GM‐CSF Promotes Neutrophil PD‐L1 Expression Through the VEGFR‐2/STAT6/CSF2 Signaling Axis in Oral Squamous Cell Carcinoma

Advanced Science, EarlyView.
VEGFR‐2 signaling in OSCC activates Src–STAT6‐dependent CSF2 transcription, driving tumor‐derived GM‐CSF secretion. GM‐CSF programs neutrophils to express PD‐L1 through STAT5–mTOR/S6K signaling, suppressing cytotoxic CD8+ T cells. This pathway reveals a tumor–neutrophil immune checkpoint circuit that limits anti‐PD‐1 responsiveness in OSCC.

Abnormal telomere shortening of peripheral blood mononuclear cells and granulocytes in patients with chronic idiopathic neutropenia

Haematologica, 2012
Background Chronic idiopathic neutropenia is characterized by immune-mediated suppression of neutrophil production. Because patients with immune-mediated bone marrow failure syndromes display age-inappropriate telomere shortening in leukocytes, we ...

Engineering Morphological Anisotropy to Control the In Vivo Transport Dynamics, Clearance, and Biodistribution of Silica Nanocarriers

Advanced Science, EarlyView.
Morphological anisotropy directs the in vivo transport under physiological flow and clearance of silica nanocarriers. Increasing anisotropy reduces cellular uptake, suppresses hepatic and splenic sequestration, and prolongs systemic circulation by steering particles toward the central flow core.

Engraftment of sheep splenic lymphocytes into NBSGW mice and application in Brucella infection

Animal Models and Experimental Medicine, EarlyView.
A sheep splenocyte‐reconstituted mouse model (Sh‐Spl mice) was established via intravenous injection of sheep splenic lymphocytes into immunodeficient mice to evaluate Brucella infection. Abstract Background The development of immune reconstituted xenograft mouse models has addressed the limitations imposed by interspecies immunological differences in ...

Age‐associated immune dysregulation links to disease severity in macrolide‐resistant Mycoplasma pneumoniae pneumonia: Insights from a comparative juvenile–adult mouse model

Animal Models and Experimental Medicine, EarlyView.
Macrolide‐resistant Mycoplasma pneumoniae (MRMP) infected both juvenile and adult mice, with results compared to normal juvenile mice. The findings revealed comparable bacterial loads between juvenile and adult mice, yet juvenile mice exhibited more severe lung damage and elevated levels of inflammatory cytokines.

From Marginal to Central: Marginal Zone‐like B Cells as Critical Targets in Cladribine‐Treated Multiple Sclerosis

Annals of Neurology, EarlyView.
Objective Multiple sclerosis (MS) is a chronic autoimmune disease where B cells play a central pathogenic role. Cladribine, an oral therapy, provides durable benefits by reshaping lymphocyte populations, yet its specific long‐term impact on distinct B‐cell subsets is not fully understood.

Safety and Feasibility of Magnetic Separation‐Based Blood Purification

Advanced NanoBiomed Research, EarlyView.
We present the preclinical biological safety and translational feasibility of a magnetic nanoparticle‐based extracorporeal blood purification platform for removal of disease‐causing blood factors. ISO 10993‐compliant studies and exaggerated worst‐case exposure models demonstrate efficient nanoparticle extraction (≥99.9%), favorable biocompatibility ...
