Polymeric Immunoglobulin Receptor
Introduction Genes of interest can be targeted specifically to respiratory epithelial cells in intact animals with high efficiency by exploiting the receptor-mediated endocytosis of the polymeric immunoglobulin receptor. A DNA carrier, consisting of the Fab portion of polyclonal antibodies raised against rat secretory component covalently linked to poly-L-lysine, was used to introduce plasmids ...
متن کاملPolymeric immunoglobulin receptor.
The surface of mucosal sites, such as the intestinal tract, are covered by epithelial cells. To protect the intestinal environment from invading pathogens and maintain homeostasis, the human body developed an exquisite acquired immune system, referred to as the mucosal immune system, in which epithelial cells and lymphocytes function cooperatively. The main player in this immune system is the p...
متن کاملThe basolateral sorting signal of the polymeric immunoglobulin receptor contains two functional domains.
Basolateral sorting of the polymeric immunoglobulin receptor (pIgR) expressed in Madin-Darby canine kidney (MDCK) cells is mediated by a 17-residue sorting signal that resides in the cytoplasmic domain. We have recently analyzed the sequence requirements of the signal by alanine scanning mutagenesis. We found that basolateral sorting is mediated primarily by three amino acids: H656, R657 and V6...
متن کاملthe effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
15 صفحه اولFunctional expression of the polymeric immunoglobulin receptor from cloned cDNA in fibroblasts
The polymeric immunoglobulin receptor, a transmembrane protein, is made by a variety of polarized epithelial cells. After synthesis, the receptor is sent to the basolateral surface where it binds polymeric IgA and IgM. The receptor-ligand complex is endocytosed, transported across the cell in vesicles, and re-exocytosed at the apical surface. At some point the receptor is proteolytically cleave...
