Allogeneic transplantation of peripheral blood progenitor cells (PBPC) makes the general anaesthesia of the donor unnecessary and may result in more rapid engraftment and faster recovery of the immune system. We have studied G-CSF-mediated PBPC mobilization in healthy donors and analysed the cellular composition of the resulting PBPC grafts. PBPC grafts(More)
Total immunoreactive insulin (IRI) is conventionally determined by radioimmunoassays. IRI measurement in rats can be made more sensitive, accurate, and practical, as demonstrated by a new modified enzyme-linked immunosorbent assay (ELISA). It is characterized by indirect binding of an anti-insulin antibody by an antiglobulin antibody and uses the principle(More)
In contrast to the success achieved with the production of hybridomas in the mouse system, creating human hybridomas is problematic. The reason is believed to be a lack of suitable malignant human cell lines. The work presented here demonstrates the establishment of three human parent cell lines--two of which are of T cell origin--by installing hypoxanthine(More)
Studies on subjective body odour ratings suggest that humans exhibit preferences for human leucocyte antigen (HLA)-dissimilar persons. However, with regard to the extreme polymorphism of the HLA gene loci, the behavioural impact of the proposed HLA-related attracting signals seems to be minimal. Furthermore, the role of HLA-related chemosignals in same- and(More)
The objective of this study was to investigate the expression of MHC antigens by retinal pigment epithelium cells (RPE) after stimulation with interferon-gamma (IFN-gamma) and to improve the currently practised technique of cadaver HLA typing. A concentration of 100 U/ml IFN-gamma induced expression of class I molecules up to greater than 90% 3 days after(More)
Monoclonal antibodies were raised against normal human bone marrow cells. One of the antibodies obtained, monoclonal antibody 3C4 (MA 3C4), the subject of this paper, was characterised by immunofluorescence studies with viable normal peripheral blood and bone marrow cells and by immunoperoxidase studies using paraffin sections. In bone marrow and peripheral(More)
To describe GVHR in small bowel transplantation and its underlying mechanisms and to find methods for circumventing that response, accessory small bowel transplantation was carried out in the rat model. Animals not treated with cyclosporine, irradiation, or removal of the mesenteric lymph nodes of the graft died within 22 days postoperatively due to graft(More)
To clarify contradictory information in the literature about the immunogenic effect of the trachea, tracheal transplantations were performed orthotopically and heterotopically in two combinations of inbred rat strains. In all in vivo experiments it was possible to demonstrate a considerable systemic immunisation by transplantation antigens. There were no(More)
