Antimicrobial Proteins: Structure, Molecular Action, and Therapeutic Potential

Area of Science:

• Biochemistry
• Microbiology
• Pharmacology

Background:

• Antibiotic resistance is a growing global health crisis, limiting treatment options for severe infections.
• Traditional antibiotic pipelines are depleted, necessitating novel antimicrobial strategies.
• Clinical practices like cancer therapy and organ transplantation depend on effective infection control.

Purpose of the Study:

• To review the structure, molecular mechanisms, and therapeutic applications of antimicrobial peptides (AMPs).
• To highlight AMPs as a potential solution to combat multi-drug resistant pathogens.
• To explore the multifaceted biological roles of AMPs beyond antimicrobial activity.

Main Methods:

• Literature review of recent research on antimicrobial peptides.
• Analysis of AMP structure-activity relationships.
• Evaluation of AMPs' therapeutic potential and biological functions.

Main Results:

• Antimicrobial peptides exhibit broad-spectrum activity, high pathogen specificity, and low toxicity.
• AMPs are involved in immune regulation, angiogenesis, wound healing, and antitumor activities.
• The discovery and development of AMPs are gaining significant attention from researchers and the pharmaceutical industry.

Conclusions:

• Antimicrobial peptides represent a promising alternative to conventional antibiotics for treating resistant infections.
• AMPs possess diverse biological functions, enhancing their therapeutic relevance.
• Further research into AMPs is crucial for developing new strategies against the rising threat of antimicrobial resistance.
