概要 Polymeric immunoglobulin receptor (pIgR) plays an important role in mucosal immune systems. Secretory immunoglobulin A, composed of secretory component of pIgR and a dimeric form of immunoglobulin A, is secreted on mucosal surfaces and serves as a biological defense factor. pIgR gene expression is reportedly induced by activation of the transcription factor nuclear factor (NF)-kappa B. On the other hand, secretory leukocyte protease inhibitor (SLPI) is a glycoprotein that functions as a serine protease inhibitor. In alveolar epithelial cells, SLPI increases the level of I kappa B beta, which indicates that it is an inhibitor of NF-kappa B at the protein level. Taken together, SLPI may regulate plgR expression; however, the specific mechanism by which this occurs is unclear. Therefore, the aim of this study was to elucidatethe influence of SLPI on pIgR expression. SLPI and pIgR localized in goblet cells and ciliated epithelial cells of the gastrointestinal tract, respectively. No cells were detected in which SLPI and pIgR were co-expressed. In addition, recombinant human SLPI stimulation of an epithelial cell line (HT-29) decreased the pIgR expression. The pIgR expression was also h
