CD14

Methodology: IHC

Clinical Significance:
The expression of CD14 by IHC is a useful biomarker for distinguishing neoplasms of monocytic and Langerhans cell origin from other hematolymphoid neoplasms. CD14 is a glycoprotein expressed on mature monocytes, histiocytes/macrophages, Langerhans cells, and to a lesser degree on neutrophils, and is a receptor for bacterial lipopolysaccharide (LPS), thus functioning as an opsonic receptor to facilitate phagocytic uptake.
