Differential and regionally distinct molecular responses distinguish FLASH and conventional RT in a medulloblastoma model while preserving therapeutic outcomes

Michèle Knol, Javier Franco‐Pérez, Aymeric Almeida…·Paola Ballesteros‐Zebadúa

Hypo-fractionated FLASH and conventional radiotherapy (3x10 Gy) each ablated orthotopic human medulloblastoma in nude mice; FLASH evoked distinct microglial and hippocampal transcriptional programs and less neuroinflammation.

Neuroprotection following FLASH-RT may be mediated by sustained glutamate receptor AMPAR activation in CA3 neurons

Louis V. Kunz, Aymeric Almeida, Michèle Knol…·Marie‐Catherine Vozenin

This study investigates FLASH-RT's neuroprotective effects by showing sustained AMPAR activation in CA3 neurons through early transcriptional upregulation of glutamate receptor genes.

Differentiating unirradiated mice from those exposed to conventional or FLASH radiotherapy using MRI

Jeannette Jansen, Adam Kimbler, Olivia G.G. Drayson…·Paola Ballesteros‐Zebadúa

This study uses MRI to differentiate between unirradiated mice and those exposed to conventional or FLASH radiotherapy, finding distinct brain changes after conventional but not FLASH treatment.
