Detection of Human Monocyte-Reactive Alloantibodies by Flow Cytometry After Selective Downmodulation of the Fc Receptor

چکیده

Monocyte-reactive human alloantibodies may be of importance in situations such as transfusion reactions and bone marrow and kidney transplantation. So far, only complementbinding monocyte-reactive antibodies can be detected with a cytotoxicity assay. No antiglobulin assays are yet available that also detect noncomplement-fixing monocyte-reactive antibodies. The binding of monomeric IgG with high affinity to the Fc receptor I (FcRI) on monocytes has severely hampered the development of such an assay until now. We report on the selective removal of the FcRl from monocytes to test human sera in a flow cytofluorometry assay for the presence of monocyte-reactive IgG alloantibodies. Selective

Receptor for advanced glycation end products involved in circulating endothelial cells release from human coronary endothelial cells induced by C-reactive protein

Objective(s): This study was designed to investigate the effect of receptor for advanced glycation end products (RAGE), S100A12 and C-reactive protein (CRP) on the release of circulating endothelial cells (CECs) from human coronary artery endothelial cells (HCAECs). Materials and Methods: HCAECs were cultured in increasing concentration of CRP (0, 12.5, 25, 50μg/ml) or S100A12 protein (0, 4, 1...

The use of allele-specific recombinant Fc gamma receptor IIIb antigens for the detection of granulocyte antibodies.

The Fcgamma receptor IIIb (FcgammaRIIIb) for the Fc domain of IgG is expressed exclusively on neutrophils. The FcgammaRIIIb bears allotypic polymorphisms referred to as NA1, NA2, and SH, which are known for their frequent involvement in alloimmune and autoimmune neutropenias as well as in transfusion reactions. The bactericidal capacity of isolated neutrophils is easily activatable, and activat...

Chemoattractants Induce a Rapid and Transient Upregulation of Monocyte α4 Integrin Affinity for Vascular Cell Adhesion Molecule 1 Which Mediates Arrest

Chemoattractants and chemokines induce arrest of rolling monocytes during emigration from blood into tissues. In this study, we demonstrated that alpha4 integrin affinity for vascular cell adhesion molecule (VCAM)-1 was upregulated rapidly and transiently by chemoattractants and stromal cell-derived factor (SDF)-1alpha and mediated monocyte arrest. alpha4 integrin affinity changes were detected...
