    About the Special Issue

    From the Medawar paradox of "non rejection of the foetal allograft" by Sir Peter Medawar and early work of Freund on gamete autoimmunity, Immunology of Reproduction has massively evolved, with its failures (human anti HcG contraceptive vaccines) to present management of uterine cytokines allowing in Assisted Reproductive technology women with repeated implantation failures to obtain a greater success of pregnancy when they are properly treated than normal classical intercourse in healthy  women. Among the conceptual revolutions is the fact that Natural Killer cells, viewed in the 80s as a  threat to the foe to placental unit, which indeed can behave in pathological situations. As far as uterine NK cells are concerned, they are NECESSARY for successful pregnancy and secreting angiogenic factors. This issue will explore physiology and pathology of Human Reproduction, including pre-eclampsia which now is demonstrated to be a paternal specific immune deregulation of the "recognition" of the foe to placental unit. After a general introduction on the key steps of evolution of our concepts, totally unexpected in the 80s, we will examine each topic step by step.

    We believe such a survey, which we will request to be as accessible as possible to foreigners to the field, will fascinate immunologists and remind them that surprisingly, as human primates, without the circuits we will describe, …. they would not be there, and that in this respect immunology now appears physiologically as important as endocrinology in reproduction.
