    Background

    HLA class I histocompatibility antigen, alpha chain F (HLA-F) is a nonclassical member of the HLA class I family and has less genetic diversity than classical HLA molecules (1-4). HLA-F expression is primarily intracellular but has been observed on the surface in some contexts, including some activated immune cell subsets, virus-infected cells, invasive extravillous cytotrophoblasts, and various cancer types (5,6). HLA-F can be expressed on the surface as an open conformer monomer or dimer, or in a complex with β2-microglobulin and peptide. As an open conformer monomer, HLA-F is observed to interact with activating KIR3DS1 and inhibitory KIR3DL2 (7,8). The HLA-F/β2-microglobulin peptide complex interacts with inhibitory receptors ILT2 and ILT4 (9,10). It is hypothesized that high surface expression of HLA-F in tumors can be a mechanism of immune escape through interaction with inhibitory receptors on immune cells (5). In the context of viral infection, HLA-F interaction with activating KIR3DS1 on natural killer (NK) cells can result in NK cell degranulation and cytokine production (7).
