Agent‐Based Simulations of Lung Tumor Evolution Suggest That Ongoing Cell Competition Drives Realistic Clonal Expansions

Advanced Science, EarlyView.
Computational simulations of tumor evolution are increasingly used to infer the rules underlying cancer growth, with the goal of one day recommending tailored treatments. Here we show that the properties of lung cancer sequencing data are best replicated by a model which assumes that cells compete both to proliferate and survive. ABSTRACT Computational

A Personalized Haplotype‐Resolved Near‐Gapless Genome Framework for Somatic Variant Discovery in Hepatocellular Carcinoma

Advanced Science, EarlyView.
A patient‐specific, haplotype‐resolved genome framework improves detection and interpretation of somatic variants in hepatocellular carcinoma. Using multi‐platform sequencing, the personalized assembly resolves complex regions including centromeres and MHC/HLA loci, enhances structural variant discovery, and links regulatory alterations to allele ...

B Cells are Activated via a Nanoporous Interface that Stabilizes Microvilli and Engages Mechanosensitive Ion Channels

Advanced Science, EarlyView.
B cells can be activated independently of antigen recognition via mechanical stimulation through nanoporous substrates. Exposure to such substrates induced B cell microvilli extension into the pores, intracellular Ca2+ signaling, phosphorylation of signaling proteins, and CD69 expression.

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.

Copper‐Doped Prussian Blue Nanozymes With Hyaluronic Acid‐Mediated Targeting Alleviate Oxidative Stress and Regulate Cholesterol Handling for Atherosclerosis Therapy

Advanced Science, EarlyView.
CuPB@HA is a CD44‐associated, plaque‐targeted nanozyme that alleviates oxidative stress, inflammation, and lipid accumulation in macrophages. By reducing CD36‐dependent lipid uptake and promoting ABCA1/ABCG1‐mediated cholesterol handling, it improves macrophage function, preferentially accumulates in atherosclerotic lesions, reduces plaque burden, and ...

Clinical Significance of PD‐L1 and HLA Expression in Esophageal Squamous Cell Carcinoma in Response to Immunotherapy

Annals of Gastroenterological Surgery, EarlyView.
This study evaluated immune‐related biomarkers in esophageal squamous cell carcinoma treated with immune checkpoint inhibitors after postoperative recurrence. PD‐L1 expression in tumor‐associated macrophages and tumor cells, together with HLA class I downregulation and HLA‐DR expression, were associated with favorable responses to immunotherapy.

Longitudinal tracking of T-cell repertoire reveals long-lasting CD4⁺ yellow fever specific clone cluster

Инфекция и иммунитет
Infection is inconceivable without T cells. T cells not only eliminate virus-infected cells and participate in the formation of immunological memory, but also indirectly modulate the humoral response through the selection and maintenance of specific B ...

Machine Learning‐Enhanced Random Matrix Theory Design for Human Immunodeficiency Virus Vaccine Development

Advanced Intelligent Discovery, EarlyView.
This study integrates random matrix theory (RMT) and principal component analysis (PCA) to improve the identification of correlated regions in HIV protein sequences for vaccine design. PCA validation enhances the reliability of RMT‐derived correlations, particularly in small‐sample, high‐dimensional datasets, enabling more accurate detection of ...
