Furthermore, a group from Stanford University reported successful developments in immune system visualization techniques using OX40 mAb for imaging OX40+ activated T cells in a mouse model of syngeneic lymphoma (32) and 89Zr-DFO-ICOS mAb tracer, for detecting ICOS+ T cells in a murine lung cancer model (33). This evidence concerns the gene TNFRSF4 and lung cancer.
