The human leukocyte antigen-G (HLA-G) is considered an immune checkpoint molecule involved in tumor immune evasion. Hypoxia and the metabolic sensor hypoxia-inducible factor 1 (HIF-1) are hallmarks of metastasization, angiogenesis, and intense tumor metabolic activity. The purpose of this review was to examine original in vitro studies carried out in human cancer cell lines, which reported data...

Human leukocyte antigen (HLA)-G, which is mainly expressed at the maternal-fetal interface, may play a role in the immune tolerance of the semi-allogenic fetus by the mother. Functional studies have shown that HLA-G is indeed a potential modulator of different immune responses. Therefore, it is of interest to study the level of expression of soluble HLA-G in several biological fluids derived fr...

The non-classical major histocompatibility complex class I molecule HLA-G is expressed mainly by extravillous trophoblasts at the materno-foetal interface. HLA-G has been found to bind endogenously processed nonameric peptides but its function as a restriction element for a cytotoxic T cell response to viruses with tropism for trophoblastic cells has never been demonstrated. In this study, cand...

HLA-G has been documented both in establishment of anti-tumour immune responses and in tumour evasion. To investigate the clinical relevance of HLA-G in non-small-cell lung cancer (NSCLC), expression status and potential significance of HLA-G in NSCLC were analysed. In this study, HLA-G expression in 101 NSCLC primary lesions and plasma soluble HLA-G (sHLA-G) from 91 patients were analysed with...

Human leucocyte antigen-G (HLA-G) plays a key role in maternal-foetal tolerance and allotransplantation acceptance and is also implicated in tumour escape from the immune system. The modulation of HLA-G expression can prove to be very important to therapeutic goals in some pregnancy complications, transplantation, cancer and possibly autoimmune diseases. In spite of substantial similarities wit...

background and purpose: hila-g is an immunomodulatory molecule and alteration of its expression is prevalent during viral infections. hla-g expression in hiv-positive patients has been inconsistent between different studies and some suggest that interleukin-10 (il-10) influences the expression of hla-g. the aim of this research was to investigate the expression of il-10 in hiv-positive patients...

The human leukocyte antigen G (HLA-G) molecule exhibits limited tissue distribution and exerts multiple immunoregulatory functions. Recent studies indicate an ectopic up-regulation in tumor cells that may favor their escape from antitumor immune responses. The role of HLA-G in B-cell chronic lymphocytic leukemia (B-CLL) has not been defined. HLA-G expression was studied retrospectively in circu...

Background and Aims: In this study, the effect of rs310441 polymorphism in the human leukocyte antigen (HLA) region on the development of susceptibility or resistance to Type 1 diabetes (T1D) among the people with T1D compared to healthy subjects has been investigated. Materials and Methods: This research, which is based on the examination of 130 cases with T1D and 98 controls, has been carrie...

Considering the well established role of nonclassical HLA-G class I molecules in inhibiting natural killer (NK) cell function, the consequence of abnormal HLA-G expression in malignant cells should be the escape of tumors from immunosurveillance. To examine this hypothesis, we analyzed HLA-G expression and NK sensitivity in human malignant melanoma cells. Our analysis of three melanoma cell lin...
