IFNB1 and neoplasm: However, mice with IFNβ-unresponsive TSA cells at the irradiated site mounted weaker tumour-specific CD8+ T cell responses and did not achieve long-term survival due to impaired ability to control the abscopal tumour, which either did not regress completely or recurred, while 43% of the mice with IFNAR1+ TSA cells at the irradiated site remained tumour-free for over 100 days (Fig. 2d-f).
