[Trophoblastic interferons and embryonal immune tolerance].
Current evidence support the hypothesis that trophoblast interferons play a key role in preventing maternal immunologal rejection of the embryonic semi-allograft. The information of this review is divided in two sections. In the first section we described molecular and biological characteristics of type I (alpha, beta, omega, tau and spl) and type II (gamma) interferons. In the second section we emphasize studies on immunoendocrine functions of IFN-tau (oTP-1 or trophoblastins) in the network of cytokines and hormonal environment at the uterine embryonic interface.
