Fc-receptor variants of a mouse macrophage cell line.
Variants of the J774 mouse macrophage cell line that lack immunologically important membrane receptors were isolated. After mutagenesis, variants were selected in a metrizamide gradient that separated cells heavily rosetted with sheep erythrocytes (E) coated with rabbit anti-E IgG (EIgG) from poorly rosetted cells. Stable variants that exhibited altered binding were found with a frequency of <1...
متن کاملFunction and regulation of a murine macrophage-specific IgG Fc receptor, Fc gamma R-alpha
Ligand binding specificities of two cloned murine Fc gamma Rs (Fc gamma R-alpha, Fc gamma R-beta [9]) were determined by gene transfer into Fc gamma R negative cell lines. Both receptors were expressed as full-length molecules capable of IgG immune complex binding that was inhibitable by the mAb 2.4G2. The ligand binding profiles of these receptors were indistinguishable whereby both bound immu...
متن کاملMolecular mechanisms of macrophage Toll-like receptor–Fc receptor synergy
Macrophages (MØs) are a key cell type of both the innate and the adaptive immune response and can tailor their response to prevailing conditions. To sense the host's status, MØs employ two classes of receptors: Toll-like receptors (TLRs), which are sensors for pathogen-derived material, and Fcγ receptors (FcγRs) that are detectors of the adaptive immune response. How MØs integrate the input fro...
متن کاملCharacterization of a monoclonal antibody directed against mouse macrophage and lymphocyte Fc receptors
To investigate the antigenic relationship between the macrophage and lymphocyte Fc receptors (FcR), a monoclonal antibody capable of blocking mouse macrophage Fc receptors was selected. Hybrids were formed by fusing the P3U1 mouse myeloma and spleen cells from a rat immunized with the mouse macrophage-like cell lines J774 and P388D1. The Fab fragment of the monoclonal IgG secreted by clone 2.4G...
متن کاملFc receptor-mediated inhibition of murine B-lymphocyte activation
Immobilized antigen-antibody complexes are able to inhibit the mitogenic response of murine spleen cells to the B-cell mitogen 8-bromo-3',5'-cyclic guanosine monophosphoric acid. This this inhibition is dependent on intact Fc fragments in the immobilized complexes. Soluble complexes do not mediate this inhibition. When lipopolysaccharide (lps) activation of B cells was studied, it was found tha...
