Natural human IgE peptide‐specific CTL inhibit human IgE production and eliminate U266 in HLA‐A2 transgenic rodents

IgE receptors on human basophils. Relationship to serum IgE concentration.

As reported previously, and confirmed here in 26 donors, the serum IgE level (2.6-5,500 ng/ml) correlates well (rs = 0.95, P less than 0.001) with the in vivo number of IgE molecules/basophil (6,000-600,000). The total number of IgE receptors/basophil was monitored by incubating them with an IgE-rich serum (15 microgram/ml), quantitatively stripping IgE from the cells at pH 3.7, and measuring e...

Eosinophils Express Low Levels of High Affinity IgE Receptor Transgenic Mouse Human Eosinophils and Human High

Uncoupling of Natural IgE Production and CD23 Surface Expression Levels

CD23, the low affinity receptor for immunoglobulin E (IgE), has been proposed to play a critical role in the regulation of IgE production, based on altered IgE levels in CD23-deficient mice and transgenic mouse models, as well as in mouse strains with mutations in the CD23 gene, e.g. 129 substrains. Here, we have investigated a mouse line termed LxT1 that expresses reduced CD23 surface levels o...

Human neurocysticercosis. IgE in cerebrospinal fluid.

The detection of IgE is technically difficult because of its reduced concentrations in serum, and even lower concentrations in cerebrospinal fluid (CSF). In the present investigation we studied 86 CSF samples using an immunoenzymatic method with an anti-IgE-alkaline phosphatase conjugate and a fluorigenic substrate. The samples were from three groups: A) 29 patients with neurocysticercosis (NC)...

Biology of IgE production: IgE cell differentiation and the memory of IgE responses.

The generation of long-lived plasma cells and memory B cells producing high-affinity antibodies depends on the maturation of B cell responses in germinal centers. These processes are essential for long-lasting antibody-mediated protection against infections. IgE antibodies are important for defense against parasites and toxins and can also mediate anti-tumor immunity. However, high-affinity IgE...
