PTPRZ1 and glioblastoma: In this study, we profiled the expression of PTPRZ1, a glioblastoma-associated antigen and GSC marker, across bulk and scRNA-seq datasets in publicly available and own cohorts and took advantage of a previous multinational European glioblastoma vaccination trial, enabling us to retrieve an HLA-A*02-restricted PTPRZ1-reactive TCR in a reverse translation research paradigm.
