Role of Anti-Cancer Peptides as Immunomodulatory Agents: Potential and Design Strategy

Area of Science:

• Biochemistry
• Immunology
• Pharmacology

Background:

• Peptide-based drugs are emerging as significant alternatives to traditional cancer therapies like chemotherapy and radiotherapy due to reduced collateral damage to normal cells.
• Antimicrobial peptides (AMPs) have demonstrated anticancer activity, but their immunomodulatory potential in cancer treatment remains underexplored.
• The intricate relationship between cancer and immune responses necessitates the development of molecules with combined anticancer and immunomodulatory properties.

Purpose of the Study:

• To comprehensively review naturally occurring and synthetic anticancer peptides with reported immunomodulatory activity.
• To explore the structural and biophysical parameters influencing the dual activity of these peptides.
• To emphasize the interconnectedness of anticancer and immunomodulatory effects for future peptide drug design.

Main Methods:

• Literature review of scientific publications on anticancer peptides.
• Analysis of studies reporting both anticancer and immunomodulatory activities of peptides.
• Assessment of structural and biophysical characteristics of identified peptides.

Main Results:

• A significant number of anticancer peptides exhibit immunomodulatory activity, often by inhibiting pro-inflammatory responses that promote cancer progression.
• Both natural and synthetic peptides have been identified with dual anticancer and immunomodulatory functions.
• Specific structural and biophysical features correlate with enhanced dual activity.

Conclusions:

• Anticancer peptides with immunomodulatory capabilities represent promising lead molecules for novel cancer therapeutics.
• Understanding the interplay between anticancer and immunomodulatory effects is crucial for designing effective peptide drugs.
• Further research into structural and biophysical optimization can enhance the therapeutic potential of these peptides.
