1 The functionally related antitumor drugs 5,6-dimethylxanthenone-4-acetic acid (DMXAA) and flavone acetic acid (FAA), which cause tumor vasculature collapse and tumor necrosis, were used to attack the tumor vasculature, whereas the T-cell costimulator B7.1 (CD80), which costimulates T-cell proliferation via the CD28 pathway, was used to stimulate antitumor immunity. vadimezan CD80 antigen Mus musculus

5 Thus, a broad range of amounts of B7.1 cDNA were effective in combination with 25 mg/kg DMXAA. vadimezan CD80 antigen Mus musculus
6 In contrast, DMXAA, which has a very narrow range of high active doses, was effective at a low dose (18 mg/kg) when administered with a large amount (180 microg) of B7.1 cDNA. vadimezan CD80 antigen Mus musculus
