These and subsequent studies have uncovered the functional roles of specific AMPs such as Cecropin (Cec) [24–26], Diptericin (Dpt) [22,27,28], Defensin (Def) [29,30] and Drosomycin (Drs) [31–33], as well as the dynamics of their transcriptional activation during infection. This evidence concerns the gene DPT and infection.
