Outline of Final Research Achievements

We demonstrated novel regulatory mechanisms by which bovine IFNTs were regulated by transcriptional factors TEAD2, TEAD4 and YAP1. In addition, two IFNTs, IFNT2 and IFN-tau-c1, were regulated by different transcription factors. In this study, IFNT up-regulated immune- and antigen presentation-related genes in bovine endometrium, indicating that IFNT regulated immune system against conceptus in pre-implantation endometrium.
We identified that conceptus-derived exosome exists in bovine and ovine endometrial lumen, and its components differed during peri-implatantion periods. We further indicated that conceptus-derived exosome regulated endometrial condition essential for the conceptus implantation in pre-implantation periods.
