Graft vessel disease (GVD) is a major cause of graft loss after the first year following transplantation. GVD is a complex, multifunctional process that involves immunological as well as non-immunological events such as ischaemia/reperfusion injury. An important target cell to interfere with the development of GVD is the smooth muscle cell (SMC).(More)
Presentation of antigen in the form of immune complexes to B lymphocytes by follicular dendritic cells (FDC) is considered to be a central step in the generation of memory B cells. During this process, which takes place in the microenvironment of the germinal center, B cells and FDC are in close physical contact. In the present study, we have explored the(More)
A postulated mechanism for autoimmune disorders is that the immunoreactivity develops against bacterial antigens which show a high degree of sequence homology with mammalian proteins. The mycobacterial 65 kD heat shock protein (hsp) has been implicated in several forms of arthritis. Substantial amounts of the human 60 kD homologue (hsp60) were produced by(More)
We evaluated the presence of anterior pituitary hormones; follicle-stimulating hormone (FSH) and its beta-subunit (beta-FSH), luteinizing hormone (LH) and its beta-subunit (beta-LH), beta-subunit of thyroid-stimulating hormone (beta-TSH), adrenocorticotropic hormone (ACTH), growth hormone (GH), and prolactin (PRL); the placental hormone human chorionic(More)
The histology of epithelium-free areas in the subcapsular region of the thymus was studied in Wistar rats. Lymphocytes in these areas were CD4/CD8 double-positive, TCR alpha/beta positive in low intensity, and in CD5 labeling either negative or positive in low intensity. There was a high proliferative activity as assessed by bromodeoxyuridine incorporation(More)
The presence of nerve-like fibers in the human thymus was studied by immunohistochemistry on frozen tissue sections and sections of formalin-fixed paraffin-embedded tissue, for neurofilaments (Nf) of 68-, 160-, and 200-kDa (neuron-specific structural proteins), neuron-specific protein PGP9.5, tyrosin hydroxylase (noradrenergic innervation), chromogranin A(More)
An immunohistochemical study was done for the presence of tyrosine hydroxylase (noradrenergic innervation), neuron-specific protein PGP9.5, and anterior pituitary hormones (beta-subunit of follicle-stimulating hormone, growth hormone, beta-subunit of luteinizing hormone, prolactin, and beta-subunit of thyroid-stimulating hormone) in cultured thymic(More)
It has been proposed that Natural Killer (NK) cell activity is involved in host defence against neoplasia, and that NK cells react with or recognize the transferrin receptor (TrR) on target cells. HNK-1 expression has been related to NK cell function. Therefore, in 118 cases of non-Hodgkin's lymphoma (NHL) we studied the occurrence and distribution of(More)
A lymphocyte stimulation assay is described which detects immune reactivity to antigens derived from the CaSki cervical carcinoma cell line. Taking a stimulation index of greater than 4.1 as positive, the peripheral blood lymphocytes of 14/20 patients (70%) with untreated dysplasia or carcinoma-in-situ, 8/19 patients (42%) with untreated macroinvasive(More)
