Difficulty staying awake may seem trivial, but it's the main symptom of one of the most severe sleep disorders: narcolepsy. In Montpellier, the Centre de référence des narcolepsies et hypersomnies rares (Inserm/University/CHU de Montpellier) headed by Yves Dauvilliers is conducting cutting-edge research into this disease.

Antibody fragments of EPCT112 bNAb (blue) discovered at the Institut Pasteur by Hugo Mouquet's team, here forming a complex with the HIV-1 envelope protein (Env) (shown in yellow and orange Some HIV-1 carriers who have received an early antiretroviral treatment during several years are able to control the virus for a long term after treatment interruption.

To understand the main determinants behind worldwide antibiotic resistance dynamics, scientists from the Institut Pasteur, Inserm, Université de Versailles Saint-Quentin-en-Yvelines and Université Paris-Saclay developed a statistical model based on a large-scale spatial-temporal analysis. Using the ATLAS antimicrobial resistance surveillance database, the model revealed significant differences in trends and associated factors depending on bacterial species and resistance to certain antibiotics.

In 2020, in the midst of the COVID-19 crisis, we spoke with Franck Zal, a doctor in marine biology from Sorbonne University and founder of the company Hemarina. At the time, HEMO2life - their flagship product created from the hemoglobin of the marine worm, the arenicole - was envisaged to improve the oxygenation of patients suffering from acute respiratory distress syndrome.

Cirrhosis is the final stage of fibrosis associated with chronic liver diseases. It affects 200,000 to 500,000 individuals in France and is responsible for 170,000 deaths per year in Europe. Adobe Stock Chronic liver diseases are characterized by persistent inflammation that contributes to their progression to more severe stages.

Publication of the CIRI in the journal Science Translational Medicine on March 15, 2023. Press realease of the INSERM on March 17, 2023. A large proportion of the population has developed immunity to SARS-CoV-2 following infection and/or vaccination. In addition, some infected patients benefit from a so-called "hybrid" immunity when they have been vaccinated after their infectious episode.

A large part of the population has developed immunity against SARS-CoV-2 following infection, vaccination - or both. In addition, some infected patients enjoy "hybrid” immunity when they are vaccinated following their infectious episode. Scientists from Inserm, CNRS, Université Claude-Bernard Lyon 1 and ENS de Lyon at the International Center for Research on Infectious Diseases (CIRI) seek to characterize the imprint left by SARS-CoV-2 exposure through vaccination or the combination of the two events on immune memory.

Inserm researchers at the Marseille Cancer Research Center (CRCM - AMU/Inserm/CNRS/IPC) and clinicians at the Paoli-Calmettes Institute (IPC) have identified a molecular test for personalized treatment of pancreatic cancer. This new strategy, based on the prediction of the sensitivity of each patient to the different chemotherapy protocols currently available, opens the way to personalized treatments for pancreatic cancer.

To combat allergic asthma, which affects millions of people worldwide, scientists from Inserm, CNRS and Université Toulouse III-Paul Sabatier at the Infinity laboratory , Institut Pasteur and French company NEOVACS are developing and testing a new vaccine. In their previous study, the teams had shown it to be effective in producing antibodies capable of neutralizing human immune proteins that play a key role in triggering allergic asthma, cytokines IL-4 and IL-13.

Obesity is a global public health problem with an increasing incidence. According to the WHO, since 1975, the number of obesity cases has almost tripled worldwide . Obesity is associated with numerous comorbidities and high mortality. It is estimated that this complex chronic disease increases the risk of cardiovascular disease (first cause of death in the world), diabetes, musculoskeletal disorders, many forms of cancer (endometrial, breast, ovarian, prostate, liver, gallbladder, kidney and colon.

Researchers from the University of Montpellier and Inserm at the Montpellier Neuroscience Institute have shown the preponderant role of the FLT3 receptor in chronic post-surgical pain. By inhibiting this receptor with therapeutic antibodies, the scientists could propose promising avenues for the prevention of chronic pain.

Pressing the gas pedal and lifting the brake at the same time is the innovative idea of Dr. Nicolas Manel, Inserm researcher and team leader at the Institut Curie (Immunity and Cancer Unit - Institut Curie, Inserm) to improve the response to immunotherapies. For several years, the researchers have identified a signaling pathway - STING - that is essential for accelerating the response to immunotherapies.
