The secretion of anti-microbial peptides is recognised as an essential step in innate immunity, but there is limited knowledge of the molecular mechanism controlling the release of these effectors from immune response cells. Here, we report that Drosophila 14-3-3ε mutants exhibit reduced survival when infected with either Gram-positive or Gram-negative bacteria, indicating a functional role for...

Recently, antimicrobial peptides have been introduced as potent antibiotics with a wide rangeof antimicrobial activities. They have also exhibited other biological activities, including antiinflammatory,growth stimulating, and anti-cancer activities. In this study, an analog of MagaininII was designed and produced as a recombinant fusion protein. The designed sequence containe...

Cationic antimicrobial peptides (CAMPs) are important innate immune defenses that inhibit colonization by pathogens and contribute to clearance of infections. Gram-negative bacterial pathogens are a major target, yet many of them have evolved mechanisms to resist these antimicrobials. These resistance mechanisms can be critical contributors to bacterial virulence and are often crucial for survi...

independent pathways. through both phoP-dependent and RpoS (sigma(S)) independent and occurs polymyxin B in Salmonella typhimurium is resistance to the antimicrobial peptide Starvation-and Stationary-phase-induced

The need for novel antibiotics in an era where antimicrobial resistance is on the rise, and the number of new approved antimicrobial drugs reaching the market is declining, is evident. The underused potential of post-translationally modified peptides for clinical use makes this class of peptides interesting candidates. In this study, we made use of the vast amounts of available genomic data and...

Virulent group A streptococci have become a serious threat, with the emergence of the hypervirulent lineage M1T1. In this issue of Cell Host & Microbe, LaRock et al. (2015), uncover a role for the streptococcal M1 protein in neutralizing a key human antimicrobial peptide, cathelicidin.
