During the bovine peri-implantation period, immune cells are exposed to endocrine and paracrine signals, which support feto-placental development. Recent studies in cattle have shown that the antiviral factor Mx2, known to be up-regulated by conceptus-derived interferon-τ in pregnancy, is detected in peripheral blood mononuclear cells (PBMC) and can be used ...
