INPP4B and glioma: To further test the effect of INPP4B expression in glioma cells on their ability to inhibit T cell proliferation, after transfecting the U87 cells for 48 h with pcDNA3.1-Scramble or pcDNA3.1-INPP4B, CSFE-labeled Jurkat cells were added to the cultured and analysed for proliferation.
