The transmembrane glycoprotein CD83 is rapidly upregulated on murine and human DC upon maturation and therefore a costimulatory function for T cell activation has been suggested. Studies employing human APC indeed showed that CD83 expression was positively correlated to the stimulatory capacity of the APC. Murine APC that were CD83 deficient however, did(More)
8 cases were studied to determine whether immunohistochemical investigation with anti-GFAP could contribute to confirming a primary brain tumor origin for an extracranial metastasis. The materials studied consisted of 3 glioblastomas, 3 anaplastic astrocytomas, and 2 medulloblastomas, along with their extracranial metastases. GFAP could be(More)
The transmembrane glycoprotein CD83 has been described as a specific maturation marker for dendritic cells and several lines of evidence suggest that CD83 regulates thymic T cell maturation as well as peripheral T cell activation. Here we show for the first time that CD83 is involved also in the regulation of B cell function. CD83 is up-regulated on(More)
The transmembrane glycoprotein CD83 is an important regulator of both thymic T cell maturation and peripheral T cell response. Recent studies suggested that CD83 is also involved in the regulation of B cell maturation, activation, and homeostasis. In this study, we show that in vivo overexpression of CD83 dose dependently interfered with the Ig response to(More)
The murine transmembrane glycoprotein CD83 is an important regulator for both thymic T cell maturation and peripheral T cell responses. Recently, we reported that CD83 also has a function on B cells: Ubiquitous transgenic (Tg) expression of CD83 interfered with the immunoglobulin (Ig) response to infectious agents and to T cell dependent as well as T cell(More)
The conserved transmembrane glycoprotein CD83 was originally described as highly specific marker for mature dendritic cells in the peripheral circulation. Besides its regulatory role in thymic T cell maturation and peripheral T cell activation, recent studies suggest, that CD83 is also involved in the regulation of B cell maturation, homeostasis and(More)
The central function of murine CD83 that is expressed on thymic epithelial cells is to induce the progression of double-positive thymocytes to single CD4-positive T cells. Several lines of evidence suggest an additional role for CD83 in the regulation of peripheral T and B cell responses. Here we show that CD83 is expressed by immature B cells and regulates(More)
During August 2010-December 2012, we conducted a study of patients in Ghana who had Buruli ulcer, caused by Mycobacterium ulcerans, and found that 23% were co-infected with Mansonella perstans nematodes; 13% of controls also had M. perstans infection. M. perstans co-infection should be considered in the diagnosis and treatment of Buruli ulcer.
CD83 is a transmembrane glycoprotein that is rapidly up-regulated on activated B cells. Although CD83 itself is incapable to transduce intracellular signaling, it acts as a negative regulator of B cell function. We have recently described that a single application of anti-CD83 antibody results in dramatically enhanced production of antigen-specific IgG1 but(More)
