| Chimeric Use Statement: | This is a bispecific anti-mouse antibody created by fusing anti-PDL-1 VHH domains to the C-terminus of the heavy chains of the anti-mouse CTLA-4 antibody clone 9D9 in a mouse IgG1 D265A format. The mouse IgG1 D265A format is an Fc-silenced format, reducin |
| Specificity Statement: | The antibody is specific for CTLA-4. |
| Application Notes: | The antibody has been used to block CTLA-4 and has been shown to enhance T-cell immunity against tumours (Quezada et al, 2006). 9D9 also has an anti-B16/BL6 melanoma effect in non-irradiated tumour-bearing recipients when given as combinatorial therapy with Gvax (Peggs et al, 2009). Selby et al. (PMID: 24777248) show how conversion of the original mouse IgG2b to a mouse IgG2a greatly increases anti-tumor activity of the 9D9 antibody in both MC38 (C57BL/6 mice) and CT26 (BALB/c mice) models. This mechanism both involves blockade of CTLA4 as well as depletion of tumor-infiltrating regulatory T-cells. Fc Silent antibodies were shown to have reduced anti-tumor activity as they did not deplete tumor infiltrating regulatory T-cells, however they lead to expansion of peripheral Tregs. |
