T lymphocytes. Besides, RNA-seq data reveals losartan impedes JAK2/STAT1 signaling activation upon irradiation, suppresses the interferon-related DNA damage resistant signature (IRDS) expression and diminishes the immune suppressive factors PD-L1 and IDO induced by irradiation in TNBC cells. Collectively, in our study, we investigate the role of losartan in radiosensitization and demonstrate losartan could reverse the immunosuppressive TME induced by RT in TNBC, which suggests that losartan combined with RT may represent a promising strategy for the treatment of TNBC.
