Interestingly, BAY1834942 when used in tumor cell/T-cell co-culture systems increased the production of T-cell cytokines and effector molecules (e.g., IFN-γ, TNFα, IL-2, granzyme B) and resulted in improved tumor cell killing, which indicates that this antibody may be a novel immune checkpoint inhibitor [26]. This evidence concerns the gene IL2 and neoplasm.
