The IgE Receptors (Introduction)

1987
It is well-known that stimulation of the receptor, with high affinity for IgE on mast cells and basophils, initiates an allergic reaction. This has been extensively studied during the past 20 years. There is no doubt that this receptor is of major importance in the understanding of allergic diseases.

The high-affinity receptor for IgE

Current Opinion in Immunology, 1990
Many cells of the immune system have cell-surface receptors that bind IgE with low afhmity [FCE receptor (FcER) II] (Delespesse et al, this issue, pp 506512). In contrast, the high-aifmity receptor for IgE (FcsRI) is found exclusively on the surface of mast cells and basophils.

Lymphocytes Bearing Receptors for IgE

The Journal of Immunology, 1979
Abstract Culture of normal rat lymphocytes with rat IgE at 37°C resulted in an increase in the proportion of FcεR(+) cells. In agreement with this finding, the ability of normal lymphocytes to bind 125I-IgE markedly increased after overnight incubation with IgE.

Cytofluorometric quantification of IgE and IgE receptors on individual mast cells

Journal of Immunological Methods, 1994
Information about the IgE receptor and IgE content of mast cells under different conditions in vivo is essential for further understanding the functions of the mast cell-IgE system. A cytofluorometric method for measuring cell-bound IgE on individual mast cells was therefore explored using peritoneal mast cells of Sprague-Dawley rats infected with the ...

IgE Receptors on Lymphocytes and IgE-Binding Factors

1991
There are two types of Fc receptors for IgE (Fc∈R): the high-affinity Fc∈R (Fc∈RI) (reviewed in Metzger, 1988) and the low-affinity Fc∈R (Fc∈RII) (reviewed in Spiegelberg, 1984). The former is expressed on basophils and mast cells, whereas the latter is expressed on lymphocytes (Lawrence et al., 1975), monocytes and macrophages (A. Capron et al., 1975;

Proteolytic fragments of the receptors for IgE

Immunology Letters, 1982
Partially purified IgE receptor(s) of rat basophilic leukemia cells (RBL) designated R and H and having apparent molecular weight of 45,000 and 55,000 daltons, respectively, were subjected to proteolysis with papain. Polyacrylamide gel electrophoresis of the digests in the presence of sodium dodecyl sulfate revealed a difference in the size and number ...

Induction of Ige Receptors on Human Lymphocytes

Immunological Communications, 1983
A mouse myeloma IgE protein was cross-linked with dimethylsuberimidate to induce polymerization and incubated with normal human peripheral blood T lymphocytes in tissue culture. After 24 hours at 37 degrees C approximately 30% of the cells formed rosettes with IgE sensitized red cells as compared with much lower levels in the controls.

Polymeric Ig receptor expression in hepatocellular carcinoma

European Journal of Cancer, 1992
The cellular localisation of the polymeric Ig receptor (pIg-R) and carcinoembryonic antigen (CEA), hepatic and biliary cell markers, were investigated in patients with hepatocellular carcinoma (HCC) and high serum levels of secretory component. Serum SC were increased 6-20-fold in 8 HCC patients compared with normal subjects.

IgE Receptors on Lymphocytes

1986
Peripheral blood lymphocytes (PBL), B and T cells from nonatopic donors, patients with allergic rhinitis and/or asthma (“mild atopic”, 300–900 IU IgE/ml), severe atopic dermatitis (1000–40000 IU IgE/ml) and the hyper-IgE Syndrome (> 7000 IU IgE/ml) were examined for IgE and IgG Fc receptor positive cells (Fc ɛ R, Fc γ R).

The receptor for IgE on blood platelets

European Journal of Immunology, 1986
AbstractHighly purified blood platelets from man and rat could be induced into cytotoxic effectors against schistosome larvae by an IgE‐dependent mechanism. Such a process implied the existence of a receptor for the Fc part of IgE on the surface of these blood elements.
