GLP-1R immunostaining in colon.
GLP-1R (Acris antibody, A,B) and Neurofilaments (C, D) positive nerve fibres in mucosal sigmoid colon biopsy specimens from top—control and middle–IBD, magnification x20. Bar charts showing an overall increase in expression of neuronal fibres expressing GLP-1R in the IBD group (n = 4) by image analysis of GLP-1R (E) and NF (F) in colonic biopsies (mean ± SEM, Mann Whitney U test).
