    Notes: Small intestinal biopsies from psoriasis patients and from normal controls were obtained with a multipurpose suction tube. The tissue was incubated with tritiated thymidine and processed for autoradiography.Labelling indices (LI) were calculated by counting labelled cells in all crypt cross-sections through the entire proliferative compartment. LI was increased in psoriatics as compared to controls indicating alterations in small intestinal epithelial cell kinetics in psoriasis.A continuous labelling allowing us to calculate the S-phase duration and the total cell turnover time was probably not obtained within an experimental period.

    Notes: Phytohaemagglutinin-induced human T-lymphocyte colony formation in semisolid agar culture is the properly of erythrocyte rosette-forming cells (E-RFC) negative for the 7S IgG receptor (FcR−). E-RFC positive for the 7S IgG receptor (FcR+), on the other hand, exhibit a limited capacity for colony formation and suppress colonies formed by FcR− E-RFC. T colonies are composed of small lymphocytes and lymphoblasts, the vast majority being negative for the Fc receptor. Most colony cells (86%) carry the Leu 3a antigen, suggesting that they belong to the inducer/helper T-cell subset, FcR+ colony suppressor cells are small, slowly sedimenting cells (sedimentation velocity 〈 3.8 mm/h) and are strongly adherent to plastic, and their activity depends on the ability to synthesize DNA.

    Notes: Tissue inhibitor of metalloproteinases (TIMP)-2 is a highly conserved molecule, which binds both active and latent matrix metalloproteinase (MMP)-2. TIMP-2 is also involved in the activation of MMP-2 on the cell surface. A quantitative enzyme-linked immunosorbent assay (ELISA) was established and optimized for measurement of TIMP-2 in plasma. The capturing antibody in the ELISA was a monoclonal, while the detecting antibody was a chicken polyclonal antibody recognizing the native form of human TIMP-2. The levels of TIMP-2 were measured in ethylenediaminetetraacetic acid (EDTA) and citrate plasma from healthy donors. The median values were determined as 163 ng/ml (n = 186) with a range of 109–253 ng/ml for EDTA plasma and 139 ng/ml (n = 77) with a range of 95–223 ng/ml for citrate plasma. The TIMP-2 concentration in citrate plasma from 15 patients with advanced, stage IV breast cancer had a median value of 160 ng/ml, only slightly higher but statistically distinguishable from the level found in citrate plasma from the healthy donors. In addition, the TIMP-2 concentration in EDTA plasma from colorectal cancer patients revealed a significantly higher level in plasma from patients with Dukes stage A (P = 0.01) compared with patients with more advanced Dukes stages.

    Generation of Antibodies to the Urokinase Receptor (uPAR) by DNA Immunization of uPAR Knockout Mice: Membrane-Bound uPAR is Not Required for an Antibody Response (2003)

    Notes: The urokinase receptor (uPAR) is a glycolipid-anchored cell surface glycoprotein that plays a central role in extracellular proteolysis during tissue remodeling processes including cancer invasion. Furthermore, uPAR is found on the surface of both dendritic cells (DCs) and T cells, and has been proposed to play a role in DC-induced T-cell activation and, therefore, in the induction of an immune response. In order to investigate the possibility of using DNA immunization for the generation of poly- and monoclonal antibodies to uPAR, we injected wild-type mice and mice deficient in uPAR (uPAR knockouts) intramuscularly with plasmid DNA encoding a carboxy-terminal truncated soluble form of the human uPAR. Multiple injections of 100 µg of DNA resulted in a strong and specific antibody response in all mice irrespective of genotype. Antisera with a maximum titre of 32,000 were obtained, comparable with that obtained after immunization with recombinant uPAR. The subclass distribution of uPAR-specific antibodies in the sera demonstrated the induction of a mixed TH1/TH2 response, irrespective of the genotype of the mice. Our results demonstrate the possibility of generating high titre antibodies to uPAR by DNA immunization of wild-type as well as uPAR knockout mice, and that cell surface uPAR is not indispensable for the generation of a humoral immune response.

    Notes: Specific HLA antibodies were used to eliminate donor and recipient cells, respectively, from lymphocyte suspensions prepared from the blood of a child who had been transplanted with bone marrow from an HLA-A- and HLA-B-incompatible, HLA-D-compatible donor. About 70% of the lymphocytes were of donor HLA type, the remaining of recipient type. The phytohemagglutinin-responsive lymphocytes were exclusively limited to the lymphocyte population carrying donor-type HLA antigens. Membrane immunofluorescence investigations of the donor and recipient populations showed a low percentage of IgM-positive lymphocytes in the donor population and an extremely high proportion of IgM-positive lymphocytes in the recipient population. About 90% of the donor lymphocytes were T cells, as judged by their capacity to form rosettes between sheep erythrocytes and T lymphocytes; no cells in the recipient cell population expressed this ability.

