The beta subunit of the Fc epsilon RI is associated with the Fc gamma RIII on mast cells
Fc epsilon RI is a tetrameric receptor, composed of a ligand recognition subunit, alpha, a beta chain, and dimeric gamma chains. Previous studies have indicated that the dimeric gamma chain is associated with Fc gamma RIIIA (CD16) on natural killer cells and macrophages as well as the clonotypic T cell receptor. Here we show that in mast cells, in addition to the dimeric gamma chains, the beta ...
متن کاملThe / 3 Subunit of the FceRI Is Associated with the Fc 3 ~ RIII on Mast Cells
FceRI is a tetrameric receptor, composed of a ligand recognition subunit, c~, a fl chain, and dimeric 3' chains. Previous studies have indicated that the dimeric 3~ chain is associated with Fc"/RIIIA (CD16) on natural killer cells and macrophages as well as the clonotypic T cell receptor. Here we show that in mast cells, in addition to the dimeric 3 ~ chains, the fl subunit is associated not on...
متن کاملMast cells lacking the high affinity immunoglobulin E receptor are deficient in Fc epsilon RI gamma messenger RNA
A population of cells that express mast cell markers, including the membrane protein p161, but that lack expression of the high affinity IgE receptor, Fc epsilon RI, can be routinely grown from bone marrow. Ionomycin, but not IgE immune complexes, causes these cells to release serotonin and to express IL-3 and IL-13 mRNA, consistent with their being FC epsilon RI-deficient mast cells. These p16...
متن کاملLymphoma depletion during CD 20 immunotherapy in mice is mediated by macrophage Fc RI , Fc RIII , and Fc RIV
Despite the demonstrated clinical efficacy of CD20 monoclonal antibody (mAb) for lymphoma therapy, the in vivo mechanisms of tumor depletion remain controversial and variable. To identify the molecular mechanisms responsible for lymphoma killing by CD20 mAb in a homologous system amenable to mechanistic studies and genetic manipulation, a mouse lymphoma model was developed using primary tumor c...
متن کاملIdentification of the low affinity receptor for immunoglobulin E on mouse mast cells and macrophages as Fc gamma RII and Fc gamma RIII
In addition to their well characterized high affinity immunoglobulin E (IgE) receptors (Fc epsilon RI) mast cells have long been suspected to express undefined Fc receptors capable of binding IgE with low affinity. In this paper, we show that Fc gamma RII and Fc gamma RIII, but not Mac-2, on mouse mast cells and macrophages bind IgE-immune complexes. This binding is efficiently competed by 2.4G...
