Recurrent pregnancy loss is associated with anti-phospholipid antibodies (aPL), in particular in women with anti-phospholipid syndrome. aPL are a large family of autoantibodies, directed against phospholipids and phospholipid-binding proteins (e.g., prothrombin and beta2-glycoprotein I). Although the association between aPL and recurrent pregnancy loss is well documented, little is known about which aPL subset is responsible. To address this, we characterized a panel of six murine monoclonal aPL, which were subsequently administered to pregnant mice via passive transfer. While both anti-beta2GPI antibodies evaluated caused significant increase in fetal resorption, the effects of anti-PT antibodies varied from no effect to increased pregnancy loss. Similarly, neither lupus anticoagulant activity nor murine cross-reactivity predetermined aPL pathogenicity. We conclude that there is no obvious common reactivity between the aPL capable of increasing pregnancy loss, suggesting that a combination of reactivities, rather than one aPL specificity in particular, may lead to aPL-mediated pregnancy loss.
