut Pasteur and Inserm have recently demonstrated that mutations to this gene do not only lead to the emergence of colon polyps; they also harm the immune system, leaving it unable to tackle inflammation of the colonic mucosa. This...
On Monday, October 2, three Americans, Jeffrey C. Hall, Michael Rosbash and Michael W. Young, were awarded the 2017 Nobel Prize in Physiology or Medicine for their research on the control of circadian rhythms.
An epidemiological study carried out by Inserm on families from the EDEN cohort (500 boys born between 2003 and 2006 and their mothers) shows that exposure during pregnancy to certain phenols and phthalates is associated with behavioral problems in boys between 3 and 5 years of age. The most worrying compounds in this respect are bisphenol A, triclosan and dibutyl phthalate (DBP).
Associated with an aging population and the development of metabolic syndrome, atherosclerosis is a leading cause of death worldwide. Researchers from Inserm Unit 970, the "Paris Cardiovascular Research Center" (Inserm/Université Paris Descartes), have succeeded in revealing the mechanisms underlying the formation of atherosclerotic plaques. In particular, they have discovered the protective role of autophagy, a mechanism for cleaning and recycling cell components, in the cells that line the inner...
A team of researchers from CEA, Inserm, and the Paris-Sud and Paris Diderot universities has shown that exposure to low doses of irradiation (0.02 Gy) leads of a loss of hematopoietic stem cell[1] (HSC) function. The team has also shown that irradiation at this low dose facilitates efficient bone marrow transplantation without myeloablation[2]. These results, published in Cell Reports on September 26, 2017, show both the positive and negative...
Between 2010 and 2012, 256 women died in France from causes linked to pregnancy, labor, or following childbirth, amounting to 85 such cases a year. Although inequalities remain, improvements have been observed in the provision of labor care, with the death rate from hemorrhage halving. These epidemiological results have been made public by the triennial report of the Confidential Inquiry into Maternal Deaths (Enquête Confidentielle sur les Morts Maternelles, ENCMM) in...
The ANRS consortium "Humanized Mouse Models for Viral Hepatitis"1, made up of 6 teams of researchers, has developed a mouse model for studying the interaction between the immune system and the liver following infection by the hepatitis B virus. This research, coordinated by Dr. Hélène Strick-Marchand (Inserm joint unit 1223, "Physiopathology of the Immune System", Institut Pasteur), responds to a real lack of animal models for studying this disease...
Scientists from the Institut Pasteur, Inserm, the CNRS, Collège de France, University Pierre et Marie Curie, and University Clermont Auvergne*, have recently restored hearing and balance in a mouse model of Usher syndrome type 1G (USH1G) characterized by profound congenital deafness and vestibular disorders caused by severe dysmorphogenesis of the mechanoelectrical transduction apparatus of the inner ear’s sensory cells. By locally injecting the USH1G gene, critical for the formation...
