6730 Background: Waldenstrom's macroglobulinemia (WM) is a B-cell malignancy, recently established by a consensus panel to be represented by the underlying WHO/REAL pathological diagnosis of IgM secreting lymphoplasmacytic lymphoma (Semin Oncology 30:110, 2003). The expression of CD5, CD10, and CD23 in WM remains controversial, and confusion with other B-cell malignancies has often resulted. ...
Antibody-secreting plasma cells with unique CD5+IgG+CD21lo phenotype developed in humanized NOG mice
The developmental process of human antibody (Ab)-secreting B cells in humanized mice is not fully defined. To examine the characteristics of class-switched and Absecreting B cells in humanized mice, we analyzed NOD/Shi-scid, common γc-null mice reconstituted with cord blood-derived hematopoietic stem cells (CB-NOG). Most of the CD138-positive plasmablasts (PBs)/plasma cells (PCs) in the NOG spl...
CD5 is a cell surface molecule involved in antigen recognition and is present on all T lymphocytes and a subset of B lymphocytes. The purpose of this study was to examine CD5+ expression on peripheral blood B cells from healthy, noninfected cattle and cattle with subclinical and clinical paratuberculosis. Peripheral blood mononuclear cells (PBMC) were freshly isolated or cultured for 7 days in ...
Accumulated evidence implies that hepatitis C virus (HCV) infects not only the liver but also the immune system. A lymphocyte-specific CD5 molecule was recently identified as essential for infection of T cells with native, patient-derived HCV. To assess whether the proposed hepatocyte receptors may also contribute to HCV lymphotropism, expression of scavenger receptor-class B type 1 (SR-B1), cl...
Autoimmunity and inflammation are controlled in part by regulatory B cells, including a recently identified IL-10-competent CD1d(high)CD5(+) B cell subset termed B10 cells that represents 1-3% of adult mouse spleen B cells. In this study, pathways that influence B10 cell generation and IL-10 production were identified and compared with previously described regulatory B cells. IL-10-competent B ...
Use of the appropriate propagule size can maximize propagation rate strawberry (Fragaria × ananassa) transplants in an autotrophic transplant production method, a novel method plant factory with artificial lighting for production. During 90 days after planting initial propagules, cumulative number produced from propagules 5 mm crown diameter (CD5) was greater than those 4 (CD4) or 6 (CD6). Time...
The responsiveness and diversity of peripheral B-cell repertoire decreases with age, possibly because of B-cell clonal expansions, as suggested by the incidence of serum monoclonal immunoglobulins and of monoclonal chronic lymphocytic leukemia (CLL)-like B lymphocytes in clinically silent adults. We phenotyped peripheral blood cells from 500 healthy subjects older than 65 years with no history ...
Food allergy is a hypersensitive immune reaction to food proteins. We have previously demonstrated the presence of IL-10-producing CD5(+) B cells and suggested their potential role in regulating cow's milk casein allergy in humans and IgE-mediated anaphylaxis in mice. In this study, we determined whether IL-10-producing CD5(+) regulatory B cells control casein-induced food allergic responses in...
