Abstract
Le système digestif est colonisé dès la naissance par une population bactérienne, le microbiote, qui influence le développement du système immunitaire. Des modifications dans sa composition sont associées à des pathologies comme l'obésité et les maladies inflammatoires chroniques de l'intestin. Outre les antibiotiques, des facteurs environnementaux comme le tabagisme semblent aussi avoir une influence sur la composition de la flore intestinale, pouvant en partie expliquer la prise de poids à l'arrêt du tabac avec une modification de la composition du microbiote proche de celle observée chez des personnes obèses (profil microbiotique montrant des capacités accrues d'extraction calorique des aliments ingérés). Ces découvertes permettent d'imaginer de nouvelles approches diagnostiques et thérapeutiques via la régulation de ce microbiome.
The digestive tract is colonized from birth by a bacterial population called the microbiota which influences the development of the immune system. Modifications in its composition are associated with problems such as obesity or inflammatory bowel diseases. Antibiotics are known to influence the intestinal microbiota but other environmental factors such as cigarette smoking also seem to have an impact on its composition. This influence might partly explain weight gain which is observed after smoking cessation. Indeed there is a modification of the gut microbiota which becomes similar to that of obese people with a microbiotical profile which is more efficient to extract calories from ingested food. These new findings open new fields of diagnostic and therapeutic approaches through the regulation of the microbiota.
