Figure 4. Apparent discrepancy between functional parameters. Correlation analysis of functional parameters measured following Ag-specific stimulation of Melan-A-specific cells isolated from either PBMC (open circles) or TILN (closed triangles). (A) CD107a vs. IFNγ. (B) IFNγ vs. % specific lysis. (C) CD107a vs. % specific lysis. The outliers highlighted in gray have been excluded from the statistical analysis of CD107a vs. % specific lysis, as they had very low lytic capacity.
