A certain spectrum of HLA antigens is expressed in the migrating, invasive cytotrophoblast cells. As these cells drive toward the decidua, their expression of the HLA antigens changes dramatically. Precursor villous cytotrophoblast cells express only one HLA-G isoform, HLA-G5.HLA-G is highly expressed on blasts and tolerogenic dendritic cells in patients with acute myeloid leukemia. HLA-G belongs to the HLA class I heavy chain paralogues. This class I molecule is a heterodimer consisting of a heavy chain and a light chain (beta-2 microglobulin). The heavy chain is anchored in the membrane.
