Opposing Two-Fraction Regimens Combining Low and High Doses of Ionizing Radiation Elicit Differential Immune Responses

Key Points

• This research aims to explore how different sequences of radiation doses influence immune responses, particularly in the context of immunotherapy.
• Examined low and high doses of ionizing radiation
• Analyzed immune responses elicited by varying fractionation regimens
• Considered the timing and sequence of radiation delivery
• Opposing dose sequences resulted in varied immune responses
• Specific fractionation schemes enhanced immunologic markers
• Findings indicate a need for tailored radiation-immunotherapy combinations
