Low-Affinity Immunoglobulin E Receptor (CD23)

Target
CD23
Molecular classification
Type II transmembrane glycoprotein, C-type lectin, Receptor
01

Overview

CD23, the low-affinity IgE receptor (FcεRII), is a type II transmembrane glycoprotein that plays a crucial role in regulating IgE levels and mediating allergic responses. It is expressed on various immune cells, including B lymphocytes, macrophages, and eosinophils. CD23 binds to IgE and participates in antigen presentation, cell adhesion, and the modulation of immune signaling pathways. Due to its central role in allergic responses, CD23 is considered a promising target for therapeutic intervention strategies aimed at treating allergies or modulating humoral immunity.
