Proton FLASH radiotherapy enhances control of triple-negative breast cancer through STING-IRF3 and CD8+ T-cell immunity

Pierre Loap, Ioannis Paraskevaidis, Cezara Cheptea…·Ioannis I. Verginadis

This study shows that FLASH proton radiotherapy enhances antitumor immunity and tumor control in triple-negative breast cancer by activating STING-IRF3 pathways and CD8+ T-cell responses.

Fractionated proton and photon FLASH irradiation mitigates radiation-induced lymphopenia through kinetic sparing of circulating lymphocytes

Cezara Cheptea, Pierre Loap, Andrew Friberg…·Ioannis I. Verginadis

This study shows FLASH irradiation reduces radiation-induced lymphopenia in mice by sparing circulating lymphocytes, with durable CD8 T cell preservation across proton and photon modalities.
