CD274 and neoplasm: (23), using a single-domain anti-CD20 antibody in immunocompetent mice with CD20-expressing subcutaneous tumors, found a modest therapeutic effect at 140 MBq/mouse; 50 MBq/mouse induced expression of proinflammatory genes, whereas 140 MBq/mouse increased the percentage in the tumor of PD-L1–positive myeloid cells and alternatively activated macrophages.
