Uptake of Leishmania major by dendritic cells (DCs) results in activation and interleukin (IL)-12 release. Infected DCs efficiently stimulate CD4- and CD8- T cells and vaccinate against leishmaniasis. In contrast, complement receptor 3-dependent phagocytosis of L. major by macrophages (MPhi) leads exclusively to MHC class II-restricted antigen presentation(More)
Protection against Leishmania major in resistant C57BL/6 mice is mediated by Th1 cells, whereas susceptibility in BALB/c mice is the result of Th2 development. IL-12 release by L. major-infected dendritic cells (DC) is critically involved in differentiation of Th1 cells. Previously, we reported that strain differences in the production of DC-derived(More)
The PI3K pathway plays a pivotal role in the stimulation of mast cells. PI3K-dependent kinases include the serum- and glucocorticoid-inducible kinase 1 (SGK1). The present study explored the role of SGK1 in mast cell function. Mast cells were isolated from bone marrow (BMMC) of SGK1 knockout mice (sgk1(-/-)) and their wild-type littermates (sgk1(+/+)). The(More)
Mast cells (MC) are key mediators of the immune system, most prominently known for their role in eliciting harmful allergic reactions. Mast cell mediator release (e.g. by degranulation) is triggered by FcεRI recognition of antigen - IgE complexes. Until today no therapeutic targeting of this and other mast cell activation pathways is established. Among(More)
445 Letters to the Editor Sir, Extracorporeal photopheresis (ECP) is described as effective and safe in the treatment of erythrodermic cu-taneous T-cell lymphoma (CTCL) (1). It is thought that ECP acts mainly through the induction of apoptotic cell death in leukocytes; this apoptotic cell death may cause subclinical immunosuppression. Actinically derived(More)
