transcytosis

Examples of transcytosis in the following topics:

• Transcytosis

  • Transcytosis is a process by which molecules are transported into the capillaries.
  • Transcytosis, or vesicle transport, is one of three mechanisms that facilitate capillary exchange, along with diffusion and bulk flow.
  • Due to the function of transcytosis, it can be a convenient mechanism by which pathogens can invade a tissue.
  • Listeria monocytogenes has been shown to enter the intestinal lumen via transcytosis across goblet cells.
  • These examples illustrate that transcytosis is vital to the process of pathogenesis for a variety of infectious agents.

• Bulk Flow: Filtration and Reabsorption

  • Capillary fluid movement occurs as a result of diffusion (colloid osmotic pressure), transcytosis, and filtration.
  • Bulk flow is one of three mechanisms that facilitate capillary exchange, along with diffusion and transcytosis.

• Capillary Dynamics

  • There are three mechanisms that facilitate capillary exchange: diffusion, transcytosis, and bulk flow.
  • Transcytosis is the mechanism whereby large, lipid-insoluble substances cross the capillary membranes.
