Tumor mutation burden, immune checkpoint crosstalk and radiosensitivity in single-cell RNA sequencing data of breast cancer.

CONCLUSIONS: RR cells exhibited a basal subtype, high PD-L1 expression, and high TMB with mutational signature found in tumors having MSI. Differential crosstalk between tumor and immune cells was associated with the patient subtype of breast cancer. These findings could be useful to identify potential biomarker(s) and optimal combination strategies of immune checkpoint blockades and radiation therapy in the management of breast cancer.
