Figure 4: NKG2D-ligand expression and soluble ligands.
A) Surface NKG2D ligand detection in AML blasts (7 AML patients) and MM cells (3 MM patients) in bone marrow aspirates (BMA) at baseline measured by flow cytometry (SFI>1 indicates ligand expression exceeding isotype). AML blasts: live/CD45dim cells expressing patient-specific AML markers including CD117, CD123, CD33, and HLA-DR. MM cells: live/CD138+CD38+ cells. B) Detection of soluble MICA and MICB in patient plasma at baseline using ELISA. Plasma of Patient 3 (MM) was separately spiked with soluble MICA and MICB as an internal positive control. ND: not detectable.
