The roles of BST-2 in murine B cell development and on virus propagation
© 2023 The Societies and John Wiley & Sons Australia, Ltd..
The bone marrow (BM) stromal cell antigen-2 (BST-2), also known as tetherin, CD317, PDCA-1, or HM1.24, is a membrane protein overexpressed in several types of tumors and may act as a promising target for cancer treatment via antibody-dependent cellular cytotoxicity. BST-2 is also expressed in human BM stromal cells (BMSC), which support B cell development. While the activity of BST-2 as an antiviral factor has been demonstrated, the expression patterns and the role of BST-2 on B-cell development and activation have not been investigated, especially in vivo. In this study, Bst2 knockout (Bst2-/- ) mice were generated to assess the role of BST-2 on B cell development and activation. It was observed that BST-2 was not expressed in BMSC or all B cell progenitors even in wild-type mice and does not play a significant role in B cell development. In addition, the loss of BST-2 had no effect on B cell activation. Furthermore and in contrast to the well-known antiviral role of BST-2, infection of vesicular stomatitis Indiana virus to the BM cells collected from the Bst2-/- mice produced less infectious virus compared with that from the WT mice. These results suggest that murine BST-2 is different from human BST-2 in the expression pattern, physiological function, in vivo, and might possess positive role on VSV replication.
