Receptor mediated transcytosis
WebbReceptor-mediated endocytosis (RME), also called clathrin-mediated endocytosis, is a process by which cells absorb metabolites, hormones, proteins – and in some cases … Transcytosis can be receptor-mediated and consists of three steps: 1) receptor-mediated endocytosis of the molecule on one side of the cell, e.g. the luminal side; 2) movement of the molecule through the intracellular compartment typically within the endosomal system; and 3) exocytosis of the molecule to the … Visa mer Transcytosis (also known as cytopempsis) is a type of transcellular transport in which various macromolecules are transported across the interior of a cell. Macromolecules are captured in vesicles on one side of the … Visa mer Due to the function of transcytosis as a process that transports macromolecules across cells, it can be a convenient mechanism by which Visa mer • Macromolecules Can Be Transferred Across Epithelial Cell Sheets by Transcytosis • Transcytosis of IgA • Transcytosis of bacteria Visa mer The regulation of transcytosis varies greatly due to the many different tissues in which this process is observed. Various tissue-specific mechanisms of transcytosis have been identified.

ANTPs containing hemagglutinins (HAs) may have an additional role in altering the intercellular junctions and facilitating toxin passage through the paracellular way.
Webb11 jan. 2024 · Although initially thought to be attenuated in brain endothelial cells, virtually all endothelial cells display receptor-mediated transcytosis (RMT) (Stewart, 2000). Recent applications of imaging techniques allowed for detailed analyses of transcytosis in brain endothelial cells (Villasenor and Collin, 2024). Webb1 dec. 2024 · I have introduced several methods for transmembrane drug delivery [3,4,5,6,7,8,9,10], particularly for drug delivery into cancer cells across the membrane via RME using mAbs, cell-penetrating peptides (CPPs), and tumor-homing peptides (THPs) as ligands [5], and for drug delivery to brain cancer cells across the blood–brain barrier …
