Drosophila melanogaster harbors at least eight classes of AMPs, including lysozyme, defensins, cecropins, drosocin, attacins, diptericin, Maturated Pro-domain of Attain C (MPAC), drosomycin, and metchnikowin, all of which are synthesized by the fat body in response to infection and then secreted into the hemolymph15. The gene discussed is ADSL; the disease is infection.
