HLA-G is a non-classical major histocompatibility complex (MHC) class I molecule encoded within the human leukocyte antigen (HLA) region. Unlike classical MHC class I proteins, HLA-G has limited polymorphism and a restricted tissue distribution, primarily expressed at the maternal–fetal interface, where it plays a critical role in immune tolerance during pregnancy.
Structurally, HLA-G consists of a heavy chain associated with β2-microglobulin and presents peptides similarly to other MHC class I molecules. However, alternative splicing generates multiple isoforms, including both membrane-bound (e.g., HLA-G1) and soluble forms (e.g., HLA-G5). These structural variants contribute to its diverse immunomodulatory functions.
HLA-G interacts with inhibitory receptors such as ILT2 (LILRB1), ILT4 (LILRB2), and KIR2DL4 expressed on immune cells including natural killer (NK) cells, T cells, and antigen-presenting cells. Through these ligand–receptor interactions, HLA-G suppresses immune responses by inhibiting cytotoxic activity, reducing cytokine production, and promoting regulatory cell phenotypes.
In disease contexts, aberrant expression of HLA-G has been associated with cancer, viral infections, and autoimmune disorders. Many tumors exploit HLA-G expression to evade immune surveillance, leading to poorer clinical outcomes. Conversely, reduced HLA-G expression may contribute to pregnancy complications such as preeclampsia or recurrent miscarriage.
Therapeutically, HLA-G represents a promising target in both immunosuppression and immuno-oncology. Enhancing HLA-G activity could be beneficial in transplantation and autoimmune diseases by promoting immune tolerance. In contrast, blocking HLA-G or its receptors is being explored as a strategy to restore anti-tumor immunity. Ongoing research aims to better understand its mechanisms and develop targeted therapies that modulate HLA-G pathways.
