Background: HLA-G
Discovered in cytotrophoblasts, HLA-G is involved in fetal maternal immune tolerance and some studies have linked its downregulation with severe preeclampsia (3). HLA-G mediated immune suppression works by impeding cell proliferation, differentiation, cytotoxicity, cytokine secretion and chemotaxis; and activation of regulatory cells and MDSCs or M2 type macrophage. HLA-G is constitutively expressed in immune-privileged sites such as pancreatic islets, mesenchymal stem cells (MSCs) and the cornea. Upregulation of HLA-G occurs in pathological states including cancer, allo-transplantations, viral infections, autoimmune and inflammatory diseases (4). In cancer, HLA-G expression is induced by hypoxia and has been correlated with advanced tumor stage, tumor metastasis, and poor therapeutic response and survival. HLA-G is an attractive tumor associated-antigen (TAA) for immunotherapy and is considered a major immune checkpoint (ICP).
