Butter feeding enhances TNF‐α production from macrophages and lymphocyte adherence in murine small intestinal microvessels

Abstract

T-lymphocyte adherence to microvessels of the small intestinal mucosa was significantly enhanced after butter ingestion. This enhancement is due to increase in expression levels of adhesion molecules of the intestinal mucosa, which is mediated by TNF-alpha from macrophages in the intestinal lamina propria.
