Antibody framework engineering enables augmented cytokine receptor signaling capacities of bispecific single domain antibody-based IL-21 mimetics

In this work, we developed bispecific antibody (bsAb)-derived surrogate agonists which mimic the function of IL-21 by targeting the IL-21 receptor composed of IL-21 R (CD360) and IL-2 Rγ (CD132). For this, antigen-specific VHHs (variable domains of the heavy chain of heavy-chain-...
