Tumour-initiating cells capable of self-renewal and differentiation, which are responsible for tumour growth, have been identified in human haematological malignancies and solid cancers. If such minority populations are associated with tumour progression in human patients, specific targeting of tumour-initiating cells could be a strategy to eradicate(More)
Protective T-cell memory has long been thought to reside in blood and lymph nodes, but recently the concept of immune memory in peripheral tissues mediated by resident memory T (T(RM)) cells has been proposed. Here we show in mice that localized vaccinia virus (VACV) skin infection generates long-lived non-recirculating CD8(+) skin T(RM) cells that reside(More)
Chemotactic factors are postulated to direct emigration of lymphocytes from the blood stream into sites of inflammation. Members of a family of chemotactic cytokines, termed chemokines, have been shown to attract lymphocytes but efficacy, i.e., the maximal percentage of attracted cells, has been low. We have identified a highly efficacious lymphocyte(More)
BACKGROUND Neonatal-onset multisystem inflammatory disease is characterized by fever, urticarial rash, aseptic meningitis, deforming arthropathy, hearing loss, and mental retardation. Many patients have mutations in the cold-induced autoinflammatory syndrome 1 (CIAS1) gene, encoding cryopyrin, a protein that regulates inflammation. METHODS We selected 18(More)
T cells play a pathogenic role in many inflammatory and certain malignant skin diseases, including psoriasis, atopic and allergic contact dermatitis, and cutaneous T-cell lymphoma. Memory T cells that infiltrate the skin express a unique skin-homing receptor called cutaneous lymphocyte-associated antigen (CLA), a carbohydrate epitope that facilitates the(More)
CD4+CD25+ T regulatory cells (Treg) are thought to be important in the peripheral tolerance. Recent evidence suggests that human peripheral blood CD4+CD25+ T cells are heterogeneous and contain both CD4+CD25(high) T cells with potent regulatory activity and many more CD4+CD25(low/med) nonregulatory T cells. In this study, we found that virtually all(More)
The kinetics of rolling and transient adhesions through selectins may depend on the kinetics and mechanical properties of the selectin:ligand bond, as well as on cellular properties including receptor-anchoring to the cell membrane and cytoskeleton. Kinetics are known to depend on the selectin and may also be ligand dependent. Here, we study the kinetics of(More)
We demonstrate an additional step and a positive feedback loop in leukocyte accumulation on inflamed endothelium. Leukocytes in shear flow bind to adherent leukocytes through L-selectin/ligand interactions and subsequently bind downstream and roll on inflamed endothelium, purified E-selectin, P-selectin, L-selectin, VCAM-1, or peripheral node addressin.(More)
Chemokines are critical molecules in leukocyte trafficking, promoting site-specific migration to various tissues. The chemokine receptor CCR4 has recently been associated with skin-homing T cells. In view of the potential importance of CCR4 in skin homing of T cells, we investigated the expression pattern of CCR4 and its ligands TARC/CCL17 and MDC/CCL22 in(More)
