title: Novel rosette formation of murine spleen cells with autologous red blood cells.
abstract: Spleen cells of normal BALB/c mice formed rosettes with autologous red blood cells, and the formation was calcium ion dependent. Peritoneal exudate cells, bone marrow cells and thymocytes did not form such rosettes. Spleen cells were passed over a Sephadex G-10 column or incubated on a plastic surface in order to eliminate adherent cells from them. Cells obtained by both these methods were unable to form rosettes. B cell-, T cell- and natural killer cell-enriched fractions in spleen cells were unable to form rosettes either. Some of the mouse IgG subclasses suppressed rosette formation when added to its site. These are monoclonal antibodies whose specificities are directed against Aspergillus niger glucose oxidase. Moreover, Aspergillus niger glucose oxidase suppressed the rosette formation when spleen cells had been treated with it as well as when it had been added to the site of rosette formation. These findings suggest that some murine spleen cells have receptors to a structure on autologous red blood cells, which is recognized by an anti-Aspergillus niger glucose oxidase monoclonal antibody.
