| abstract |
The present invention relates to anti-human PD-L2 antibodies, or the antigen binding parts thereof, which specifically bind human PD-L2 such that PD-L2 binding to PD-1 is blocked, wherein preferably said antibodies or antigen binding parts do not bind to mouse PD-L2 and human PD-L1 but bind to cyno PD-L2, preferably as determined by FACS analysis. The present invention also relates to nucleotide sequences encoding the anti-human PD-L2 antibodies, vectors and cells containing the nucleotide sequences. The antibodies and/or compositions of the invention are useful in human therapy, e.g., cancer therapy, and/or in cell-line based bioassays for determining T cell signalling. |
