Immunomodulatory Peptides for Tumor Treatment

Area of Science:

• Immunology
• Biochemistry
• Nanotechnology

Background:

• Peptides possess biological activities crucial for tumor immunotherapy, including immune cell stimulation.
• Current research extensively reviews peptides for chemotherapy, but peptide-mediated tumor immunotherapy remains underexplored.
• Peptide self-assemblies and nanocarriers improve peptide delivery and efficacy by overcoming biological barriers and degradation.

Purpose of the Study:

• To provide a comprehensive review of peptide-mediated tumor immunotherapy focusing on immunomodulatory anticancer peptides.
• To elucidate the role of peptides in modulating innate and adaptive immune cells and their interactions.
• To discuss peptide delivery strategies, including self-assemblies and nanocarrier functionalization.

Main Methods:

• Literature review of existing research on peptides in cancer immunotherapy.
• Classification of peptides based on their immunomodulatory effects on innate and adaptive immune cells and immune checkpoints.
• Analysis of peptide self-assemblies and peptide-functionalized nanocarriers as drug delivery systems.

Main Results:

• Peptides play a significant role in modulating both innate and adaptive immune responses against tumors.
• Effective delivery systems like peptide self-assemblies and nanocarriers enhance peptide stability and therapeutic outcomes.
• The review categorizes peptides by their specific immune cell targets and effects on immune checkpoints.

Conclusions:

• Peptides hold significant promise for advancing tumor immunotherapy by modulating immune responses.
• Optimized delivery strategies are essential for maximizing the therapeutic potential of anticancer peptides.
• Further research is needed to address challenges and fully realize the potential of peptides in cancer treatment.
