| Outline of Final Research Achievements |
Tumor bearing mice were treated with anti PD-L1 Ab and/or OK-432, and the mechanism of antitumoe effect was analyzed.PD-L1 was not expressed on untreated SCCVII cells, but after adding IFN-γ, PD-L1 was expressed. anti PD-L1 Ab couldn't demonstrated directly effective on SCCVII proliferation (MTT assay). Combination therapy anti PD-L1 Ab and OK-432 inhibited tumor growth of SCCVII bearing mice.
It was suggested that combination therapy anti PD-L1 Ab and OK-432 could be an effective therapy against oral cancer.
