American researchers at the Cincinnati Children’s Hospital Medical Center and French researchers from Inserm (joint research Unit 913 “Neuropathies of Enteric Nervous System and Digestive Diseases”, Nantes) have succeeded in generating a functional human intestine using pluripotent human stem cells. This significant breakthrough was achieved by cultivating human intestinal tissue using nerve cells. Details of their work are published online on 21 November 2016 in Nature Medicine.
A national trial on membranous glomerulonephritis in 80 patients was coordinated by Prof. Pierre Ronco, of the Department of Nephrology and Dialysis at Tenon Hospital AP-HP, of the Inserm Unit “Rare and common kidney diseases, matrix remodelling and tissue repair” [1] and Pierre and Marie Curie University, and by Dr Karine Dahan, of the Nephrology Day Hospital at Tenon Hospital AP-HP. This serious autoimmune disease is the most common...
Dr. Federico MINGOZZI, Team Leader of the Immunology and Liver Gene Transfer unit at Généthon, (Inserm U951/UPMC), France, has demonstrated the long-term efficacy of an optimized AAV-UGT1A1 vector for the correction of Crigler-Najjar syndrome (CN) in two different animal models of the disease. This work, published in July 20, 2016 in Molecular Therapy Methods and Clinical Development was supported by the AFM-Telethon.
Des chercheurs de l'Inserm et de l'Université Pierre et Marie Curie du Centre de Recherche des Cordeliers, en collaboration avec des chercheurs de l'institut Karolinska en Suède, ont décrit le mécanisme par lequel le facteur GPS2 réprime la survenue du diabète de type 2 chez les personnes obèses. Ces travaux, publiés dans la revue Nature Medicine, mettent en lumière l'importance de l'épigénome dans l'apparition de la maladie.
Modifications of the gut microbiota in chronic inflammatory bowel disease (Crohn’s disease and ulcerative colitis) are both the cause and consequence of these internal disorders. This has been shown a team of French researchers from Inserm, INRA[1], UPMC and AP-HP, who describe these mechanisms and propose new therapeutic approaches. Their work is published in Nature Medicine on 9 May 2016.
Heart failure affects over one million people in France. Although the blood system is the first to have been explored for the purpose of improving heart function, a study by Inserm has revealed the potential of a secondary system that had previously received scant attention. The researchers[1] analysed the heart lymphatic system in an animal model. They showed that this system was highly impaired following a myocardial infarction. Using...
The intestinal microbiota is necessary to ensure optimum postnatal growth and contributes to determining the size of adult individuals, notably in the event of undernutrition. The key element in this relationship is Insulin-like Growth Factor-1 (IGF-1), whose production and activity are in part controlled by the microbiota. This has recently been demonstrated in mice by scientists at the Institut de Génomique Fonctionnelle de Lyon (CNRS/ENS Lyon/Université Claude Bernard...
A team of researchers (AP-HP, AVENIR-ATIP–Inserm team[1], INRA[2], UPMC[3]) led by Dr Harry Sokol, from the Department of Gastroenterology and Nutrition, Saint Antoine Hospital, AP-HP, used a high-throughput sequencing method to show an imbalance in the fungal microbiota of patients with inflammatory bowel disease (IBD), with variations according to the type of disease and topography of lesions. The fungal component (made up of moulds and yeasts) of the microbiota...
A study conducted on mice by researchers at Inserm and UPMC (Pierre and Marie Curie University) offers a new type of immunotherapy approach for treating Alzheimer's disease. This involves amplifying a specific population of T lymphocytes that regulate immune and neuroinflammatory mechanisms that develop during the disease. These results are published in the journal Brain.
12 patients suffering from severe erectile dysfunction following prostate cancer received a transplant of stem cells into the penis. After six months, significant improvements in the quality of sexual intercourse, erection, penile rigidity and quality of orgasm were reported by the patients, according to a study by Inserm. This clinical trial was conducted under the direction of Professor René Yiou at the Department of Urology, Henri Mondor University Hospital,...
