Qu’est-ce que le projet Milieu Intérieur ?

Le projet Milieu Intérieur est l’un des lauréats de la première vague d’appel d’offre “Laboratoire d’Excellence”. Le projet Milieu Intérieur réunit l’expertise multidisciplinaire de chercheurs dans les domaines de l’immunologie, l’infectiologie, la microbiologie, la virologie, la génétique humaine, la biologie évolutive et systémique. Le projet prend son nom du concept développé au XIXè siècle par le physiologiste Claude Bernard selon lequel le « milieu intérieur » régit les principes mêmes de la vie et se nourrit de la longue tradition de recherche translationnelle initiée par Louis Pasteur. Ce projet est coordonné par le Prof Matthew Albert et le Dr Lluis Quintana-Murci.

Présentation

La prédisposition aux infections, la sévérité des maladies et la réponse aux médicaments ainsi qu’aux vaccins sont très variables d’un individu à l’autre. Bien que la question de la variabilité dans les populations continue à être un point central de la recherche scientifique, les pratiques médicales et les politiques de santé publique reposent en général sur un modèle unique de prise en charge des maladies et de développement des médicaments. En raison de la complexité des réponses immunitaires dans l’individu et dans la population, jusqu’à présent, il n’a pas été possible de définir les paramètres – génétiques ou environnementaux – qui définissent un système immunitaire sain et sa variabilité naturelle. Le Consortium Milieu Intérieur porte un regard sans précédent sur le système immunitaire humain. Le Consortium Milieu Intérieur intègre la technologie de pointe de plusieurs disciplines scientifiques, parmi lesquelles l’immunologie, la génomique, la biologie moléculaire et la bioinformatique, afin d’établir les paramètres qui caractérisent le système immunitaire des individus en bonne santé. Une analyse approfondie de cette recherche ouvrira la voie à la médecine personnalisée: l’adaptation de la bonne stratégie thérapeutique pour la bonne personne au bon moment.

Title – Integrating genetic and microbiome risk profiles for disease prediction using multivariate analysis
Person in charge – Petar Scepanovic
Affiliation – Roche Basel, Switzerland
Project with pRED, Roche aims to test the hypothesis that the host genetics and microbiome act in an independent manner. Through the use of polygenic risk scores and microbiome dysbiosis index, we aim to derive prediction models for various diseases that could be of relevance for healthy individuals.

Title – Establishing a baseline gut microbiota index of healthy vounteers
Person in charge – Rafi Ahmad
Affiliation – Inland Norway University
Baseline Gut Microbiota Index” project aims to facilitate the understanding of immune responses in relation to physiology, genetics, and environment from a microbiome perspective. This would enable a better understanding of variables regulating and/or influencing the immune system, which aids in understanding the role of microbiota in immune responses along with identifying therapeutic targets enabling personalised treatment

Title – Exploring Pathogenic Mechanisms of Chronic Inflammatory Diseases : unresolved issues in IL-23/IL-17 biology
Person in charge – Ikram Mezgiche, Elisabetta Bianchi, Lars Rogge
Affiliation – Institut Pasteur
Our project aims to improve our understanding of the so-called “IL-23/IL-17 axis” in the pathophysiology of axial spondyloarthritis, psoriatic arthritis, and psoriasis. We will address the effects of IL-23 on distinct cell populations from patients and how is expression of the IL-23 receptor regulated.
