Abstract
Deciphering mechanisms for cancer immune escape may provide targets for improving immunotherapy efficacy. By in vivo genome-wide CRISPR loss-of-function screening in a mouse model of triple negative breast cancer (TNBC), we uncovered a non-classical function of Cd28 in cancer cells to promote immune escape. Knocking out Cd28 in cancer cells increased infiltration of type I conventional DC (cDC1) and activated tumor-specific CD8
