Loss of NR2F6 Protects from Salmonella Typhimurium Infection

Advanced Science, EarlyView.
Loss of nuclear receptor NR2F6 reduces tissue‐resident macrophage populations. Nr2f6‐deficient mice are protected from weight loss and bacterial load during infection with Salmonella Typhimurium. Pro‐inflammatory cytokines and iron levels are altered in infected Nr2f6‐deficient mice.

Irisin‐Loaded Cerium‐Containing Mesoporous Bioactive Glass for Effective Immunomodulation and Odontogenesis of Dental Pulp Cells

Advanced Science, EarlyView.
The Irisin/Ce‐MBGNs delivery system can slowly release myokine Irisin for vital pulp therapy. Irisin/Ce‐MBGNs can enhance mitochondrial function and promote the differentiation of inflammatory macrophages toward M2‐Mφ, thereby regulating the immune response mechanism of inflamed dental pulp.

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

Advanced 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
