| Background Information | CD23 (FcεRII, BLAST-2), the low affinity IgE receptor, is a 45 kDa type II membrane glycoprotein expressed on eosinophils, follicular dendritic cells, Langerhans cells, mature B cells (mainly upon activation), EBV-transformed lymphoblasts, monocytes, and subpopulation of platelets. CD23 mediates IgE-dependent cytotoxicity by eosinophils and macrophages, and downregulates IgE secretion in response to high levels of IgE, involving release of pro-inflammatory cytokines. |
