title: Fetuin. In vitro effect on sheep erythrocyte rosette formation with human T lymphocytes.
abstract: Peripheral blood lymphocytes from six healthy control subjects were incubated in vitro with fetuin and enumerated for sheep erythrocyte rosette forming T cells. Significant enhancement of rosette-forming T lymphocytes was observed in a dose-related manner. The physical presence of fetuin is not required for this effect. Incubation of lymphocytes with human AB serum has no significant effect on the rosette formation. This enhancing effect of fetuin appears to be secondary to alteration in T lymphocyte surface receptors for sheep erythrocytes.
