The emerging heterogeneity of dendritic cells (DCs) mirrors their increasingly recognized division of labor at myriad control points in innate and acquired cellular immunity. We separately generated blood monocyte-derived DCs (moDCs), as well as Langerhans cells (LCs) and dermal-interstitial DCs (DDC-IDCs) from CD34(+) hematopoietic progenitor cells.(More)
Dendritic cells are potent antigen-presenting cells for several primary immune responses and therefore provide an opportunity for evaluating the amounts of cell-associated antigens that are required for inducing T cell-mediated immunity. Because dendritic cells express very high levels of major histocompatibility complex (MHC) class II products, it has been(More)
Human blood dendritic cells require UV-B radiation (290 to 320 nm) in excess of 1,000 J/m2 to inhibit their stimulation of primary T-cell responses to alloantigen by 60% to 70% or more. The effect is twofold to threefold greater in the allogeneic mixed leukocyte reaction (MLR) than in polyclonal mitogenesis using comparable numbers of dendritic cells and(More)
A retrospective analysis of the outcome for 283 haematological patients who relapsed after high dose chemotherapy and autologous stem cell transplantation during a five year period from 1989 to 1994 is presented. The patients were treated in accordance with local regimes at 20 Nordic transplantation centers and included patients with acute leukemia (157(More)
