Splet14. apr. 2024 · Abstract. KN052 is a recombinant PDL1/OX40 bispecific antibody which can block PDL1 and PD1/CD80 pathway and active the OX40 signal pathway at the same time. Inhibited PDL1 can block cancer cells to evade T-cell-mediated immune responses and restores T-cell activation and antitumor responses. On the other hand, biding to OX40 … SpletAbrogation of PDL1 expression or antibody-mediated PDL1 blockade strongly sensitized cancer cells to IFN cytotoxicity through a STAT3/caspase-7-dependent pathway. Moreover, somatic mutations found in human carcinomas within these PDL1 sequence motifs disrupted motif regulation, resulting in PDL1 molecules with enhanced protective …
