[Human leukocyte antigen-G (HLA)-G as a biomarker in cancer]. / Antígeno leucocitario humano G (HLA-G) como biomarcador en cáncer.

Human leukocyte antigen is a class I HLA classic molecule that is preferentially expressed in cytotrophoblast cells and participates in tolerance and immune system suppression. The expression of HLA-G is induced in viral infections, autoimmune disorders, and cancers. Currently, HLA-G is considered a biomarker in the diagnosis, prognosis, and therapy of cancer.
