Secretory Pathway

The Secretory Pathway is a series of steps that is used by cells to make and secrete proteins, lipids and many other molecules. This is a vital process for cells to carry out many of their functions and maintain the health of their environment. These steps involve a complex network of organelles and other cellular components that move the molecules from within the cell to the outside. These steps involve the synthesis of proteins, their packaging in vesicles, transport to the plasma membrane and, ultimately, secretion of the molecules either by exocytosis or transcytosis. Secretory Pathway is important in many areas including cell biology, biochemistry, immunology and drug development, as a better understanding of this process may facilitate the development of new therapeutic approaches.
