Access through your institution Buy or subscribe Deregulation of B-cell proliferation may induce malignant growth causing various lymphoproliferative disorders including the most prevalent


hematological malignancies in adult, namely lymphoma, multiple myeloma (MM) and B-cell chronic lymphocytic leukemia.1 Inducing depletion through an apoptotic pathway or inhibiting B-cell


proliferation and differentiation constitutes a rational approach to cure B-cell-mediated disorders. One such modality used recently in B-cell malignancies is rituximab, a B-cell-depleting


monoclonal antibody against CD20.2 Nevertheless, efforts to identify novel therapeutic targets remain essential. Like NK, T and antigen-presenting cells, B cells express immunoreceptor


tyrosine-based inhibitory motif bearing receptors such as the leukocyte immunoglobulin-like receptor LILRB1/ILT2/CD85j.3 ILT2 is characterized by a broad specificity for HLA class-I


molecules, with the highest affinity for HLA-G. However, no information is currently available on the role of ILT2 and HLA-G in regulating neoplastic B-cell growth. The biological functions


of HLA-G have been originally described in maternal-fetal tolerance and more recently in allograft acceptance and tumor escape showing evidences for its tolerogenic properties.4 In contrast


to classical HLA-class I, HLA-G is expressed in a limited number of healthy tissues and can be expressed as seven isoforms including four membrane-bound (HLA-G1–HLA-G4) and three soluble


(HLA-G5–HLA-G7) proteins.4 This is a preview of subscription content, access via your institution ACCESS OPTIONS Access through your institution Subscribe to this journal Receive 12 print
