Carnosic acid alleviates 5-Fluorouracil chemoresistance and enhances CD8+ T cell cytotoxicity in gastric cancer by regulating the CXCL12/CXCR7 axis

BackgroundKey features of gastric cancer (GC) include its aggressive nature, high metastatic capability, and a tendency for relapse. While 5-fluorouracil (5-FU) remains a cornerstone of GC treatment, its efficacy is substantially undermined by the emer…

Beyond histocompatibility: human leukocyte antigen as a cross-disciplinary platform for immune recognition and clinical decision-making

Human leukocyte antigen (HLA) molecules mediate peptide presentation and shape immune recognition, with clinical relevance well beyond donor-recipient matching. This review describes how HLA variation and anti-HLA immunity affect transfusion medicine, …

An endoplasmic reticulum stress- and Golgi apparatus-related signature reveals immune microenvironment remodeling and MUC16-driven PI3K/AKT activation in lung adenocarcinoma

BackgroundLung adenocarcinoma (LUAD), the most prevalent histological subtype of non-small cell lung cancer (NSCLC), is characterized by substantial clinical heterogeneity and a frequent propensity to acquire resistance to targeted therapies. Accumulat…

Assessing high-throughput surrogate assays for real-world HPV16- and HPV18-specific vaccine immune monitoring: a comparison of PBNA, cCLIA, and IgG

IntroductionSerological monitoring is needed for the real-world evaluation of immune responses after human papillomavirus (HPV) vaccination, but the pseudovirion-based neutralization assay (PBNA) is difficult to apply at scale.MethodsThis study compare…

Obesity and COVID-19 severity independently shape adipokine dysregulation and immune cell remodeling

BackgroundObesity is a major risk factor for severe COVID-19, yet the immunological mechanisms by which it modifies disease progression remain incompletely characterized. We aimed to dissect the independent and interactive contributions of obesity and …

Photodynamic therapy remodels cutaneous tumor immunity: innate priming, suppressive feedback, and translational opportunities

Photodynamic therapy (PDT) is an established local treatment for actinic keratoses, Bowen disease, and selected low-risk basal cell carcinomas, but its potential to reshape antitumor immunity may extend its value beyond direct phototoxicity. We conduct…

Increased interleukin-8 levels in cord blood serum of newborn—possible effect of cytokine dysregulation in pregnancies complicated by rheumatic disease on newborn vasculature

IntroductionSystemic autoimmune rheumatic diseases (SARDs) are associated with a higher risk of cardiovascular diseases. During pregnancy, maternal immune disbalance might impact the vasculature of the newborn. We, therefore, aimed to investigate a pos…
