Exploring pathological link between antimicrobial and amyloid peptides

Area of Science:

• Biochemistry
• Molecular Biology
• Pathology

Background:

• Amyloid peptides (AMYs) and antimicrobial peptides (AMPs) are distinct peptide families.
• Emerging evidence links AMYs and AMPs in neurodegenerative diseases and microbial infections.
• Shared structural and functional characteristics exist between AMYs and AMPs.

Purpose of the Study:

• To review recent developments in the interplay between AMYs and AMPs.
• To examine the pathological implications of AMY-AMP interactions in disease.
• To highlight challenges and inspire future research in this field.

Main Methods:

• Literature review of existing studies on AMY-AMP interactions.
• Analysis of shared structural and functional properties.
• Discussion of cross-seeding phenomena and bidirectional communication.

Main Results:

• AMYs can exhibit antimicrobial activity, and AMPs can display amyloidogenic properties.
• Cross-seeding between AMYs and AMPs is a key factor in disease pathogenesis.
• The interplay influences both neurodegeneration and host defense mechanisms.

Conclusions:

• The molecular crosstalk between AMYs and AMPs is crucial in infectious and neurodegenerative diseases.
• Further research is needed to fully understand these interactions.
• This knowledge can lead to innovative therapeutic strategies for multiple disorders.
