干扰素-τ与反刍动物妊娠识别的研究

The Study of IFN-τ and Pregnancy Reognition in Ruminants

干扰素 -τ是由反刍动物孕体附植时发出的特有妊娠信号 ,是建立母体妊娠识别的一种主要因子。反刍动物早期妊娠识别和妊娠诊断是影响其繁殖力的关键因素。文章对干扰素 -τ的分子结构。

IFN τ is a primary factor secreted by the conceptus responsible for maternal recognition of pregnancy in ruminants.In ruminants,early pregnancy recognition and exact diagnosis of pregnancy id the key factor to affect maternal productivity.This review is about IFN τ molecular structure and biological function ,and summarily describle the latest achievement of molecular mechanism in pregnancy recognition in ruminants.
