## Abstract We first classified 12 malignant glioma cell lines into three different groups (types 1β3) with respect to major histocompatibility complex (MHC) class II expression and analyzed each group based on the different expression status of the class II transactivator (CIITA) gene. Glioma type
Activation of T lymphocytes is quantitatively controlled by the level of expression of MHC class II molecules. Both constitutive and inducible expression of MHC class II genes is regulated by the transactivator CIITA, which is itself tightly regulated. Since the level of MHC class II molecules expre
