title: HLA-G in the human placenta: expression and potential functions.
abstract: HLA-G is a non-classical class I molecule specifically expressed in the placenta, suggesting that it might have a physiological function at the materno-foetal interface. The structural characteristics of HLA-G, the placental pattern of expression and the functional properties of this class Ib glycoprotein in vitro are described and evaluated in the context of pregnancy. The possible anti-viral function of HLA-G, its modulatory role of natural killer cell activity and its likely non-immunological functions are discussed.
