Description

Rat Monoclonal Antibody

The eBio927 MAb reacts with PDCA-1 (BST2, CD317), a specific marker of plasmacytoid dendritic cells (pDC), also known as type I IFN-producing cells (IPC) in the naive mouse. Mouse IPCs are typically CD11c+, CD11b-, B220+, Ly-6C+, and CD62L+. PDCA-1 is predominantly expressed by IPCs in the naive mouse which represents a very minor population (<0.5%) of splenocytes. It is upregulated on numerous cell types following stimulation which triggers an IFN response. PDCA-1 cycles between cell surface and intracellular compartments and may function to regulate trafficking of secreted cytokines. PDCA-1 (BST2) is the protein recognized by antibody 120G8. The eBio927 MAb has also been shown to have functional activity. The epitope recognized by eBio927 is distinct from eBio129c; thus, the antibodies can be used to costain, purify and identify pDCs.

BST2 (CD317, HM1.24 antigen, DAMP-2, tetherin) is an integral membrane protein that is involved in the development and growth of B-cells. The surface expression of BST2 on fibroblast cell lines facilitated the stromal cell-dependent growth of DW34, a pre-B-cell line. BST2 is highly expressed during B-cell development, from pro-B precursors to plasma cells, T-cells, monocytes, NK cells and DCs (at protein level), and myeloma cells. Research studies have shown that BST2 also functions as an inhibitor of retrovirus release from human cells whose activity is antagonized by the HIV-1 accessory protein, Vpu. While BST2 causes retention of virions on cell surfaces or endocytosis into BST2-positive compartments, its depletion abolished the viral requirement for Vpu for virus release, an activity that may represent a potential therapeutic strategy for the treatment of HIV/AIDS. Another disease associated with BST2 dysfunction is stomatitis.
