The evidence is convincing, and these findings contribute important information towards the selection of neoantigens for personalized antitumor vaccination. |\n| --- |\n| Abstract In this study, we present a proof-of-concept classical vaccination experiment that validates the in silico identification of tumor neoantigens (TNAs) using a machine learning-based platform called NAP-CNB. Unlike other TNA predictors, NAP-CNB leverages RNA-seq data to consider the relative expression of neoantigens in tumors. Our experiments show the efficacy of NAP-CNB. Predicted TNAs elicited potent antitumor responses in mice following classical vaccination protocols. Notably, optimal antitumor activity was observed when targeting the antigen with higher expression in the tumor, which was not the most immunogenic. Additionally, the vaccination combining different neoantigens resulted in vastly improved responses compared to each one individually, showing the worth of multiantigen-based approaches. These findings validate NAP-CNB asan innovative TNA identification platform and make a substantial contribution to advancing the next generation of personalized immunotherapies. |\n\nIntroduction  \nA new window of hope to treat previously intractable tumors is emerging through immunotherapies (Chen and Mellman, 2013) . However, the response rates of these therapies remain low and relapses are common (Kalbasi and Ribas, 2020; Novello et al., 2023) .
