Lysosomal-membrane-associated glycoproteins (Lamps) 1 and 2 are rarely found on the plasma membranes of normal cells. There is evidence suggesting an increase in their cell-surface expression in tumor cells, with some data indicating that the adhesion of some cancer cells to the extracellular matrix is partly mediated by interactions between Lamps and(More)
From two independent fusions, fifteen MAbs directed to the F protein of the bovine respiratory syncytial virus (BRSV) were characterized by radioimmunoprecipitation assays. Competition binding assays among these MAbs identified two distinct antigenic sites (A and B) and one overlapping site (AB). All of the MAbs specific to epitopes belonging to site A(More)
The immune response of calves was studied following infection with non-cell-passaged Bovine respiratory syncytial virus (BRSV). Two groups of 6 specific pathogen free (SPF) calves were housed in separate isolation rooms. One group was inoculated intranasally with a non-cell-passaged BRSV strain and the control group was mock-infected. A BRSV specific(More)
Bovine respiratory syncytial virus (BRSV) is a major cause of respiratory disease in calves. The BRSV genome encodes two major glycoproteins, G and F, which are the major targets for the host antibody response. We have expressed the F glycoprotein in insect cells (Sf9) using a recombinant baculovirus vector. A comparison of the F protein expressed in(More)
