title: Novel cell surface antigens expressed on mouse alveolar macrophages.
abstract: Two new cell surface antigens expressed on mouse alveolar macrophages were defined by rat monoclonal antibodies. One marker, AVM-1, was detected on mouse alveolar macrophages, but it was undetectable on resident peritoneal cells, thioglycollate medium-induced peritoneal cells, and splenic macrophages. Splenic lymphocytes, thymocytes and bone marrow cells were also AVM-1 negative. Anti-AVM-1 monoclonal antibody immunoprecipitated a single polypeptide with a molecular weight of 200,000. Of particular interest was the finding that the anti-AVM-1 antibody could inhibit the formation of EA and EAC rosette on macrophage line cells. A second antigen (AVM-2) was also present on alveolar macrophages, and its molecular weight was 38,000.
