GAD2 and neoplasm: Furthermore, analysis of canonical neuronal markers (Supplementary Fig. S5B) showed that malignant cells expressed, in addition to pan-neuronal markers (SNAP25 and STMN2), pan-GABAergic markers (GAD1 or GAD2) or other interneuron markers (LHX6, SST, DLX5, DLX6, or NXPH1) with negligible expression of the pan-glutamatergic marker SLC17A7 (Supplementary Fig. S5C), including in the tumor in which automated labeling had failed to identify inhibitory neuronal populations.
