[HLA-G in organ transplantation].
The HLA-G molecule plays a crucial role in the protection of the fetus against aggression by the mother's immune system. Recently, it was shown that HLA-G was involved in the protection of the transplanted tissues, via the inhibition of all immune effectors that mediate graft rejection. The inhibitory functions of HLA-G were studied in vitro using allo- and xeno-geneic models, ex vivo on transplanted tissues biopsies, and in an in vivo animal model. In this review, we will summarize recent results which show that HLA-G acts as a regulator of immune function, seems to be directly involved in transplant acceptation, and should be taken into consideration when monitoring transplanted patients' status.
