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 …

Reorganization and functional divergence of the CD4+ memory T cell compartment in hidradenitis suppurativa

Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease with poorly understood and complex pathophysiology with interplay between many immune and stromal cells. While the T cell infiltrate in HS is well-documented, the relationship between…

Developmental expression of immune-associated secreted novel AID/APOBEC-like deaminases (SNAD1s) in common carp (Cyprinus carpio)

Early developmental stages of teleost fish represent vulnerable phases of the life cycle, characterized by exposure to fluctuating abiotic and biotic environmental conditions. Immune system maturation is gradual, beginning with reliance on maternally t…

TP53 loss attenuates C1q-associated macrophage remodeling in early adenomatous polyps in a porcine FAP model

BackgroundFamilial adenomatous polyposis (FAP) is a hereditary condition that almost invariably leads to colorectal cancer. While TP53 inactivation is well established as a late event in the adenoma-to-carcinoma sequence, its functional role during the…
