Research Article: Peptide-Based Therapeutic HPV Cancer Vaccine Synthesized via Bacterial Outer Membrane Vesicles

Date Published: 2023-08-08

Abstract:
Immunotherapy is considered a potential cancer treatment strategy, in which therapeutic cancer vaccines are an important factor. The effectiveness of therapeutic cancer vaccines has been demonstrated in a variety of cancer types. At present, the therapeutic cancer vaccine strategy targeting screened personalized neoantigens has gradually shown great application prospects. Enabling the simultaneous display of multiple tumor antigens by linking antigens using a plug-and-play system may be a valuable approach for the development of personalized tumor vaccines against complex and heterogeneous tumor antigens., Recently, peptide-based vaccines have received increasing attention in both infectious disease and cancer research fields because of their convenient preparation, high safety, and favorable immunogenicity. Peptide-based vaccines can be intelligently designed to target specific MHC molecules for efficient presentation, thereby enhancing B-cell and T-cell responses. An advantage of peptide-based vaccines is that they are easy to synthesize, eliminating the need for many tedious processes, such as the expression and purification of vaccine antigens and in vitro transcription of nucleic acid vaccines. Peptide-based vaccines can be easily obtained through artificial synthesis, and have high purity. However, although artificially synthesized peptides are convenient, they have a higher cost. In addition, peptide-based vaccines generally require a suitable delivery system to protect and deliver the peptide, which increases the cost and complexity of peptide-based vaccine preparation.
