Kuper, C.F. (author), Ruehl-Fehlert, C. (author), Elmore, S.A. (author), Parker, G.A. (author)Cells of the immune system are found in every organ, from the classic lymphoid organs to tissues such as liver, mucosae, and omental adipose tissue. Toxicity to the immune system may be from a direct or indirect injury to lymphoid organs. The morphological responses range from lymphocyte depletion to proliferation, and may result in an increased...bookPart 2013

(author), TNO Kwaliteit van Leven (author)Children with Down syndrome (DS) have an increased risk for developing both acute myeloid as well as acute lymphoblastic leukemia. These leukemias differ in clinical characteristics and biology compared to leukemias in non-DS children. Moreover, children with DS have an increased risk of side-effects from cytostatic therapy, which complicates...article 2009

(author), TNO Kwaliteit van Leven (author), KvL (author)Specific IgE sera screening studies are employed to investigate protein cross-reactivity. Such nonfunctional immunochemical methods cannot measure the biological activity of proteins. Therefore, an assay using RBL cells transfected with human FcεRI was developed.

(author)Acute promyelocytic leukaemia (APL) is a disease that is distinguished from other leukaemias by the high potential for early haemorrhagic death. Several processes are involved, such as disseminated intravascular coagulation and hyperfibrinolysis.
