Excessive lung inflammation and airway epithelium damage are hallmarks of cystic fibrosis (CF) disease. It is unclear whether lung inflammation is related to an intrinsic defect in the immune response or to chronic infection. We aimed to determine whether TLR5-mediated response is defective in the CF airway epithelium. We used a newborn CF pig...

Background: Bacterial colonization in cystic fibrosis (CF) lungs has been directly associated to the loss of CFTR function, and/or secondarily linked to repetitive cycles of chronic inflammation/infection. We hypothesized that altered molecular properties of mucins could contribute to this process.Methods: Newborn CFTR+/+ and CFTR-/- were...

CD1d-restricted invariant Natural Killer T (iNKT) cells represent a unique class of T lymphocytes endowed with potent regulatory and effector immune functions. Although these functions are acquired during thymic ontogeny, the sequence of events that gives rise to discrete effector subsets remains unclear. Using an unbiased single-cell...

Excessive lung inflammation and airway epithelium damage are hallmarks of human inflammatory lung diseases, such as cystic fibrosis (CF). Enhancement of innate immunity provides protection against pathogens while reducing lung-damaging inflammation. However, the mechanisms underlying innate immunity-mediated protection in the lung remain...

Tentons un peu d'oublier l'année 2020, mais pas complètement . . . C'est une année qui nousaura conduits à des envies et des visions différentes. Les rencontres conviviales et bien-veillantes qui ponctuent nos journées chaque année au mois d'octobre depuis 2005 n'ontpu se dérouler comme prévues, mais nous étions tous présents pour les...
