Ipilimumab 是全人类单克隆抗体 IgG1κ，能够抗 CTLA-4。其中CTLA-4是一种由活化的 T 细胞产生的免疫抑制分子。

Ipilimumab anti-CTLA-4) is an immunomodulatory monoclonal antibody directed against the cell surface antigen CTLA-4 and also a type of immune checkpoint inhibitor.

Objective: Ipilimumab augments antitumor activity of bispecific antibody-armed T cells. Concentrations: 0, 0.5, 5.0, and 50 μg/mL. Incubation Time: 10-14 days. Method: hPBMC were stimulated with anti-CD3 monoclonal antibody with or without ipilimumab and expanded for 10-14 days. ATC were harvested and armed with anti-CD3 x anti-EGFR BiAb (EGFRBi) or anti-CD3 x anti-CD20 BiAb (CD20Bi) to test for redirected cytotoxicity against COLO356/FG pancreatic cancer cell line or Burkitt's lymphoma cell line (Daudi).

Objective: To investigate whether Ipilimumab and PD-1 antibody enhance the ability of T cells to control the outgrowth of EBV-induced lymphomas. Formulation: PBS. Dosages: 100 μg, three times weekly
