Expression of the nonclassical HLA class I antigen, HLA-G, is associated with immune tolerance in view of its role in maintaining the fetus in utero, allowing tumor escape, and favoring graft acceptance. Expressed on invasive trophoblast cells, HLA-G molecules bind inhibitory receptors on maternal T lymphocytes and NK cells, thereby blocking their cytolytic activities and protecting the fetus f...

Mesenchymal stem cells (MSCs) are multipotent progenitor that reported to be immune-privileged and immune-evasive. MSCs capable of differentiating into specific cell types for subsequent use in cell-based therapy. They express low levels human leucocyte antigen (HLA)-ABC no HLA-DR. Wharton’s jelly-derived (WJ-MSCs) were also found leukocyte G (HLA-G), which renders them immunosuppressive. This ...

BACKGROUND The downregulation of blood monocyte HLA-DR expression also occurs in tissue infiltrative cells in a context of acute clinical inflammation, especially sepsis. This context favors the development of secondary infections and results from various mechanisms. Little is known about HLA-DR expression on bone marrow (BM) cells of the monocyte lineage, the source of circulating monocytes. T...

We have investigated the role of antigen-processing machinery (APM) component defects in HLA class I antigen downregulation in laryngeal squamous cell carcinoma (SCC) lesions and assessed the clinical significance of these defects. To this end, 63 formalin-fixed, paraffin-embedded tumor lesions were examined for APM component and HLA class I antigen expression by immunohistochemistry. Calnexin,...

Abstract Immunotherapeutic approaches in cancer aim to booster T cell mediated immune responses. Tumor-specific cells recognize target via human leukocyte antigen (HLA) molecules before specific lysis is initiated. Malignant gliomas are known for their immunoevasive and immunosuppressive properties which impede effective tumor-specific responses, including clinical responses checkpoint inhibiti...

Background: Research says that diabetes may develop in over 10% of non-diabetic pregnant women. Diabetes which generally occurs late in second trimester and third trimester of pregnancy, it is called gestational diabetes. Overweight or suffering from obesity before pregnancy is type 2 diabetes risk factor. In most cases, diabetic symptoms disappear after delivery. HLA-G has an important role bo...

This research topic gathered several researchers who actively base their research and investigations on the non-classical HLA-G molecule. HLA-G differs from classical HLA class I molecules since it has limited protein variability, can be expressed in several membrane-bound and soluble isoforms generated by alternative splicing generating, and modulates immune response. HLA-G expression is physi...

Introduction . Multiple myeloma (MM) is a B-cell malignancy with clonal expansion of plasma cells in bone marrow. Highdose chemotherapy autologous haematopoietic stem cell transplantation among main consolidation therapies MM. Myeloid-derived suppressor (MDSCs) are immature myeloid-accompanying able to suppress the immune response. The administration granulocyte colony stimulating factor (G-CSF...
