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. Brefeldin A , a commonly used inhibitor of ER -to- Golgi apparatus transport, has been shown to inhibit transcytosis in dog kidney cells, which provided the ...
Transcytosis is the movement of large molecules across the interior of a cell. This process occurs by engulfing the molecule as it moves across the interior of the cell and then releasing the molecule on the other side. There are two types of transcytosis are receptor-mediated transcytosis (RMT) and adsorptive-mediated transcytosis (AMT).
The process of transporting polymeric immunoglobulins from the basolateral to apical side, known as transcytosis, is composed of several distinct steps. Transcytosis is initiated by either the binding of dimeric IgA to the receptor or the phosphorylation of Ser-664 residue of the receptor. [9]
Transcytosis can also be taken advantage of by pathogenic molecules and organisms. Several studies have shown that bacterium can easily enter intestinal lumen through transcytosis of goblet cells. [7] Other studies, however, are exploring the idea that transcytosis may play a role in allowing medications to cross the blood-brain barrier.
After internalization of microvesicle via endocytosis, the endosome may move across the cell and fuse with the plasma membrane, a process called transcytosis. This results in the ejection of the microvesicle back into the extracellular space or may result in the transportation of the microvesicle into a neighboring cell. [3]
Specialized phagocytic cells, called M cells, which are found in the epithelial layer of the Peyer’s patches, can transport antigenic material across the intestinal barrier through the process of transcytosis. [15]
For example, in epithelial cells, a special process called transcytosis allows some materials to enter one side of a cell and exit from the opposite side. Also, in some circumstances, late endosomes/MVBs fuse with the plasma membrane instead of with lysosomes, releasing the lumenal vesicles, now called exosomes , into the extracellular medium.
Low density lipoprotein receptor-related protein 1 (LRP1), also known as alpha-2-macroglobulin receptor (A2MR), apolipoprotein E receptor (APOER) or cluster of differentiation 91 (CD91), is a protein forming a receptor found in the plasma membrane of cells involved in receptor-mediated endocytosis.
