NAPPA-Based Vaccines for a New Proteogenomics Approach for Public Health

Abstract

Vaccinology was developed for the first time in 1796 when Jenner empirically implemented a vaccine against smallpox using animal-to-human cowpox inoculation. Since then, it has become a very complex science due to the merging of disciplines ranging from structural and functional, cellular and molecular biology and immunology to bioinformatics and nanobiotechnology, as well as systems biology and synthetic biology and engineering. In the frame of evidence-based medicine (EBM), evidence-based vaccinology emerged as an important sub-field: vaccinology has nowadays become more and more predictive and personalized. With the discovery that many patients with cancer develop antibodies against p53 (the so-called oncoantibodies), it was evident that oncoprotein are immunogenic and can be used for immunotherapeutics purposes. In this manuscript, we report Nucleic Acid Programmable Protein Arrays (NAPPA)-based Quartz Crystal Microbalance (QCM) measurement of p53 immunogenicity and kinetics, in the perspective of developing an effective p53 therapy. NAPPA-based QCM_D can be a useful platform for proving the immunogenicity of oncoprotein-based vaccines. Recently, the field of vaccinology has extended from vaccines for infectious diseases to vaccines not only preventive but also therapeutic for chronic-degenerative diseases such as cancer. Peptide-based immunotherapeutics has been proven to be quite effective for cancer treatment and NAPPA-based QCM_D has the promise of providing clinicians with quick, rapid and cheap measurement of oncoprotein kinetics and bindings with immune cells. Moreover, it can be a precious tool for implementing personalized and predictive vaccinology.
