Abstract
Pregnancy zone protein from pregnancy serum and control preparations from male serum were tested in lymphocyte transformation tests, in a system for rosette formation by T and B lymphocytes and in leucocyte migration inhibition tests using PPD-induced inhibition. PZ-protein preparations caused a dose dependent inhibition of lymphocyte transformation after stimulation with PHA, PPD and MLC. Inhibition was most pronounced in the PHA-system. In the rosette tests there was a tendency for T lymphocytes to bind fewer SRBC after incubation with PZ-protein while no effect on B rosettes was observed. In contrast, PPD-induced inhibition of leucocyte migration was abrogated effectively by PZ-protein, but not by corresponding fractions from male serum.
