| Outline of Final Research Achievements |
Diet-induced obesity induces chronic inflammation. At postplandial period, various external antigens other than dietary lipids get into lymph ducts and evoke immune responses. In this study, we evaluated factors in lymph ducts by using lymph-cannulated rats especially at a postplandial period. At several hours after administration of dietary lipids, there was a significant increase of interleukin-6(IL-6) and glucagon-like peptide-1 in the lymph. Gene expression analysis in food-deprived or fed rats indicated that an accumulation of IL-6 producing cells in the intestinal mucosa accompanied by lipid absorption.
