The source of Antimicrobial Peptides (AMPs) includes mammals, amphibians, fish, microorganisms, and insects.
Sources of Antimicrobial Peptides (AMPs)
Antimicrobial Peptides (AMPs) are a diverse group of molecules produced by a wide variety of organisms. These peptides play a crucial role in the innate immune system, offering protection against various pathogens. According to the provided reference, AMPs can be categorized based on their origin, including:
- Mammals: Also known as human host defence peptides, these AMPs are part of the mammalian immune response.
- Amphibians and Fish: These animals produce AMPs as a defense mechanism against infections in their environments.
- Microorganisms: Certain microorganisms synthesize AMPs to compete with other microbes or for self-defense.
- Insects: Insects utilize AMPs as a key component of their immune system.
AMP Source Categories in Table Form
| Source Category | Examples |
|---|---|
| Mammals | Human defensins, cathelicidins |
| Amphibians/Fish | Magainins (frogs), piscidins (fish) |
| Microorganisms | Bacteriocins |
| Insects | Cecropins, defensins |
This diversity in origin underscores the importance of AMPs as a widespread defense mechanism across various life forms.
