Abstract
Human leukocyte antigen G (HLA-G) is a nonclassical major histocompatibility complex (MHC) molecule class I expressed in immune-privileged sites and plays an essential role in the development of maternal tolerance to genetically different fetal tissues. It was described for the first time with its clinical applications by Edgardo D. Carosella and his team at the Saint-Louis Hospital. It is predominantly expressed by the cytotrophoblast, while ectopic expression is observed in certain situations, such as tumor cells. In light of the well documented immunotolerant function of HLA-G, we will focus on the role of this molecule in the escape of tumor cells from different immune cells, its expression in cancers of distinct histology and the use of soluble HLA-G in diagnosis or as pronostic factor in order to detect tumors and to control disease stage, furthermore its use as a novel therapeutic target in cancer.
Résumé
HLA-G est une molécule du complexe majeur d’histocompatibilité (CMH) non classique de classe I exprimée sur des sites immuno-privilégiés et joue un rôle essentiel dans le développement de la tolérance maternelle vis-à-vis des différents tissus foetaux. Elle a été décrite pour la première fois avec ses applications cliniques par Edgardo D. Carosella et son équipe à l’hôpital Saint-Louis. Son expression est prédominante par le cytotrophoblaste, tandis que l’expression ectopique est observée dans certaines situations telles que les cellules tumorales. Compte tenu de la fonction d’immunotolérance de la molécule HLA-G la plus documentée, nous allons nous concentrer sur le rôle de cette molécule dans l’échappement des cellules tumorales aux différentes cellules immunitaires, son expression dans les différents types de cancer et l’utilisation des molécules HLA-G solubles dans le diagnostic ou en tant que facteur pronostique afin de détecter les cellules tumorales et de contrôler le stade de la maladie, par ailleurs son utilisation comme une nouvelle cible thérapeutique dans le cancer.
