Localization of Free and Bound Secretory Component in Human Intestinal Epithelial Cells

Antibody reagents were made specific for each of the two forms of human SC, FSC and BSC, which is an integral part of the sIgA molecule. With the fluorescent antibody method the cytological and histological localization of FSC, BSC, and alpha-chains has been studied in various human mucous membranes. SC was present in columnar epithelial cells of the intestines and in the cells of serous acini ...

Neuroendocrinimmune modulation of secretory component production by rat lacrimal, salivary, and intestinal epithelial cells.

PURPOSE To evaluate the kinetics, receptor specificity, molecular basis, and site selectivity of the endocrine and neural regulation of secretory component (SC) synthesis by rat lacrimal gland acinar cells. METHODS Acinar cells from the rat lacrimal and submandibular glands, as well as epithelial cells (IEC-6) from the rat small intestine, were cultured in supplemented, serum-free media and t...

Effect of hyperoxia on the intestinal IgA secretory component in neonatal rats and on intestinal epithelial cells in vitro.

Oxygen therapy is essential for the treatment of some neonatal critical care conditions but its extrapulmonary effects have not been adequately investigated. We therefore studied the effects of various oxygen concentrations on intestinal epithelial cell function. In order to assess the effects of hyperoxia on the intestinal immunological barrier, we studied two physiological changes in neonatal...

Cloning and secretory expression of VP2 gene of infectious bursal disease virus in eukaryotic cells

VP2 gene coding region of a vaccinal strain (D78) of infectious bursal disease virus (IBDV) was clonedin a eukaryotic expression vector, pSec Tag2A. The gene was placed downstream of Ig κ chain leadersequence, under the control of human cytomegalovirus (hCMV) immediate early enhancer and promoter. Theconstruct pSec Tag2A-VP2 was transfected in COS-7 cell line and the expression and secretion of...

Transgenic Expression of Human Lysophosphatidic Acid Receptor LPA2 in Mouse Intestinal Epithelial Cells Induces Intestinal Dysplasia

Lysophosphatidic acid (LPA) acts on LPA2 receptor to mediate multiple pathological effects that are associated with tumorigenesis. The absence of LPA2 attenuates tumor progression in rodent models of colorectal cancer, but whether overexpression of LPA2 alone can lead to malignant transformation in the intestinal tract has not been studied. In this study, we expressed human LPA2 in intestinal e...
