Human intestinal epithelial cell inflammatory responses to amebic infection were inhibited by the intraluminal administration of an antisense oligonucleotide to the human p65 subunit of nuclear factor kappaB , and the role of neutrophils in tissue damage observed with amebiasis was studied by depleting neutrophils from SCID-HU-INT mice .
 ( cell type: neutrophils, None) , ( cell type: intestinal epithelial cell, None) , ( protein: nuclear factor kappaB, None) , ( protein: human p65 subunit, None)
