title: Human extravillous trophoblast MHC class I expression is resistant to regulation by interferon-alpha.
abstract: We have shown that MHC Class I antigen expression by first trimester human extravillous trophoblast cells is resistant to upregulation by IFN-alpha while embryonic fibroblasts of the same gestational age are responsive. This is in contrast to our previous finding that IFN-gamma increases both Class I mRNA and surface expression in these trophoblast cells. It would appear that human trophoblast has differential susceptibility to the effects of the two classes of IFN.
