abstract = {The immune peptidome of OPSCC has not previously been
studied. Cancer-antigen specific vaccination may improve
clinical outcome and efficacy of immune checkpoint
inhibitors such as PD1/PD-L1 antibodies.Mapping of the OPSCC
HLA ligandome was performed by mass spectrometry (MS) based
analysis of naturally presented HLA ligands isolated from
tumour tissue samples (n = 40) using immunoaffinity
purification. The cohort included 22 HPV-positive (primarily
HPV-16) and 18 HPV-negative samples. A benign reference
dataset comprised of the HLA ligandomes of benign
haematological and tissue datasets was used to identify
tumour-associated antigens.MS analysis led to the
identification of naturally HLA-presented peptides in OPSCC
tumour tissue. In total, 22,769 peptides from 9485 source
proteins were detected on HLA class I. For HLA class II,
15,203 peptides from 4634 source proteins were discovered.
By comparative profiling against the benign HLA ligandomic
datasets, 29 OPSCC-associated HLA class I ligands covering
11 different HLA allotypes and nine HLA class II ligands
were selected to create a peptide
warehouse.Tumour-associated peptides are HLA-presented on
the cell surfaces of OPSCCs. The established warehouse of
OPSCC-associated peptides can be used for downstream
immunogenicity testing and peptide-based immunotherapy in
(semi)personalised strategies.},
