Targeting inhibitory phagocytosis checkpoints in cancer immunotherapy: mechanisms, therapeutic strategies, and translational challenges

Tumors evade macrophage-mediated clearance through mechanistically distinct but functionally convergent anti-phagocytic pathways. This review examines canonical and emerging receptor–ligand “don’t eat me” axes, Siglec-dependent glyco-inhibitory checkpo…

Adipose-derived mesenchymal stem cell-exosomes attenuate lipopolysaccharide-induced acute lung injury in mice by regulating the TGFBR2/Smad4 axis to suppress NLRP3-mediated macrophage M1 polarization and pyroptosis

ObjectiveThis study investigated whether adipose-derived mesenchymal stem cells-exosomes (ADMSC-Exo) alleviate lipopolysaccharide (LPS)-induced acute lung injury (ALI) by regulating NLRP3 inflammasome-mediated macrophage M1 polarization and pyroptosis …

Biomimetic PD-1-MSCs membrane-engineered nanoparticles for enhanced blood-brain barrier penetration and anti- glioma therapy

ObjectiveGlioma is the most common and aggressive primary intracranial tumor. Its clinical management is substantially hindered by the blood–brain barrier (BBB) and the immunosuppressive tumor microenvironment (TME). This study aimed to construct PD-1-…

Camrelizumab-associated MG-like ocular neuromuscular toxicity after PD-1 inhibitor rechallenge in metastatic hepatocellular carcinoma: a case report with serial muscle injury-related biomarker changes

BackgroundImmune checkpoint inhibitors (ICIs) can cause rare but clinically important immune-related neuromuscular adverse events. Early warning signals for ICI-associated neuromuscular toxicity remain poorly defined, particularly after PD-1 inhibitor …
