Abstract Topical application of imiquimod (IMQ), a TLR7/8 ligand and potent immune activator, can induce exacerbate psoriasis, chronic inflammatory skin disorder. Recently, crucial role was proposed for the IL-23/IL-17 axis in psoriasis. We hypothesized that IMQ-induced dermatitis mice serve as model analysis pathogenic mechanisms psoriasis-like assessed its dependency. Daily IMQ on mouse back induced inflamed scaly lesions resembling plaque type These showed increased epidermal...

gp39, the ligand for CD40 expressed on activated CD4+ T helper cells, is required generation of antibody responses to T-dependent (TD) antigens. Treatment mice with anti-gp39 in vivo inhibits both primary and secondary formation TD, but not T-independent However, role this receptor-ligand pair development germinal centers B cell memory as yet undefined. Using an study examines requirement gp39-CD40 interactions induction center formation, well memory. Animals were immunized, treated...

Mesenchymal or stromal stem cells (MSC) interact with of the immune system in multiple ways. Modulation by MSC is believed to be a therapeutic option for autoimmune disease and transplant rejection. In recent years, B have moved into focus attention as targets treatment disorders. Current B-cell targeting based on indiscriminate depletion cells. The aim this study was examine whether human adipose tissue-derived (ASC) affect their proliferation, differentiation, function. ASC supported...

The development of microglia Microglia are the brain's immune cells, and they play important roles in health neurodegenerative disease. Kracht et al. performed single-cell analysis human microglial gene expression chromatin accessibility compared results with those other studies mice development. By using situ validation, these data identify fetal subsets that appear to be distinct from adult microglia, suggesting functional differences between developing mature brain.

Abstract We investigated the role of gp39-CD40 interaction in development glomerulonephritis lupus mice. In contrast to normal mice, mice had much higher percentages intensely gp39+ T cells their spleens even at preautoimmune age 1 mo, and further increase gp39 expression by anti-CD3 Ab stimulation was markedly greater cells. The pathogenic autoantibody-inducing ability Th clones splenic from could be blocked vitro anti-gp39 Ab. Acceleration nephritis transfer vivo also completely...

Multiple sclerosis lesion activity concurs with the extent of inflammation, demyelination and axonal suffering. Pro-inflammatory myeloid cells contribute to development, but self-limiting nature lesions implies as yet unidentified anti-inflammatory mechanisms. We addressed hypothesis that myelin ingestion by induces a foamy appearance confers function. First, we show myelin-containing foam in multiple consistently express series molecules while lacking pro-inflammatory cytokines. Second,...

Dendritic cells are thought to regulate tolerance induction vs immunization by transferring Ags and peripheral signals draining lymph nodes (LN). However, whether myelin Ag transfer presentation in LN occurs during demyelinating brain disease is unknown. In this study, we demonstrate redistribution of autoantigens from lesions cervical monkey experimental autoimmune encephalomyelitis (EAE) multiple sclerosis (MS). Immunohistochemical analysis revealed significantly more containing monkeys...

Although the existence of anti-inflammatory alternatively activated macrophages (aamphi) has been accepted widely based on in vitro studies, their vivo location, phenotype, and function still are debated. Gaucher disease (GD) is caused by a genetic deficiency lysosomal enzyme glucocerebrosidase characterized accumulation glycosphingolipids so-called cells (GCs). By using immunohistochemical analysis, we investigated whether this results an aamphi phenotype. GCs macrophage-like cells,...

This study was designed to investigate efficacy probiotic Lactobacillus rhamnosus GG delaying first onset pouchitis.Between 1989 and 2001, a consecutive series 127 presenting colitis underwent an at Erasmus Medical Center Rotterdam.

Primary infection with herpes simplex virus 1 (HSV-1) and varicella zoster (VZV) results in lifelong latent infections of neurons sensory ganglia such as the trigeminal (TG). It has been postulated that T cells retained TG inhibit reactivation virus. The acquisition specimens individuals within hours after death offered unique opportunity to characterize phenotype specificity TG-resident humans. High numbers activated CD8 + expressing a late effector memory were found reside latently...
