Báo cáo khoa học: Dermaseptin DA4, although closely related to dermaseptin B2, presents chemotactic and Gram-negative selective bactericidal activities

Antimicrobial peptides participate in innate host defense by directly elimi-nating pathogens as a result of their ability to damage the microbial mem-brane and by providing danger signals that will recruit innate immune cells to the site of infection. Dermaseptin DA4 (DRS-DA4), a new antimicrobial peptide of the dermaseptin superfamily, was identified based on its chemo-tactic properties, contrasting with the currently used microbicidal proper-ties assessment.
