Spatial immune programs associated with nodal status differ between lymphoid follicular regions and peritumoral tonsillar tissue in HPV-positive oropharyngeal cancer

IntroductionIn human papillomavirus (HPV)-positive oropharyngeal cancer (OPC), lymph node metastasis is common, yet its biological and prognostic implications remain incompletely understood. Less is known about the spatial organization of immune progra…

Data-augmented machine learning refines the effective-concentration estimate for eculizumab in complement-mediated diseases

Eculizumab, a humanized monoclonal antibody targeting the complement protein C5, is highly efficient in paroxysmal nocturnal hemoglobinuria, atypical hemolytic uremic syndrome, generalized myasthenia gravis, and neuromyelitis optica spectrum disorder. …

Tumoral immune microenvironment profiling in B-cell non-Hodgkin lymphoma stratifies patients in different prognostic groups

BackgroundNon-Hodgkin lymphomas (NHL) represent a heterogeneous group of B-cell-derived malignancies. Previous studies showed that tumor immune microenvironment (TIM) components are associated with tumor development and progression. Furthermore, recent…

Post-transplant anti-thymocyte globulin exposure predicts graft-versus-host disease and donor chimerism outcomes in reduced intensity conditioning allogeneic stem cell transplantation

Although anti-thymocyte globulin (ATG) is commonly used as prophylaxis against graft-versus-host disease (GVHD) following allogeneic haematopoietic stem cell transplantation (alloSCT), there is considerable inter-patient variability in ATG exposure. Th…

Reduced IgM natural autoantibody levels against heat shock proteins are associated with disease severity in juvenile idiopathic arthritis

IntroductionNatural autoantibodies (nAAbs) contribute to immune homeostasis and may be altered in patients with autoimmune diseases. While anti-heat shock protein (Hsp) antibodies have been previously described in juvenile idiopathic arthritis (JIA), t…

Gut microbiota derived indoles are altered and associate with immune activation in moderate and severe carotid stenosis

BackgroundAn imbalance of gut microbiota, their metabolites as well as inflammatory mediators have been increasingly linked to both atherosclerosis and stroke. However, data on microbiota derived tryptophan and histidine metabolites in carotid atherosc…

Identification, characterization, and expansion of innate lymphoid cells derived from canine peripheral blood mononuclear cells

Innate lymphoid cells (ILCs), a family of innate immune cells of lymphoid origin, serve as first responders to tissue damage and inflammation. They play a crucial role in defending mammals against tumor growth. ILCs can migrate between organs, move wit…

Low-dose multi-walled carbon nanotubes are non-inflammatory alone but amplify lipopolysaccharide-induced cytokine responses in A549 lung epithelial spheroids

BackgroundAirborne pollutants comprise biological agents such as lipopolysaccharide (LPS) and engineered nanomaterials, including carbon nanotubes (CNTs), which are increasingly prevalent in industrial and consumer applications. Although the pulmonary …
