A CD8 T Cell Infiltration-Driven Prognostic Signature for Gastric Cancer: Bridging Tumor Immunity and Clinical Outcomes.

CD8 T cells play pivotal roles in antitumor immunity, where infiltration levels often correlate with favorable prognosis. However, the functional heterogeneity of CD8 T cell subsets within the gastric cancer (GC) tumor microenvironment (TME)-particularly their divergent impacts on tumor progression, immunotherapy response, and clinical outcomes-remains poorly characterized. We integrated single-cell RNA sequencing (scRNA-seq) data from 23 GC tissues (GEO: GSE150290) with bulk transcriptomic profiles from TCGA-STAD to dissect CD8 T cell heterogeneity.

Sevoflurane Preconditioning Protects Against Myocardial Ischemia Reperfusion Injury in Mice via PI3K/AKT/GSK3β-mediated Upregulation of Syntaxin1a.

Inhaled Pro-Efferocytic Nanozymes Promote Resolution of Acute Lung Injury.

Acute lung injury (ALI) is a significant contributor to the morbidity and mortality of sepsis. Characterized by uncontrolled inflammation and excessive inflammatory cells infiltration in lung, ALI has been exacerbated by impaired efferocytosis (clearance of apoptotic cells by macrophages). Through specific receptor recognition and activation of downstream signaling, efferocytic macrophages promote resolution of inflammation by efficiently engulfing dying cells, avoiding the consequent release of cellular inflammatory contents.
