Vaccination in glioblastomas does lead to the emergence of tumour-antigen-specific T cells but T cell dysfunction, poor tumour infiltration and persistence hinder efficient tumour killing. Here authors identify a T cell receptor in a vaccinated glioblastoma patient that specifically recognizes the glioblastoma stem cell antigen PTPRZ1 and utilise it in T cell receptor-engineered T (TCR-T) cell therapy, resulting in efficient tumour cell killing in vitro and in a mouse model.
