PD-1 signaling pathway

NP-12 TFA displays equipotent antagonism toward PD-L1 and PD-L2 in rescue of lymphocyte proliferation and effector functions .
NP-12 TFA rescues the proliferation in the mouse splenocyte assay system with average EC50 values of 17 nM and 16.6 nM against rmPD-L1 and rmPD-L2 respectively .
NP-12 TFA is also able to significantly rescue recombinant human PD-L1 and PD-L2 mediated inhibition of in vitro human PBMC proliferation, with average EC50 values of 63.3 nM and 44.1 nM against PD-L1 and PD-L2 respectively .
has not independently confirmed the accuracy of these methods. They are for reference only.
