CD23 is a 45kD protein, also known as Leu-20, FcERII, IgE Fc receptor, BLAST-2, B6, and low affinity IgE receptor.
It is a member of the Ig family, expressed on most mature B cells, B cells in follicular mantle (but not in proliferating germinal center cells, follicular dendritic cells, monocytes, eosinophils, Langerhans cells, and a subset of T cells (10-15% of tonsillar T cells).
CD23 responds to high levels of IgE by downregulating IgE secretion.
In human monocytes, CD23 triggering results in release of pro-inflammatory cytokines including TNF-a, IL-1, IL-6, and GM-CSF.
CD23 can be proteolytically cleaved to generate soluble CD23 fragments of various molecular weights.
In chronic lymphocytic leukemia, levels of soluble CD23 in the serum can be used as a prognostic marker to identify patients at high risk for disease progression.
Alternate splicing of exon 2 can also generate two cell-surface isoforms of CD23 differing by 6aa in their cytoplasmic region.
