What does a dendritic cell look like?
Dendritic cells have long finger like processes, like the dendrites of nerve cells, which give them their name.
What is the function of a dendritic cell?
They take up particulate matter by phagocytosis and also continually ingest large amounts of the extracellular fluid and its contents by a process known as macropinocytosis.
They degrade the pathogens they take up and present them to T lymphocytes, which activates them and for this reason dendritic cells are also called antigen-presenting cells (APCs).
Dendritic cells form a crucial link between the innate immune response and the adaptive immune response. (Just like the messenger is a link between the border and the military base!)
Did you know?
Dendritic cells express a lot of MHC class II molecules making them very efficient in antigen presentation.
It's like they were born to present antigens!
