Immunohistochemistry: HLA G Antibody (MEM-G/1) - BSA Free [NB500-302] - ELA affects first trimester placental explant trophoblast proliferation. (a) HLA-G immunostaining (brown color top panel) indicates the location of extravillous trophoblasts. PhosphoH3(Ser10) immunostaining (brown color lower 3 panels) identifies proliferating cells undergoing mitosis. In extravillous trophoblasts of explants treated with ELA proliferation appears to decrease. In control explants almost all villous cytotrophoblasts proliferate, while this is much less apparent in explants treated with ELA. Treatment with ELA in combination with ML221 does not return villous cytotrophoblast proliferation to the level as seen in control explants. (b) Quantifying the percentage of proliferating extravillous trophoblasts observed by immunohistochemistry shows a significant decrease upon treatment with ELA which cannot be rescued by the addition of ML221. P = 0.08 between controls & explants treated with ELA & ML221. n = 12 placentas, 5 explants per treatment. Bars represent mean ± SEM & data was tested with one-way ANOVA followed by Bonferroni multiple comparisons test. *Indicates p < 0.05. (c) Treatment of explants with an ELA neutralizing antibody shows a significant increase of extravillous trophoblast proliferation upon quantifying immunohistochemistry stainings. n = 4 placentas, 5 explants per treatment. Bars represent mean ± SEM & data was tested with a Student’s t-test. *Indicates p < 0.05.

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).
