abstract = {Immunotherapies, including immune checkpoint blockades,
play a critically important role in cancer treatments. For
immunotherapies, neoantigens, which are generated by somatic
mutations in cancer cells, are thought to be good targets
due to their tumor specificity. Because neoantigens are
unique in individual cancers, it is challenging to develop
personalized immunotherapy targeting neoantigens. In this
study, we screened 'shared neoantigens', which are specific
types of neoantigens derived from mutations observed
commonly in a subset of cancer patients. Using exome
sequencing data in the Cancer Genome Atlas (TCGA), we
predicted shared neoantigen peptides and performed in vitro
screening of shared neoantigen-reactive CD8+ T cells using
peripheral blood from healthy donors. We examined the
functional activity of neoantigen-specific T cell receptors
(TCRs) by generating TCR-engineered T cells. Among the
predicted shared neoantigens from TCGA data, we found that
the mutated FGFR3Y373C peptide induced antigen-specific CD8+
T cells from the donor with HLA-A*02:06 via an ELISPOT
assay. Subsequently, we obtained FGFR3Y373C-specific CD8+ T
cell clones and identified two different sets of TCRs
specifically reactive to FGFR3Y373C. We found that the
TCR-engineered T cells expressing FGFR3Y373C-specific TCRs
recognized the mutated FGFR3Y373C peptide but not the
corresponding wild-type peptide. These two
FGFR3Y373C-specific TCR-engineered T cells showed cytotoxic
activity against mutated FGFR3Y373C-loaded cells. These
results imply the possibility of strategies of
immunotherapies targeting shared neoantigens, including
cancer vaccines and TCR-engineered T cell therapies.},
