Outline of Final Research Achievements |
In ovarian cancer clinical samples, the number of CD8-positive cells in cancer stroma was strongly correlated to PD-L1 expression on the tumor cells. In mouse models, depleting IFNGR1 resulted in lower level of PD-L1 expression in tumor cells, increased number of tumor-infiltrating lymphocytes, inhibition of tumor growth, and longer survival.
