title: Identification of a naturally processed T cell epitope derived from the glioma-associated protein SOX11.
abstract: The development of T cell-based immunotherapies of cancer depends on the identification of tumor-associated antigens capable of eliciting tumor-directed cytotoxic T cell responses. In malignant glioma the number of well-defined target antigens for cytotoxic T lymphocytes (CTLs) is still very limited. Recently, we demonstrated the abundant and specific overexpression of the transcription factor SOX11 in malignant glioma. Here, we describe the SOX11-derived peptide LLRRYNVAKV which is capable of inducing human leukocyte antigen-A*0201-restricted and tumor-reactive CTLs. This novel CTL epitope may serve as an attractive candidate for a T cell-based immunotherapy of glioma.
