Cancer Vaccines

597
Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

Area of Science:

  • Biomaterials Science
  • Immunology
  • Vaccine Technology

Background:

  • Current vaccines face challenges with safety, reactogenicity, and immunogenicity.
  • Subunit vaccines require adjuvants to enhance immune responses, often leading to side effects.
  • Nanomaterial-based platforms are being developed to improve vaccine efficacy and safety.

Purpose of the Study:

  • To review the use of self-assembling peptide-, peptidomimetic-, and protein-based biomaterials in vaccine development.
  • To highlight the self-adjuvanting properties of these biomaterials.
  • To discuss their application in modulating innate and adaptive immunity for various diseases.

Main Methods:

  • Review of existing literature on self-assembling biomaterials for vaccines.
  • Discussion of structural determinants of various biomaterial architectures (coiled coils, β-sheets, peptide amphiphiles, protein nanoparticles).
  • Highlighting examples of innate and adaptive immunomodulatory capacity.

Main Results:

  • Self-assembling biomaterials offer modularity, multivalency, and biocompatibility.
  • These scaffolds are recognized by the immune system and function as self-adjuvanting delivery vehicles.
  • They enhance both humoral and cellular immune responses.
  • Facile design and modification allow for tailored vaccines and generalizable platforms.

Conclusions:

  • Self-assembling biomaterials present a viable strategy to overcome limitations of current vaccines.
  • Their inherent self-adjuvanting capacity improves immunogenicity and safety profiles.
  • These platforms show potential for preventing and treating a wide range of infectious and non-infectious diseases.
