Comparative prognostic analysis of allogeneic hematopoietic stem cell transplantation regimens in the treatment of severe aplastic anemia

BackgroundSevere aplastic anemia (SAA) is a fatal bone marrow failure disorder. Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is the definitive curative treatment for SAA. This study evaluated the prognosis of patients with severe apla…

IL18BP links antigen processing and presentation programs to a dendritic cell-enriched immunoregulatory state in colorectal cancer

BackgroundAntigen processing and presentation (APP) is required for tumor immune recognition, but its relationship with the immune landscape in colorectal cancer (CRC) remains incompletely defined. In this study, APP-related transcriptional programs we…

Effect of immunosuppressive drugs on glucose-stimulated insulin secretion: concentration-response studies in dynamic perifusion assays

Immunosuppressive drugs, which are required to maintain graft function in transplant recipients, are associated with many unavoidable side effects including posttransplant diabetes mellitus (PTDM) that involves both peripheral insulin resistance and im…

Comparative profiling of MAIT cells across gastrointestinal cancers identifies conserved NK receptor dysregulation and HCC-specific defects in cytotoxicity and XBP1s signaling

Background & aimsMucosal-associated invariant T (MAIT) cells are innate-like T lymphocytes with cytotoxic capacity and emerging roles in tumour immunity. While MAIT cells express a diverse repertoire of natural killer (NK) receptors, the functional sig…

Integrative multi-omics analysis reveals a membrane tension signature associated with tumor-stroma crosstalk in hepatocellular carcinoma

BackgroundDysregulated membrane tension (MT) drives tumor cell migration, invasion, and immune evasion, yet the prognostic value of MT-related genes (MTRGs) in hepatocellular carcinoma (HCC) remains unclear.MethodsWe integrated transcriptomic and clini…

Supernatants from stored platelet concentrates modulate the inflammatory response in platelet-depleted blood ex vivo

IntroductionPlatelets contain a wide range of bioactive mediators, many of which accumulate during storage of platelet concentrates and have immunomodulatory properties. Our objective was to investigate how mediators derived from stored platelet concen…

Histidine alleviates copper-induced intestinal inflammation through oxidative stress-mediated mitochondrial damage and the Hif1α-Tnfα/Il1β pathway

IntroductionCopper (Cu) is an essential trace element for vertebrates, but excessive intake can induce intestinal toxicity. Whether nutritional intervention can alleviate Cu overload-induced intestinal damage and the underlying mechanisms remain unclea…

Extracellular vesicle phenotypic patterns associated with CMV, EBV and HHV-6 reactivation after haploidentical transplantation with post-transplant cyclophosphamide

IntroductionHuman cytomegalovirus (CMV), Epstein–Barr virus (EBV), and human herpesvirus 6 (HHV-6) remain important causes of morbidity after allogeneic hematopoietic cell transplantation (HCT), yet biomarkers predicting viral reactivation are lacking….
