To investigate human natural killer (NK)-cell reactivity in vivo we have reconstituted human immune system components by transplantation of human hematopoietic progenitor cells into NOD-scid IL2Rγ(null) mice. We demonstrate here that this model allows the development of all NK-cell subsets that are also found in human adult peripheral and cord blood,(More)
Epstein-Barr virus (EBV) persistently infects more than 90% of the human population and is etiologically linked to several B cell malignancies, including Burkitt lymphoma (BL), Hodgkin lymphoma (HL), and diffuse large B cell lymphoma (DLBCL). Despite its growth transforming properties, most immune-competent individuals control EBV infection throughout their(More)
Many pathogens relevant to human disease do not infect other animal species. Therefore, animal models that reconstitute or harbor human tissues are explored as hosts for these. In this review, we will summarize recent advances to utilize mice with human immune system components, reconstituted from hematopoietic progenitor cells in vivo. Such mice can be(More)
Mutations in genes involved in macroautophagy have been found to be associated with Morbus Crohn, also called Crohn's disease (CD), an inflammatory bowel disease. Taking this disease as an example for pathogenesis due to altered macroautophagy, we discuss here how macroautophagy supports innate and adaptive immunity. This support ranges from maintenance of(More)
