“…They appear to invade normal brain along the white matter tracts, around nerve cells, and along perivascular spaces. The classical therapeutic triad for malignant brain tumors includes neurosurgery, radiation, and chemotherapy, while novel immunotherapeutic approaches that target antigens involved in angiogenesis, migration, and/or growth factor receptors have recently shown promise in clinical trials (Brown et al, 1996;Bigner et al, 1998). To rapidly identify novel targets for immunotherapeutic approaches, we have employed a strategy that combines subtractive cloning with cDNA array screening for target identification.…”
