Antimicrobial peptides: The miraculous biological molecules

Area of Science:

• Immunology
• Microbiology
• Biochemistry

Background:

• Antimicrobial peptides (AMPs) are key components of the innate and acquired immune systems.
• AMPs exhibit broad-spectrum activity against bacteria, fungi, and viruses.
• In the oral cavity, AMPs secreted by various cells and fluids provide the first line of defense against microbial invasion.

Purpose of the Study:

• To review the current literature on antimicrobial peptides (AMPs).
• To evaluate the therapeutic potential of AMPs in various applications.
• To explore the role of AMPs in oral health and periodontal disease.

Main Methods:

• Literature review encompassing reviews, systematic reviews, and original research.
• Analysis of AMPs' activity spectrum and resistance development.
• Investigation of AMPs' function in oral cavity and periodontal disease progression.

Main Results:

• AMPs demonstrate potent antimicrobial activity with minimal resistance development, making them ideal candidates for novel antibiotics.
• AMPs have shown promise in therapeutic applications like mouthwashes and topical treatments, though further trials are ongoing.
• AMPs function as biomarkers in periodontal disease, with their expression levels changing during disease progression.

Conclusions:

• AMPs are versatile molecules with significant therapeutic potential for infectious diseases and oral health.
• Early detection of AMP biomarker changes can aid in managing periodontal disease progression.
• AMPs are crucial in controlling biofilm formation and may lead to future developments in therapeutics like mimetics, probiotics, and antibiotics.
