An updated review of gastrointestinal toxicity induced by PD-1 inhibitors: from mechanisms to management

Frontiers in Immunology, 2023
PD-1 inhibitors, as one of commonly used immune checkpoint inhibitors, enable T-cell activation and prevent immune escape by blocking the PD-1/PD-L1 signaling pathway.

Use of Biomarkers of Inflammation in the Differentiation of Iron Deficiency and Anaemia—Lessons from Inflammatory Bowel Disease

Diagnostics
Iron deficiency and iron deficiency anaemia are common in inflammatory bowel disease (IBD), to the detriment of the patients’ quality of life. Since ferritin, as an acute-phase protein (APP), has limited diagnostic value in IBD, concurrent assessment of ...

Spleen‐Targeting Biomimetic Hybrid Nanocarriers for Systemic Immune Reprogramming in Colitis: RBC Membrane Vesicle‐Fused Lipid Nanoparticles

Advanced Functional Materials, EarlyView.
A spleen‐targeting hybrid nanoplatform (RBCMV‐LNP‐RP) harnessing erythrophagocytosis mimics senescent red blood cell clearance to achieve spleen‐specific delivery of rapamycin. This biomimetic system enables selective accumulation in splenic macrophages, orchestrating systemic immune reprogramming and promoting mucosal healing in an inflammatory bowel ...

Germanane Quantum Dots Promote Metabolic Reprogramming of Immune Cells Toward Regulatory T Cells and Suppress Inflammation In Vitro and In Vivo

Advanced Functional Materials, EarlyView.
Metabolic changes in immune cells direct the phenotype and function of the host immune system. Smart nanomaterials must target metabolic pathways to direct immune cell fate. This study reports the fabrication and first application of germanane quantum dots (GeHQDs) to modulate inflammation in vitro and in vivo.
