Ige Production

IgE production is the immune process that generates immunoglobulin E antibodies, which help defend against parasites but also drive many allergic diseases. After antigen exposure, B cells receive signals through CD40 and cytokines such as interleukin-4 or interleukin-13, causing class-switch recombination from another antibody class to IgE and differentiation into antibody-secreting plasma cells. Secreted IgE binds with high affinity to FcεRI receptors on mast cells and basophils, priming them for rapid mediator release when the antigen is encountered again. Understanding this pathway supports clinical research on allergy, asthma, anaphylaxis, immunodeficiency, and targeted therapies that reduce IgE-mediated inflammation.

In vitro analysis of class switch recombination in mice is challenging due to cytophilic IgE molecules bound to Fc receptors on the surface of B cells. We describe a method for IgE detection using trypsin-mediated cleavage of surface-bound IgE prior to fixation and permeabilization for cytoplasmic fluorescence staining.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs

0 Views •

2024

Asthma is a chronic respiratory condition for which new therapeutic avenues, including anti-inflammatory drugs like mast cell stabilizers and anti-IgE treatments, continue to be developed. Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

Development of an in vitro model system for studying the interaction of Equus caballus IgE with its high-affinity receptor FcεRI

The current study describes the development and applications of a genetically engineered assay system based on the transfection of rat basophilic leukemia cells with the equine FcεRIα gene. Transfected cells express a functional receptor where the release of mediators of the allergic response can be activated by IgE and antigen.
