Cannabis: Insomnia Twice as Common Among Students Who Use It Every Day
In a new study, researchers from Inserm, Université de Bordeaux and Bordeaux University Hospital focused on cannabis use by students – with the knowledge that its consumption among 18-25-year-olds in France is particularly high – and tried to measure its effects on sleep.

New data of efficacy of a Meningococcal B Vaccine and a Preventive Antibiotic in Reducing the Risk of Sexually Transmitted Bacterial Infections and proven efficacy of the MVA-BN Vaccine Against Mpox
Une étude menée par une équipe de recherche de l’AP-HP, Université Paris Cité, l’Inserm, Sorbonne Université en collaboration avec AIDES et Coalition PLUS démontre à la fois l’efficacité d’un vaccin contre le méningocoque B dans la réduction du risque d’infection par le gonocoque et celle de l’utilisation de l’antibiotique doxycycline comme traitement préventif contre les infections sexuellement transmissibles, lorsqu’il est pris dans les 72 h suivant un rapport sexuel.

A blood factor involved in depression
Scientists from the Institut Pasteur, CNRS and Inserm have discovered that administration of the GDF11 protein, which is known to regenerate murine neural stem cells, improves cognitive abilities and reduces the depressive state in aged mice. They also demonstrated the mechanism of action of this protein in different mouse models. The scientists then investigated these results further in relation to depression, and showed that in humans, the levels of GDF11 are inversely related to depressive episodes.

Obesity and Overweight: Almost One in Two French People Affected. Current Situation, Prevention and Therapeutic Solutions
Obesity is a global public health problem whose incidence continues to increase. According to the World Health Organization (WHO), the number of cases worldwide has almost tripled since 1975.

Who are the first ancestors of present-day fish?
What is the origin of the ancestors of present-day fish? What species evolved from them? A 50-year-old scientific controversy revolved around the question of which group, the “bony-tongues” or the “eels”, was the oldest. A study by INRAE, the CNRS, the Pasteur Institute, Inserm and the Muséum National d’Histoire Naturelle, has just put an end to the debate by showing through genomic analysis that these fishes are in fact one and the same group, given the rather peculiar name of “Eloposteoglossocephala”.

Cystic Fibrosis: A New Therapeutic Avenue Thanks to Research Into an Edible Mushroom
Une molécule issue d’un champignon comestible pourrait ouvrir des perspectives thérapeutiques pour des patients atteints de mucoviscidose, la maladie génétique rare la plus fréquente. Une équipe de recherche dirigée par Fabrice Lejeune, chercheur Inserm au sein du laboratoire Cancer heterogeneity, plasticity and resistance to Therapies (Inserm/ CNRS/ Université de Lille/Institut Pasteur de Lille/CHU Lille) a testé les effets de la 2,6-diaminopurine (DAP), l’un des principes actifs contenus dans le champignon Lepista flaccida, dans différents modèles expérimentaux de la maladie. Les scientifiques ont ainsi montré que cette molécule pourrait avoir un intérêt thérapeutique pour les patients atteints de mucoviscidose liée à une mutation particulière, dite mutation non-sens.

Discovery of a circovirus involved in human hepatitis
Scientists from the Institut Pasteur, Necker-Enfants Malades Hospital (AP-HP), Inserm in the Imagine Institute, Université Paris Cité and the Alfort National Veterinary School (EnvA) have identified a previously unknown species of circovirus, provisionally named human circovirus 1 (HCirV-1). Circoviruses are a family of small, highly resistant DNA viruses that were initially identified in 1974 in various animal species, where they can cause respiratory, renal, dermatological and reproductive problems. HCirV-1 is a novel virus that is distant from known animal circoviruses. It was shown to be implicated in damage to the liver of a patient undergoing immunosuppressive treatment.

Dengue and Zika Viruses: Towards a Better Understanding of the Mechanisms of Transmission
Aedes mosquitoes are the principal vectors of dengue and other arboviruses, including Zika, for which no vaccines or antiviral treatments currently exist. Understanding the factors that influence the transmission of arboviruses from mosquitoes to humans is therefore a priority because it could guide the implementation of public health measures that could limit or even prevent epidemics. In a new study, a team of researchers from Inserm, CNRS and Université de Strasbourg at the Institute of Molecular and Cellular Biology, in collaboration with the Federal University of Minas Gerais in Brazil, described the virome (the totality of the viruses) present in 800 mosquitoes collected in six countries across four continents. The scientists show that out of the 12 viruses identified, two of them do not infect humans but increase the potential for transmission of dengue and Zika. The mechanism involved reveals the existence of a new cellular factor hijacked by arboviruses in mosquitoes.

Reproductive Life Factors and Hormone Therapy May Affect Women’s Risk of Parkinson’s Disease
Exposure to the hormones involved in female reproductive life is one of the avenues explored at the Epidemiology and Population Health Research Center (CESP) by a research team from Inserm, Université Paris-Saclay, Université de Versailles Saint-Quentin-en-Yvelines with Institut Gustave Roussy, which compared the reproductive characteristics of nearly 1,200 women with Parkinson’s disease with those of other women from the E3N cohort . Their findings show that age at first menstrual period, number of pregnancies, type of menopause and a molecule used to improve fertility are associated with a higher risk of developing the disease.
