Abstract
Stromal cells, such as myofibroblasts and fibroblasts, represent a significant fraction of MHC class II-positive cells in the normal human colonic lamina propria, suggesting they may play an important role in CD4+ T cell regulation in a tolerogenic environment. The aim of this study was to examine whether human colonic myofibroblasts (CMFs) phenotypically and functionally resemble conventional antigen-presenting cells (APCs). Our results support the hypothesis that intestinal myofibroblasts are a novel, nonprofessional APC phenotype important in modulating mucosal T cell responses. Given their strategic location, we propose that intestinal myofibroblasts play a critical role in mediating tolerance to luminal antigens.
