Abstract
Claire BillereyLarmonier Jennifer K Uno Nicolas Larmonier Anna J Midura Barbara Timmermann Fayez K Ghishan Pawel R Kiela Protective effects of dietary curcumin in mouse model of chemically induced colitis are strain dependent Inflammatory Bowel Diseases Volume 14 Issue 6 1 June 2008 Pages 780–793 https//doiorg/101002/ibd20348Curcumin diferulolylmethane has been shown to have a protective role in mouse models of inflammatory bowel diseases IBD and to reduce the relapse rate in human ulcerative colitis UC thus making it a potentially viable supportive treatment option Trinitrobenzene sulfonic acid TNBS colitis in NKTdeficient SJL/J mice has been described as Th1mediated inflammation whereas BALB/c mice are believed to exhibit a mixed Th1/Th2 responseIn the BALB/c mice curcumin significantly increased survival prevented weight loss and normalized disease activity In the SJL/J mice curcumin demonstrated no protective effects Genomewide microarray analysis of colonic gene expression was employed to define the differential effect of curcumin in these 2 strains This analysis not only confirmed the disparate responses of the 2 strains to curcumin but also indicated different responses to TNBS Curcumin inhibited proliferation of splenocytes from naive BALB/c mice but not SJL/J mice when nonspecifically stimulated in vitro with concanavalin A ConA Proliferation of CD4+ splenocytes was inhibited in both strains albeit with about a 2fold higher IC50 in SJL/J mice Secretion of IL4 and IL5 by CD4+ lymphocytes of BALB/c mice but not SJL/J mice was significantly augmented by ConA and reduced to control levels by curcuminThe efficacy of dietary curcumin in TNBS colitis varies in BALB/c and SJL/J mouse strains Although the exact mechanism underlying these differences is unclear the results suggest that the therapeutic value of dietary curcumin may differ depending on the nature of immune dysregulation in IBD
