IFNG and neuroblastoma: The delivery of anti-class II-deglycosylated Ricin A chain caused destruction of IFN-γ-activated endothelial cells in vitro and complete thrombosis and decay of vasculature of neuroblastoma tumors in vivo suggesting that immunoconjugates attached with antibodies against tumor endothelium could offer extensive therapy to numerous solid tumors in humans [102].
