FABP7 and glioblastoma: On the other hand, peptide elution from GBM cells was demonstrated capable of identifying 10 novel GBM-associated antigens, brevican, chitinase 3-like 2, Chondroitin sulphate proteoglycan, fatty acid-binding protein 7, insulin-like growth factor 2 messenger RNA-binding protein 3, neuroligin 4, X-linked, neuronal cell adhesion molecule, protein tyrosine phosphatase, receptor-type, Z polypeptide, tenascin C, were overexpressed in 80–100% of GBM patients, making a peptide vaccine possible [51].
