Fourth International Workshop on immunology of pre-eclampsia, December 2004, Reunion, France.

摘要

The Fourth International Workshop on 'Reproductive Immunology, Immunological Tolerance and Immunology of Pre-eclampsia' was held in the Island of La Reunion in December 2004. Besides intense sharing of immunological data, it included also epidemiological studies from South Africa, USA and Australia, as well as genetic studies from South Africa and Mauritius, discussions on the future of graft transplant tolerance, implications of inositol-phosphoglycans in the pathogenesis of pre-eclampsia (PE), pathways to the inflammatory syndrome and other topics. Participants shared the belief that we may be witnessing significant steps forward in our comprehension of PE as an immunological event, with a prominent role for deregulation of the innate immune system, probably controlled by T cells and cytokine networks at the feto-placental interface. There was a growing consensus for an NK cell (KIR)-dependent event, with regulation exerted by T cells, as well as an important role for HLA-C presentation/recognition and HLA-G in mediating inflammatory cytokine imbalance, with an emphasis on IL-12 and IL-16 It is hoped that the next Workshop in 2006 will prove the immune involvement by dissecting the NK/Treg/Ts cell and HLA-CI HLA-G circuits leading to cytokine and vascular dysfunction.
