Tissue and cellular distribution of an adhesion molecule in the carcinoembryonic antigen family that serves as a receptor for mouse hepatitis virus.

Abstract

Bgp1 proteins are present on BALB/c and SJL/J epithelia and endothelia. These glycoproteins might be involved in cell-to-cell contacts, for example between hepatocytes. On BALB/c mice, Bgp1a expression is consistent with the tropism of MHV-A59 for the liver. However, Bgp1a was also expressed on cells that were not infected by MHV-A59.
