IL10 and inflammatory bowel disease: We therefore decided to focus on genes differentially expressed when comparing inoculated Il10-/- mice (i.e. CIF, EF, and EF·CIF) with Il10-/- mice not receiving an inoculation, in order to better understand interactions or relationships between genes which may be leading to the increased inflammation observed in the inoculated mice (first hypothesis), and to compare these changes with those previously observed in human IBD (second hypothesis).
