Des biologistes, quelques briques LEGO®, une créativité étirée à l’infini

Une équipe de chercheurs de l’Inserm, au sein de l’Institut de recherche sur le cancer et le vieillissement (Inserm/CNRS/Université Côte d’Azur), a eu l’idée d’utiliser des briques de LEGO® pour concevoir un nouveau système d’étirement permettant de simuler certaines contraintes mécaniques que subissent les cellules au sein de l’organisme.

A New Blood Component Revealed

Does the blood we thought to know so well contain elements that had been undetectable until now? The answer is yes, according to a team of researchers which has revealed the presence of whole functional mitochondria in the blood circulation. These organelles that are responsible for cellular respiration had hitherto only been found outside cells in very specific cases.

Meningeal Lymphatic Network: A New Avenue in the Treatment of Brain Tumors

Glioblastomas are the most common type of brain tumor, and their prognosis is often highly unfavorable. A collaborative study by Jean-Léon Thomas, Inserm researcher at the Brain & Spine Institute (Inserm/CNRS/Sorbonne Université) and Pitié-Salpêtrière Hospital AP-HP, and Akiko Iwasaki (Department of Immunology, Yale University School of Medicine, USA), has revealed the beneficial role played by the meningeal lymphatic vascular network in treating these tumors – in the short and longer term.

B Cells: New Allies in Sarcoma Immunotherapy?

An international team led by Wolf Hervé Fridman with researchers from Inserm, Sorbonne Université and Université de Paris at the Cordeliers Research Center, in collaboration with the French League against cancer and Institut Bergonié, has shown that B cells also play a major role in predicting of patient’s response to immunotherapy. It was previously thought only T cells could be used in this way.

Metastasis: When Cancer Cells Hitch a Ride Through the Bloodstream

Circulating tumor cells use the blood and lymphatic networks to disseminate within the body, forming metastases distant from the primary tumor. Inserm researcher Jacky Goetz and his Tumor Biomechanics team at the Molecular ImmunoRheumatology laboratory (Inserm/Université de Strasbourg) have helped to show that the flow properties of these biological fluids have a huge influence on the risk of developing metastases.

Towards a Drug to Combat a Severe Intestinal Disease in Children, Immunocompromised Patients

Researchers have recently discovered a new candidate drug to control cryptosporidiosis, a severe intestinal disease in children, immunocompromised patients, and young ruminants. Beyond this disease, their research represents an opportunity to discover new therapeutic avenues for related infections, such as toxoplasmosis and malaria.

A Vaccine to Overcome Immunotherapy Resistance

Researchers have shown that a commercially-available vaccine can overcome resistance to immunotherapy. Their study, published in Science Translational Medicine, shows that not only can gastroenteritis vaccines induce the immunogenic death of cancer cells in vitro, but also that combining them with immunotherapy triggers a potent anti-tumor immune response in vivo – where immunotherapy alone had failed.

Pediatric Cancers: Why Some Forms of Leukemia Only Affect Children

Acute myeloid leukemia (AML) mainly affects children, with the prognosis often being poor despite several decades of research into more effective treatments. A new study explains why some forms of leukemia develop in very young children.
