Description | Although the role of the non-classical human leukocyte antigen E (HLA-E) was originally thought to be limited to the development of a maternal tolerance to a semiallogeneic fetal graft, it is now known that HLA-E exerts multiple immunoregulatory functions. The significance of the presence of HLA-E in neoplastic cells and/or backround microenvironment cells in classical Hodgkin lymphoma (cHL) is not well characterized. In our study, we evaluated the presence of HLA-E in both neoplastic and background cells in 40 cases of cHL. We found HLA-E in both neoplastic and background cells. There was a positive statistical correlation between the expression of HLA-E in neoplastic cells and the clinical stage of the disease, which indicates an immune-tolerogenic property of this multiple-purpose molecule. The presence of HLA-E in background cells seems to be prognostically neutral but its significance still needs to be determined. The mechanisms regulating the immunopathology of cHL neoplastic cells with respect to the presence of these molecule deserve further studies. |
