Decreased killer cell activity in preeclampsia
Anti-D antibody-dependent cellular cytotoxicity of peripheral blood mononuclear cells was measured against O, Rh (D)-positive erythrocytes in 20 healthy pregnant women (chosen from all trimesters), and in 16 toxemic patients; it was then compared to the cytotoxic activities of 20 women 3 months after parturition and to that of 42 nonpregnant women. The application of an enzyme-like kinetic model for measurement of maximal cytotoxic function has permitted sensitive determination of the K cell function. It was found that during normal pregnancy maternal K cell activity did not change, whereas it was significantly decreased in preeclampsia.
