Modulation of major histocompatibility complex Class I molecules and major histocompatibility complex—bound immunogenic peptides induced by interferon-α and interferon-γ treatment of human glioblastoma multiforme

Abstract

Interferon-alpha and IFN-gamma can significantly upregulate the MHC Class I molecules that are expressed on the cell surface of human GBM cells as well as the potentially immunogenic peptides bound to the MHC. These results may help explain the molecular basis for increased immunogenicity with IFN treatment of human GBMs and might provide added insight into the design of future antitumor vaccines for human brain tumors.
