Abstract: B7-H6,a newly discovered member of the immunoglobulin superfamily,is the membrane-binding ligand of NKP30,which is an activated receptor of the NK cell surface.B7-H6 is specifically expressed in various tumor tissues,and its expression is significantly correlated with various clinicopathological parameters and prognosis.The tumor cell ectodomain shedding of B7-H6 forms soluble B7-H6(sB7-H6),which down-regulates NKp30-mediated NK cell cytotoxicity and cytokine secretion.Studies have found that B7-H6 promotes tumorigenesis via protease inhibitors,Myc,abnormal immune response,proliferation,and anti-apoptosis.At present,the intervention therapy of the B7-H6 gene is a new tumor treatment strategy,and related immunotherapy is being explored.In summary,B7-H6 has been proved to be a potential biomarker and valuable therapeutic target for the diagnosis,treatment,prognostic evaluation of cancer.

Key words: B7-H6, sB7-H6, NKP30, Tumor immunity, Immunotherapy
