Cationic host defense (antimicrobial) peptides
Current Opinion in Immunology, 2006Members of the cationic host defense (antimicrobial) peptide family are widely distributed in nature, existing in organisms from insects to plants to mammals and non-mammalian vertebrates. Although many demonstrate direct antimicrobial activity against bacteria, fungi, eukaryotic parasites and/or viruses, it has been established that cationic peptides ...

Membrane targeting cationic antimicrobial peptides
Journal of Colloid and Interface Science, 2019Many short cationic peptides are amphiphilic and are often termed antimicrobial peptides (AMPs) as they can kill various microorganisms. These AMPs have largely been discovered from nature, but over the past two decades many biomimetic and de novo designed AMPs have been reported, offering a huge variety of attractive properties for further ...

Phage-Encoded Cationic Antimicrobial Peptide Required for Lysis
Journal of Bacteriology, 2022We provide evidence that phiKT produces an antimicrobial peptide for outer membrane disruption during lysis. This protein, designated a disruptin, is a new paradigm for phage lysis and has no similarities to other known lysis genes.

Bacterial resistance to cationic antimicrobial peptides
Critical Reviews in Microbiology, 2012Naturally occurring cationic antimicrobial peptides (CAMPs) have been considered as promising candidates to treat infections caused by pathogenic bacteria to animals and humans. This assumption is based on their mechanism of action, which is mainly performed through electrostatic membrane interactions.

Cationic Antimicrobial Peptides in Penaeid Shrimp
Marine Biotechnology, 2010Penaeid shrimp aquaculture has been consistently affected worldwide by devastating diseases that cause a severe loss in production. To fight a variety of harmful microbes in the surrounding environment, particularly at high densities (of which intensive farming represents an extreme example), shrimps have evolved and use a diverse array of ...

The Pharmacology of Radiolabeled Cationic Antimicrobial Peptides
Journal of Pharmaceutical Sciences, 2008Cationic antimicrobial peptides are good candidates for new diagnostics and antimicrobial agents. They can rapidly kill a broad range of microbes and have additional activities that have impact on the quality and effectiveness of innate responses and inflammation.

Antiendotoxin activity of cationic peptide antimicrobial agents
Infection and Immunity, 1996The endotoxin from gram-negative bacteria consists of a molecule lipopolysaccharide (LPS) which can be shed by bacteria during antimicrobial therapy. A resulting syndrome, endotoxic shock, is a leading cause of death in the developed world. Thus, there is great interest in the development of antimicrobial agents which can reverse rather than promote ...

Cationic Antimicrobial Peptides
BioDrugs, 2003Many different types of organisms use antimicrobial peptides, typically 20-40 amino acids in length, for defence against infection. Most are capable of rapidly killing a wide range of microbial cells. They have been classified according to their active structures into six extensive groups.

A Review of Antimicrobial Peptides: Defensins and Related Cationic Peptides
Veterinary Clinical Pathology, 1995Cationic antimicrobial peptides are present throughout the plant and animal kingdoms and bear striking structural and functional similarities across species lines. They provide primitive, nonspecific means of combating a variety of bacteria, fungi, enveloped viruses, and protozoa.

Cationic Antimicrobial Peptides—The Defensins
2006The term defensin relates different families of host defense peptides (HDPs) in vertebrates, invertebrates, plants, and molds that display structural similarities based on a cystine stabilized antiparallel b-sheet core, with an N-terminal a-helical stretch in many members.
