Antimicrobial peptides are crucial for innate immunity across all organisms. These membrane-disrupting molecules show significant potential as novel therapeutics against microbial infections.

Area of Science:

  • Immunology
  • Biochemistry
  • Microbiology

Background:

  • Organisms require defense against microorganisms like bacteria, viruses, and fungi.
  • Adaptive immunity, while sophisticated, is limited to higher animals.
  • Innate immunity, present in all living creatures, relies on ancient defense mechanisms.

Purpose of the Study:

  • To review the functional and structural characteristics of naturally occurring antimicrobial peptides.
  • To explore the role of membrane-active peptides and proteins in both innate and adaptive immunity.
  • To discuss the therapeutic potential of antimicrobial peptides.

Main Methods:

  • Literature review focusing on antimicrobial peptides.
  • Analysis of structural and functional features of these peptides.
