Immunoglobulin E and its interactions with receptors FcϵRI and CD23 play a central role in allergic disease. Omalizumab, a clinically approved therapeutic antibody, inhibits the interaction between IgE and FcϵRI, preventing mast cell and basophil activation, and blocks IgE binding to CD23 on B cells and antigen-presenting cells. We solved the crystal structure of the complex between an omalizum...
Reactive plasmacytosis is a transient expansion of plasma cell progenitors and precursors. This rare condition has been reported to occur mainly in infections and tumors. We describe a case of acute hepatitis A presenting with marked peripheral blood plasmacytosis. Plasma cells made up 27.5% of the mononuclear cells and had the immunophenotype CD10-CD19+CD20-CD21-CD23-CD34-CD38++HLA-DR+. Althou...
B lymphocytes are involved in inflammation and are related to insulin resistance in obesity and type 2 diabetes (T2D). This study investigated the phenotype and frequency of B-lymphocyte subsets in subjects recently diagnosed with T2D (n = 60), impaired glucose regulation (IGR, n = 73), and normal glucose tolerance (NGT, n = 169) by flow cytometry. T2D subjects had an increased percentage of CD...
CD21int CD23+ IgM+ mouse follicular B cells comprise the bulk of the mature B-cell compartment, but it is not known whether these cells contribute to the humoral antibody response. We show using a direct RT-PCR method for antigen-specific VH, that FACS-sorted mouse CD21int CD23+ B cells express specific secretory IgM VH transcripts in response to immunization and also exhibit a memory response....
We previously reported that CD23/FcepsilonRII (low-affinity IgE receptor) is expressed on human intestinal epithelial cells and is responsible for transepithelial transport of IgE. In this study, we compared the transport of IgE with that of immune complexes in both the apical-to-serosal and the serosal-to-apical directions across HT29 epithelial cell layers and examined the effects of two p38 ...
