Biological Function of Antimicrobial Peptides on Suppressing Pathogens and Improving Host Immunity

Area of Science:

• Biotechnology
• Immunology
• Drug Discovery

Background:

• Rising antibiotic resistance and food safety concerns necessitate novel therapeutic strategies.
• Overuse of antibiotics in livestock and human medicine has led to the emergence of resistant pathogens.
• Antimicrobial peptides (AMPs) are a potential alternative due to their pathogen-killing and immune-enhancing properties.

Purpose of the Study:

• To review the potential of antimicrobial peptides (AMPs) as antibiotic substitutes.
• To explore how AMPs enhance host immunity and combat pathogens.
• To discuss the challenges and future prospects of AMPs in livestock production and human medicine.

Main Methods:

• Review of existing literature on antimicrobial peptides (AMPs).
• Analysis of AMPs' structure-activity relationships and mechanisms of action.
• Examination of signaling pathways (NF-κB, MAPK) involved in AMP-mediated immune responses.

Main Results:

• Antimicrobial peptides (AMPs) demonstrate broad-spectrum antimicrobial activity.
• AMPs modulate host immune cells and inflammatory responses.
• Pathogen resistance to AMPs is less common than to conventional antibiotics.

Conclusions:

• Antimicrobial peptides (AMPs) are effective alternatives to antibiotics, offering pathogen suppression and immune enhancement.
• Challenges such as limited sources, high production costs, and instability need to be addressed for widespread application.
• Further research is crucial for the successful commercialization of AMPs in animal husbandry and human medicine.
