Background

CD27; also known as TNFRSF7; is a member of the TNF-receptor superfamily limited to cells of the lymphoid lineage; and exists as both a dimeric glycoprotein on the cell surface and as a soluble protein in serum. As a type I transmembrane glycoprotein of about 55 kDa existing as disulfide-linked homodimer; CD27 has been shown to play roles in lymphoid proliferation; differentiation; and apoptosis.It has important role in generation of T cell immunity; and is an apparently robust marker for normal memory B cells. It is a T and B cell co-stimulatory molecule; the activity of CD27 is governed by its TNF-like ligand CD70 on lymphocytes and dendritic cells. The CD27-CD70 interaction is required for Th1 generation responses to differentiation signals and long-term maintenance of T cell immunity; and meanwhile; plays a key role in regulating B-cell differentiation; activation and immunoglobulin synthesis.
