Figure 1From: A phase I study of dexosome immunotherapy in patients with advanced non-small cell lung cancerCytolytic activity of NK cells. Cytolytic activity of NK cells isolated from the PBMC of 4 patients (DU05, DU08, DU24, DU50) pre (squares) and post (circles) immunization and cultured with (dark shapes) or without (open shapes) IL-2 was determined. The percentage lysis of the NK target (K562) cells is reported at effector to target ratios of 0.2:1 to 25:1.Back to article page
