TPP-1 is a potent inhibitor of the?PD-1/PD-L1 interaction. TPP-1 binds specifically to PD-L1 with a high affinity (KD=95 nM). TPP-1 inhibits human tumor growth in vivo via reactivating T-cell function[1]. | [in vivo]
TPP-1 (subcutaneous injection; 4 mg/kg; every other day eight times; 32 days) inhibits tumor growth (compared with SPP-1 and control). The growth rate in TPP-1-treated mice is 56%. And when administered in the absence of T cells (control group), TPP-1 has no effect on the growth of the H460-luc tumors[1]. | Animal Model: | 5 to 6-week-old female Balb/c nude mice? injected with H460 cells transfected with the plvx-puro/luciferase lentiviral vector[1] | | Dosage: | 4 mg/kg | | Administration: | Subcutaneous injection; 4 mg/kg; every other day eight times; 32days | | Result: | Inhibited the tumor growth in a tumor xenograft model via reactivating T-cell function.? |
