Beschreibung:
Monoallelic point mutations of isocitrate dehydrogenase type 1 (IDH1) are an early and defining event in the development of a subgroup of gliomas and other types of tumour. They almost uniformly occur in the critical arginine residue (Arg 132) in the catalytic pocket, resulting in a neomorphic enzymatic function, production of the oncometabolite 2-hydroxyglutarate (2-HG), genomic hypermethylation, genetic instability and malignant transformation. More than 70% of diffuse grade II and grade III gliomas carry the most frequent mutation, IDH1(R132H) (ref. 3). From an immunological perspective, IDH1(R132H) represents a potential target for immunotherapy as it is a tumour-specific potential neoantigen with high uniformity and penetrance expressed in all tumour cells. Here we demonstrate that IDH1(R132H) contains an immunogenic epitope suitable for mutation-specific vaccination. Peptides encompassing the mutated region are presented on major histocompatibility complexes (MHC) class II and induce mutation-specific CD4(+) T-helper-1 (TH1) responses. CD4(+) TH1 cells and antibodies spontaneously occurring in patients with IDH1(R132H)-mutated gliomas specifically recognize IDH1(R132H). Peptide vaccination of mice devoid of mouse MHC and transgenic for human MHC class I and II with IDH1(R132H) p123-142 results in an effective MHC class II-restricted mutation-specific antitumour immune response and control of pre-established syngeneic IDH1(R132H)-expressing tumours in a CD4(+) T-cell-dependent manner. As IDH1(R132H) is present in all tumour cells of these slow-growing gliomas, a mutation-specific anti-IDH1(R132H) vaccine may represent a viable novel therapeutic strategy for IDH1(R132H)-mutated tumours.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schumacher, Theresa -- Bunse, Lukas -- Pusch, Stefan -- Sahm, Felix -- Wiestler, Benedikt -- Quandt, Jasmin -- Menn, Oliver -- Osswald, Matthias -- Oezen, Iris -- Ott, Martina -- Keil, Melanie -- Balss, Jorg -- Rauschenbach, Katharina -- Grabowska, Agnieszka K -- Vogler, Isabel -- Diekmann, Jan -- Trautwein, Nico -- Eichmuller, Stefan B -- Okun, Jurgen -- Stevanovic, Stefan -- Riemer, Angelika B -- Sahin, Ugur -- Friese, Manuel A -- Beckhove, Philipp -- von Deimling, Andreas -- Wick, Wolfgang -- Platten, Michael -- England -- Nature. 2014 Aug 21;512(7514):324-7. doi: 10.1038/nature13387.
