Trifunctional antibody-cytokine fusion protein formats for tumor-targeted combination of IL-15 with IL-7 or IL-21
Cytokines from the common gamma chain receptor family, such as IL-15, IL-21 and IL-7, show promise for cancer immunotherapy and have been incorporated individually into the immunocytokine approach.However, their efficacy as monotherapy is limited.Here, we investigated the molecular design of tumor-directed trifunctional antibody-cytokine fusion pro
