Drosophila melanogaster Host Defense
Drosophila melanogaster relies on innate immunity, which is often shared from higher organisms. There are physical barriers, such as epithelia and there are hemocytes which act as a secondary immune response to pathogen. Along with the physical barrier, epithelia also contain antimicrobial peptides, as well as oxygen species which are highly reactive. The last immune response that the Drosophila melanogaster relies on against pathogens is the fat body, which is comparable to the liver.1 Drosophila melanogaster have an impressive immune response, similar to that of humans and is likely do to the common genomics between species.
