WebDue to this unique regulatory mechanism, ICS will falsely identify all effector memory cells (~20% of total T cells) as perforin-positive. Perhaps of greater significance is the Lysispot assay, a modified ELISpot capable of enumerating Ag-specific cytotoxic CD8+ T cell effector function through direct target cell lysis 20. WebAutologous T cells were transfected with a γ-retroviral vector encoding a CAR fusing human NKG2D with the CD3ζ signaling domain. Four dose levels (1x10e6-3x10e7 total viable T cells) were evaluated. Twelve subjects were infused (7 AML, 5 MM). NKG2D-CAR products demonstrated a median 75% vector-driven NKG2D expression on CD3+ T cells.
