Figure Lengend Snippet: Increased Vδ2 T cell cytolytic function against cancer cell lines in overnight cocultures (A) Comparison of cytotoxic function by flow cytometry against cancer cell lines K562, H1299, A2780, MCF7, and T47D and (B) difference in cytotoxicity of Vδ2 T cells from eight donors expanded with either ALN+IL-2 or ALN+IL-2+IL-12+CD137L. Intracellular production of GzmB in (C) total (D) CD16 + and (E) NKG2A + Vδ2 T cells and frequency of (F) CD16 and (G) NKG2A expression upon coculture of different cancer cell lines with Vδ2 T cells expanded with ALN+IL-2 (dark gray) or ALN+IL-2+IL-12+CD137L (light gray). Wilcoxon matched-pairs signed-rank tests. ns, not significant. Circles represent cancer cell lines cultured alone, and cocultures with Vδ2 T cells expanded with IL-2 are shown with triangles and those expanded with IL-2+IL-12+CD137L with squares. (H) Production of cytolytic molecules in the supernatant upon coculture.
