IL17A and neoplasm: Finally, while it was previously shown in the B16‐cOVA model that dysfunctional OT‐I cells responding to this tumor do not develop into IL‐4‐ or IL‐10‐producing cells [14], we confirmed these findings for OT‐I cells responding to D5.1G4‐cOVA, and we found that OT‐I cells responding to both tumors also failed to acquire IL‐5‐, IL‐9, or IL‐17‐secreting functionality (data not shown).
