What is phagocytis?
In unicellular creatures, phagocytosis is a critical mechanism for nourishment; in multicellular organisms, it is a function of specialized cells called phagocytes. The process of phagocytosis entails the recognition and ingestion of particles larger than 0.5 m into a vesicle formed by the plasma membrane known as a phagosome. Importantly, phagocytes can also eat apoptotic cells in addition to microbial infections. They assist in clearing out the daily turnover of billions of cells in this way. Thus, phagocytosis becomes crucial for maintaining tissue homeostasis as well as the removal of microorganisms.
What type of proteins do the white blood cells look for in cell identification?
They look for pathogen specific or pathogen associated proteins presented by MHC molecules. However the also need interactions by co-receptors. These co-receptors are only expressed it the cells are exposed to pathogen associated molecular paterns. Ermm, that might not be the best answer but I hope you get the idea...
