F10 and neoplasm: These molecules include immune-cell engagers (bringing immune cells to tumor cells to proximity for killing), antibody-drug conjugates (delivering small molecule drugs to target location via antibody), tetherbodies (enriching target molecules (cytokines or immunotoxin) into specific tissue/cellular locations), and biologic matchmaker drugs (close proximity to an action partner, e.g., emicizumab that brings substate Factor X (FX) to protease Factor IXa (FIXa) for cleavage).