    Notes: Paraffin-wax embedded specimens from 30 cases of colonic adenocarcinoma were investigated for immunoreactivity for the receptor of urokinase-type plasminogen activator (uPAR). In all cases there was a strong signal, predominantly at the invasive foci. The positive cells were mainly tumour-infiltrating macrophages but neutrophils and eosinophils were also strongly stained. The neoplastic cells were positive in 19 of the samples with staining of occasional or a moderate number of cells. In uninvolved, normal-appearing mucosa adjacent to the malignant infiltrates, immunostaining of both macrophages and neutrophils was seen, but the labelling was less intense than that seen in the malignant lesions. Weak to moderate staining of normal intestinal epithelium was also seen at the luminal surface. Comparison between immunoreactivity and in situ hybridization showed a similar distribution of protein and mRNA with two exceptions: first, neutrophils (strongly immunoreactive for uPAR) were negative or only weakly positive for uPAR mRNA; and second, many cancer cells at invasive foci showed prominent hybridization signals but no detectable uPAR immunoreactivity. Together with previous findings of urokinase plasminogen activator (uPA) protein and mRNA being expressed in tumour-infiltrating fibroblast-Iike cells at the invasive foci, these results support the view that the uPA pathway of plasminogen activation is involved in tissue degradation in colon cancer. The results also extend and consolidate an emerging picture of non-neoplastic tumour stromal cells producing molecules involved in the generation and regulation of extracellular proteolysis in cancer.

    Notes: The blood levels of the soluble forms of the urokinase receptor (suPAR) are increased in human immunodeficiency virus (HIV)-1-infected patients. This study investigated whether the release of urokinase-type plasminogen activator receptor (uPAR) in whole-blood cultures was affected by HIV infection. The release of different uPAR forms in whole-blood cultures incubated 24 h with or without phytohemagglutinin and lipopolysaccharide was analysed in 47 HIV patients and 19 controls. suPAR was measured by enzyme-linked immunosorbent assay (ELISA) (bulk-suPAR) and three different time-resolved fluorescence immunoassays measuring three-domain suPAR [suPAR(I–III)], three- and two-domain suPAR [suPAR(I–III) + suPAR(II–III)] and one-domain suPAR [suPAR(I)]. The uPAR release was correlated to leucocyte subpopulations and plasma levels of suPAR. The stimulated net whole-blood culture release of bulk-uPAR, uPAR(I–III), uPAR(II–III) and uPAR(I) was reduced in HIV patients (all P 〈 0.01), whereas the spontaneous bulk-uPAR and uPAR(I–III) release was increased in HIV patients (both P 〈 0.05). The stimulated uPAR release in whole-blood cultures correlated well to leucocytes and circulating suPAR levels in controls, whereas the correlation was weaker to leucocytes and nonexisting to circulating suPAR levels in HIV patients. These findings demonstrate that HIV infection affects stimulated and spontaneous uPAR release in whole-blood cultures. Given that high blood levels of suPAR in HIV patients are linked to immune activation, the perturbations in uPAR release in whole-blood cultures from HIV patients may also reflect immune activation.

    Notes: Leucocyte expression of the urokinase receptor [urokinase-type plasminogen activator receptor (uPAR)] is regulated by inflammatory mediators. This study investigated the in vivo effect of endotoxin, interleukin (IL)-6 and tumour necrosis factor (TNF)-α on uPAR-release in vivo and in vitro in humans. Healthy subjects received intravenous endotoxin injection [high-dose, 2 ng/kg (n = 8) and low-dose, 0.06 ng/kg (n = 7)], coadministration of 0.06 ng/kg endotoxin and 3 h recombinant human (rh)IL-6 infusion (n = 7) or 3 h infusion of rhIL-6 (n = 6), rhTNF-α (n = 6) or NaCl (n = 5). Soluble uPAR (suPAR) was measured by enzyme-linked immunosorbent assay in plasma and supernatants from unstimulated and phytohaemagglutinin and lipopolysaccharide-stimulated peripheral blood mononuclear cell (PBMC) cultures incubated for 24 h. The spontaneous and stimulated uPAR-release from PBMC cultures was enhanced 5 h after low-dose endotoxin (both P 〈 0.05), but coadministration of rhIL-6 during low-dose endotoxaemia abolished this enhanced uPAR release. High-dose endotoxin increased plasma suPAR levels (P 〈 0.001) whereas low-dose endotoxin, rhIL-6 or TNF-α did not influence uPAR release in vivo to such degree that a systemic effect on the plasma suPAR level was detectable. Even subclinical doses of endotoxin in vivo enhance the capacity of PBMC to release uPAR after incubation in vitro. The inhibitory effect of IL-6 on endotoxin-mediated uPAR-release in vitro suggests that IL-6 has anti-inflammatory effects on endotoxin-mediated inflammation.
