Background	HLA-E (human leucocyte antigen-E) is a conserved class I major histocompatibility molecule. It binds to the leader peptide derived from the polymorphic classical MHC molecules HLA-A, HLA-B and HLA-C. This peptide binding stabilizes the HLA-E protein and allows it to migrate to the cell surface. HLA-E then interacts with CD94/NKG2A receptors on natural killer cells. This interaction inhibits natural killer cell-mediated lysis of cells displaying HLA-E. In virally infected or tumor cells, down-regulation of HLA-A, HLA-B and HLA-C production prevents stabilization of HLA-E by the leader peptide. Under these circumstances, HLA-E is degraded before it reaches the cell surface and the cell is then vulnerable to lysis by natural killer cells.
