Amphihelical antimicrobial peptides (AMPs) are bactericidal host defense factors, but their function as immunomodulators is emerging. Here the authors show that several AMPs organize DNA into periodic nanocrystals by self-assembling into superhelical protofibril scaffolds, which potentiates DNA sensing by TLR9.
