Proteomic Analysis of Crohn's Disease Macrophages in Response or Not to AIEC

The macrophages characterization will be realized at a basal state and in response or not to AIEC. Investigator aimed to 1) better understand the differences between macrophages of CD patients, UC patients and healthy volunteers but also the impact of AIEC infection on these macrophages to provide key informations to detect and characterize the defect of these macrophages; 2) highlight one or several protein in CD macrophages that could represent, in a long term, a potential therapeutic target of CD.
