We report herein two cases of immunoglobulin G4 (IgG4)-related retroperitoneal fibrosis (RF) showing monoclonal B-cell proliferation.A 76-year-old man (case 1) underwent right hemicolec-tomy because of ascending colon carcinoma. At surgery, a left peritoneal tumor was incidentally found, and a...
Epstein-Barr virus (EBV) positive diffuse large B-cell lymphoma (DLBCL) of the elderly, initially described in 2003, is a provisional entity in the 2008 World Health Organization classification system and is defined as an EBV-positive monoclonal large B-cell proliferation that occurs in patients ...
摘要: Mature B-cell or Burkitt's-cell leukemias presenting with a L3 morphology according to the FAB classification (Bennett et al., 1976), and surface immunoglobulins together with B-cell markers have...关键词: Philadelphia chromosome Burkitt's leukaemia cytogenetics malignant transformation ...
and AIRE-positive but UEA-1-negative (suggesting that this cell is not an mTEC but is a B cell lineage cell or that this cell is an immature or aged mTEC), whereas cell 4 was UEA-1-positive but AIRE- and X-NANA-negative (suggesting that this cell is an AIRE-negative mTEC). Cell ...
MH Dan,TF Beals,B Schnitzer 摘要: A case of metastatic small cell carcinoma of the lung is reported; initially, on the basis of morphology, phenotyping with monoclonal antibodies, and cytochemistry, the carcinoma was interpreted as a hematopoietic neoplasm. Noncohesive blast-like cells observed in...
Serial tissue sections were stained for IgE by direct (polyclonal antibody) and indirect (monoclonal antibody) immunofluorescence methods. Adjacent sections were subjected to conventional mast cell staining (astra blue). In all mucosal specimens from the jejunum and in 8 rectal ones, numerous cells ...
A Gebert,G Hach,H Bartels - 《Cell & Tissue Research》 被引量: 172发表: 1992年 Expression of glial filament protein (GFP) in nerve sheaths and non-neural cells re-examined using monoclonal antibodies, with special emphasis on the co-e... The histological distribution of these GFP-positive...
The histogenesis of primary cutaneous marginal zone B-cell lymphoma (PCMZL) has not yet been clarified. Plasma-cytoid dendritic cells (PDC) play a crucial role in the initiation of immune responses and activation of T-cells and B-cells. We analyzed the presence of PDC by immunohistochemistry ...
Two monoclonal antibodies specific for the mouse T-cell receptor (Tcr) have been established by immunization with a V β 11 + T-cell clone, clone C6. One is a rat antibody, KT11 (IgG2b, k), specific for the V β chain of C6, V β 11. This was demonstrated by the fact that the...
Synovial fibroblasts (SF) were reported to produce B cell activating factor (BAFF) in response to stimulation with interferon-γ (IFN-γ) or tumor necrosis factor (TNF). However, the influence of these pro-inflammatory cytokines on other receptors/ligands of the TNF superfamily or associated cyto...
