From inside to outside: exploring extracellular antimicrobial histone-derived peptides as multi-talented molecules

Area of Science:

• Microbiology
• Biochemistry
• Drug Discovery

Background:

• Antibiotic resistance is a growing global health crisis, increasing morbidity and mortality.
• Antimicrobial peptides (AMPs) are a potential alternative to conventional antibiotics.
• Histones, known for DNA packaging, also exhibit antimicrobial and immunomodulatory functions extracellularly.

Purpose of the Study:

• To review histone-derived antimicrobial peptides (AMPs) across various organisms.
• To elucidate the mechanisms of action for these histone-derived AMPs.
• To explore the potential of extracellular histones in antimicrobial drug delivery systems.

Main Methods:

• Literature review of the Antimicrobial Peptide Database and relevant scientific publications.
• Analysis of existing data on histone structure, function, and antimicrobial properties.
• Synthesis of information regarding the application of histone-derived peptides in combating bacterial infections.

Main Results:

• The Antimicrobial Peptide Database contains 3569 cataloged peptides, highlighting a rich resource for drug development.
• Histones possess inherent antimicrobial activities and immunomodulatory properties.
• Extracellular histones demonstrate potential as components of novel drug delivery systems.

Conclusions:

• Histone-derived peptides represent a promising therapeutic strategy against antibiotic-resistant bacteria.
• Further research into histone-derived AMPs could lead to innovative treatments for bacterial infections.
• Extracellular histones offer a potential platform for developing advanced antimicrobial drug delivery systems.
