As the total number of studies investigating GLP-1+ cell numbers and function in the context of intestinal inflammation is limited and results are conflicting,26,27,32, 33, 34 we quantified numbers of GLP-1 expressing cells in 4 different mouse models of ileal and colonic inflammation (TnfΔARE mice (ileitis), IL-10-/- mice, and adoptive T cell-transfer model (colitis) as well as Citrobacter rodentium-infection (colitis). This evidence concerns the gene GLP1R and colitis.
