Fig. 3. AMP peptide reduces colonic shortening in T-cell transfer model of IBD.
RAG-1−/− mice were reconstituted with splenic CD45RBhigh CD4+ T cells (4 X 105 cells, 95% pure). Treatment with AMP peptide (25 mg peptide/kg, s.c.) or vehicle began when the animals lost 5% body weight, or exhibited diarrhea or hematochezia. Whole colons were harvested and lengths were measured on days 10 or 21 (n=20; * P=0.032, ** P=0.00005).
