NCR3LG1 and acute myeloid leukemia: Since the B7 family member B7H6 has been reported to be expressed on a broad range of different solid tumors as well as hematological neoplasia [18,19,21,22,23] but is not found on hematopoietic cells of healthy individuals and rarely expressed on normal tissues [18,19,21,31,32], we studied the expression of B7H6 in patient-derived AML samples compared to established AML cell lines in detail, both at mRNA and cell surface expression level.
