Hydra polyps exposed to LPS treatments acti- vate the expression of the antimicrobial peptides in a dose-dependent manner, suggesting that LPS is an in- ducer of immune defenses in cnidarians [35]. Indeed, studies on corals have shown that LPS can trigger an im- mune response in several species and more specifically genes of the TLR-to-NF-κB pathway [34, 50]..

Antimicrobial peptide production is highest in the fat body and/or hemolymph, as is typical for insects [65]. Un- surprisingly we found high expression of the eponymous peptides oryctin and rhinocerosin, first discovered in Oryctes rhinoceros [9, 10]. The only antimicrobial peptide not produced in the fat body was thaumatin, which was highly and differentially expressed in the midgut (Table 3)..
