The alteration of enterochromaffin cell, mast cell, and lamina propria T lymphocyte numbers in irritable bowel syndrome and its relationship with psychological factors

Abstract

Enterochromaffin cells, mast cells, and lamina propria T lymphocytes significantly increase in PI IBS, whereas only mast cells significantly increase in non-PI IBS-D. Such histopathological changes do not seem to be directly associated with psychological factors.
