====== Carbonic anhydrase 9 ====== Zhang et al. presented recent preclinical and clinical studies targeting well-characterized [[glioblastoma]] [[antigen]]s, which include the [[IL13RA2]] and the [[epidermal growth factor receptor]]. Afterward, they turn their attention to alternative [[target]]s in [[glioblastoma]], including less-explored antigens such as B7-H3 ([[CD276]]), [[carbonic anhydrase 9]], and the [[GD2]] [[ganglioside]]. They also discuss additional target ligands, namely [[CD70]], and [[NKG2D]]. Finally, they present the possibilities afforded by novel CAR architectures. In particular, they examine the use of armored CARs to improve the survival and proliferation of CAR T cells. They conclude by discussing the advantages of tandem and synNotch CARs when targeting multiple GBM antigens ((Zhang J, Siller-Farfán JA.
