    Notes: Summary The relationship between Epstein-Barr virus (EBV) and the host is profoundly disturbed by allogeneic bone marrow transplantation (BMT) because EBV resides in the recipient's hematopoietic system, which has to be destroyed in the majority of cases, and in the donor's hematopoietic system, i.e., the marrow graft. We have shown that EBV may be eradicated from some BMT recipients and that the virus may be transferred with the marrow graft. During the immediate post-transplant period oropharyngeal EBV excretion may occur which, by infecting passing B lymphocytes, may act as co-factor for acute graft-versus-host disease and help the virus to survive, despite the temporary depletion of its reservoir. The coexistence of totally different EBV strains in BMT recipients but not in healthy, untransfused controls, suggests that superinfection may by possible in case of immunodeficiency; alternatively, transfer of the virus by the reservoir itself (the B lymphocytes) might be the only effective route for superinfection. The generation of ‘variant’ strains during viral replication may form the basis of the vast polymorphism between wild-type EBV isolates in the population.

    Description / Table of Contents: Zusammenfassung Schon vor einigen Jahrzehnten haben Tierversuche gezeigt, daß zwischen Mäusen aus Inzuchtstämmen, die völlig identische Erbeigenschaften aufweisen, Transplantate problemlos akzeptiert werden, während Transplantate zwischen Individuen genetisch verschiedener Stämme nach einigen Tagen abgestoßen werden. Es konnte dann erwiesen werden, daß auch beim Menschen Erbfaktoren für Annahme oder Abstoßung von Fremdtransplantaten verantwortlich sind. Diese Erbfaktoren, heute HLA-System genannt, liegen auf dem sechsten Chromosom. Methoden wurden entwickelt, mit Hilfe von Antikörpern aus dem Blutserum schwangerer Frauen die ererbten HLA-Antigene zu bestimmen. Diese Bestimmung spielt heute eine große Rolle bei der Vorbereitung von Organverpflanzungen, besonders bei der Nierentransplantation, denn je besser die Übereinstimmung der HLA-Antigene zwischen Spender und Empfänger, um so größer sind die Chancen einer erfolgreichen Transplantation. Darüber hinaus gibt es in jüngster Zeit immer mehr Hinweise darauf, daß die HLA-Antigene gekoppelt oder sogar teilweise identisch sind mit den Immun-Response-Gen-Produkten, die bestimmen ob ein Organismus gut oder weniger gut in der Lage ist, eine Immunität gegen infektiöse Bakterien oder Viren zu entwickeln. Schließlich scheinen auch Zusammenhänge zu bestehen zwischen der Existenz ganz bestimmter HLA-Antigene und der Prädisposition zu Krankheiten, etwa der Gluten-Enteropathie, der Myasthenia gravis, der Multiplen Sklerose, des Diabetes mellitus, und viele anderen.
    Notes: Summary Some decades ago, animal experiments have shown that inbred mice with completely identical genetic characteristics accept transplants between each other without any problem while transplants between individuals of genetically different strains are being rejected after a few days. It was also proven later that with men, genetical factors are responsible for acceptance or rejection of homologous transplants. These genetic factors, although they are called the HLA system, are located on the sixth chromosome. Methods were developed to determine the inherited HLA antigens with the help of antibodies present in the blood serum of pregnant women. This determination is of great importance in preparing transplants organ, especially of kidneys, because chances of successful transplantation are the greater, the better the correspondence of HLA antigens between donor and recipient. Furthermore, there exists growing indication that HLA antigens are coupled or even partly identical with the immune response gene products. These determine whether an individual is more or less suited to develop an immunity against bacterial or viral infections. Finally, there subsist associations of certain HLA antigens and diseases such as gluten enteropathy, myasthenia gravis, multiple sclerosis, diabetes mellitus and many others.
