Phagocytes

Which two phagocytes are recruited to the site of infection?

Macrophages and neutrophils.

What do phagocytes use to recognize pathogens?

Cell surface receptors that recognize either an opsonin or molecular patterns on the pathogen's surface.

What happens when receptors on a phagocyte bind to a pathogen?

The receptors cluster, and the pathogen is ingested into a membrane-enclosed phagosome.

What is formed when a phagosome fuses with a lysosome?

A phagolysosome with a low pH and digestive enzymes to destroy and degrade the pathogen.
