FLASH Irradiation Modulates Immune Responses and Accelerates Lung Recovery: A Single‐Cell Perspective

open access: yesAdvanced Science, EarlyView.
Single‐cell RNA sequencing reveals distinct immune responses to FLASH versus conventional dose rate irradiation in early radiation‐induced lung injury. FLASH irradiation reduces Ccrl2⁺ neutrophil infiltration, activates CD4⁺ CD40L⁺ Th cells, restrains pro‐inflammatory Mefv⁺ monocytes, and enhances epithelial repair via TGF‐β signaling, underscoring its

PIEZO1‐GPX4 Axis Mediates Mechanical Stress‐Induced Vertebral Growth Plate Dysplasia via Ferroptosis Activation

open access: yesAdvanced Science, EarlyView.
Mechanical stress activates PIEZO1 in vertebral growth plate chondrocytes, triggering ferroptosis through direct binding and inhibition of GPX4. This axis promotes lipid peroxidation and pathological ossification, accelerating spinal deformities. Clinical and genetic evidence (Piezo1‐cKO) confirms its role in scoliosis progression.
