    Direct Allorecognition Promotes Activation of Bystander Dendritic Cells and Licenses Them for Th1 Priming: A Functional Link Between Direct and Indirect Allosensitization (2005)

    Notes: T-cell sensitization to indirectly presented alloantigens (indirect pathway of allorecognition) plays a critical role in chronic rejection. The usual very efficient priming of such self-restricted, T helper type 1 (Th1)-deviated CD4+ T cells obviously conflicts with the fact that allogeneic MHC molecules are poorly immunogenic per se. The aim of the present study is to elucidate whether direct allosensitization induces production of inflammatory mediators that may affect recruitment and activation of immature bystander (host) dendritic cells (DC). These potential mechanisms were studied in vitro by conducting primary allogeneic mixed leucocyte reactions (MLR), mimicking the priming phase in secondary lymphoid organs, and secondary MLR, mimicking the effector phase within the graft. Primary, and particularly secondary, MLR supernatants were found to contain high levels of monocyte/immature DC-recruiting CC chemokines and pro-inflammatory cytokines. Exposure of immature DC to primary or secondary MLR supernatants was found to upregulate CD40 expression and further enhanced lipopolysaccharide-induced interleukin-12 (IL-12) p70 production. Secondary MLR supernatants additionally induced upregulation of CD86 and deviated allogeneic T-cell responses towards Th1 (enhanced interferon-γ production without concomitant induction of detectable IL-4 or IL-10 production). These findings indicate that direct allorecognition may act as a Th1-deviating adjuvant for indirect allosensitization.

    T-Lymphocyte Subsets and HLA-DR-Expressing Cells in Rejected Human Kidney Grafts (1983)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: This communication describes an immunohistochemical analysis of rejected human renal allografts. T-lymphocyte subsets were identified in frozen tissue sections, by Leu 1 (anti- ‘pan’ T lymphocytes). Leu 2a (anti- ‘cytotoxic/suppressor’ T cells), and Leu 3a (anti- ‘helper/inducer’ T cells) monoclonal antibodies. In addition, HLA-DR-positive cells were identified by simultaneous labelling with heterologous anti-HLA-DR antibodies. T cells dominated the cellular infiltrates in acute cellular rejection. Leu-3a-positive cells were more numerous than Leu-2a-positive cells. The Leu-3a-positive cells usually appeared in clusters, whereas the Leu-2a-positive cells appeared scattered in the tissue. HLA-DR-positive non-T cells were found within clusters of T ‘helper/inducer’ cells. The cell pattern shares many features with the findings in detayed-type hypersensitivity reactions.

    Presence of Human 65 kD Heat Shock Protein (hsp) in Inflamed Joints and Subcutaneous Nodules of RA Patients (1990)

    Notes: Monoclonal antibodies to the human homologue of the bacterial 65 kD heat shock protein (hsp) were used to investigate the tissue distribution of endogenous hsp 65 in normal versus rheumatoid synovial tissue, in subcutaneous nodules of patients with rheumatoid arthritis (RA) and in several instances of non-rheumatoid inflammation. A strong reactivity of the anti-hsp antibody was found in the cartilage-pannus junction in rheumatoid joints and in rheumatoid nodules, but not in normal joints or in normal or inflamed kidney or liver (irreversible graft rejection, chronic glomerulonephritis or primary biliary cirrhosis). The findings provide a new hypothetical explanation for a role of T cells reactive with the 65 kD hsp in the generation of both articular and extra-articular lesions in chronic rheumatoid arthritis.

    T-Cell Receptor V-Gene Usage in Synovial Fluid and Synovial Tissue from RA Patients (1992)

    Notes: The question of whether there is a preferential use of certain V genes in T cells entering an inflamed joint has hitherto been studied mainly using unfractionated cells from synovial fluid and tissue respectively, and no clear answer to the question has yet been provided. Concomitantly. evidence has been provided that the use of V genes may differ considerably between CD4+ and CD8+ T cells, and consequently that detection of biased V-gene expression within an inflammatory lesion may require separate analysis of the two T-cell subsets.In this paper we have therefore studied T-cell receptor V-gene expression in rheumatoid arthritis by means of double stainings of synovial fluid and blood for available anti-TCR monoclonal antibodies and antibodies to CD4 and CD8. respectively. Double stainings were also performed with anti-TCR antibodies and antibodies to activation markers HLA-DR and 1L-2R. A certain bias towards the preferential use of certain V genes was seen particularly in the synovial fluid samples within both the CD4+ and CD8+ T-cell populations, but no uniform pattern was evident among the 35 patients investigated.

    The Anti-Leu4 (CD3) Monoclonal Antibody Reacts with Proximal Tubular Cells of the Human Kidney (1989)

    Notes: A recent observation that certain kidney tubular cells, especially those in the normal kidney, were positively stained with the anti-Leu4 monoclonal antibody (MoAb) led us to investigate systematically the reactivity of three different anti-CD3 MoAb with a panel of normal human kidneys. Using immunohistochemical and immunofluorescence staining techniques, the anti-Leu4 MoAb was found to react with proximal tubular cells in all eight examined kidneys, while no tubular-cells reactivity was observed with the OKT3 or DAKO-T3 MoAb. In each kidney, however, all three antibodies reacted with a similar number of occasionally encountered T cells. The G11 MoAb, which has been reported to react with a calcium receptor-associated molecule, and the anti-Leu4 MoAb showed almost identical patterns of tubular-cell reactivity. The observed co-distribution of Leu4-expressing structures with a putative Ca2+ sensor in the kidney and the fact that binding of anti-Leu4 to T cells induces C2+-mediated signal transduction, warrant further studies on a potential role of Leu4-expressing structures in Ca2+ regulation of proximal tubular cells.
