Like other immune checkpoints, inter- and even intratumor heterogeneity of HLA-G could render a rather complexity for HLA-G-target immunotherapy. However, little ... HLA-G is expressed on fetal derived placental cells. The heavy chain is approximately 45 kDa and its gene contains 8 exons. Exon one encodes the leader peptide, exons 2 and 3 encode the alpha1 and alpha2 domain, which both bind the peptide, exon 4 encodes the alpha3 domain, exon 5 encodes the transmembrane region, and exon 6 encodes the ...

Abstract. Human leukocyte antigen G (HLA-G), known as a central protein in providing immune tolerance to the fetus in pregnant women, is also studied for a possible role in tumor development. Many studies have claimed HLA-G as a new immune checkpoint in cancer. Therefore, HLA-G and its receptors might be targets for immune checkpoint …HLA-G is known to modulate the immune system activity in tissues where physiological immune-tolerance is necessary (i.e., maternal-fetal interface, thymus, and cornea). However, the frequent neo-expression of HLA-G in many cancer types has been previously and extensively described and is correlated with a bad prognosis. Despite …Feb 3, 2022 · The non-classical human leukocyte antigen G (HLA-G) is a potent regulatory protein involved in the induction of immunological tolerance. This is based on the binding of membrane-bound as well as soluble HLA-G to inhibitory receptors expressed on various immune effector cells, in particular NK cells and T cells, leading to their attenuated functions.

Binding of HLA-G to ILT4 expressed by DCs led to a decreased antigen presentation, thereby disturbing communication between DCs and other immune cells. In addition, HLA-G was shown to induce apoptosis in CD8+ T cells and reduces proliferation of CD4+ T cells and B cells [12,76,77,78]. Thus, HLA-G can interfere in many different immunological ...Some class I MHC genes encode nonclassical MHC molecules, such as HLA-G (which may play a role in protecting the fetus from the maternal immune response) and HLA-E (which presents peptides to certain receptors on natural killer [NK] cells).The non-classical human leukocyte antigen G (HLA-G) is a potent regulatory protein involved in the induction of immunological tolerance.

HLA-G was originally found to ...

Background In recent years, many immunoregulatory functions have been ascribed to soluble HLA-G (sHLA-G). Since chemotaxis is crucial for an efficient immune response, we have investigated for the first time the effects of sHLA-G on chemokine receptor expression and function in different human T cell populations. …Local Info Bremen Duesseldorf Frankfurt/Main Hamburg - Company Headquarters Hamburg - Area Office Hamburg - Terminal CTA Munich Stuttgart Leipzig.

However, two groups reported that HLA‐G was an unfavorable prognosticator, 17 , 18 and one group reported that it was a favorable prognosticator. 19 In addition to HLA‐E and HLA‐G inhibition of NK cell activity, HLA‐E can inhibit immune response through mechanisms that include inhibition of CD8 + T cell cytolytic function 12 and ...Expression of HLA-G at the maternal-fetal interface. 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-G5.1 HLA-G. HLA-G is a non-classical HLA class I gene that encodes a molecule with tolerogenic properties ().This molecule shows restricted tissue expression pattern, and was initially observed in extravillous cytotrophoblasts, where it plays an important role in the maintenance of fetal-maternal immune tolerance (); it has also been observed in few healthy immune-privileged tissues, as cornea ...Human leukocyte antigen (HLA)-G is a nonclassical MHC Class I molecule, which was initially reported as a mediator of immune tolerance when expressed in extravillous trophoblast cells at the maternal-fetal interface.
