Variant signaling topology at the cancer cell–T-cell interface induced by a two-component T-cell engager

     

摘要

Bispecific T-cell-engaging antibodies(BiTEs)convey antigenic information from cancer to the T-lymphocyte-associated CD3 complex,thus redirecting immune effector cells to induce target cell lysis.Since antigenic information from transformed tissues is rarely unambiguous,we recently introduced novel T-cell-engaging antibody fragments called hemibodies for the combinatorial,ultraprecise targeting of cancer.1 Here,we report the unprecedented enhancement of the plasticity of immunological synapse(IS)formation and variant signaling topology at the cancer cell–T-cell interface induced by hemibodies compared to that induced by BiTEs.
