To answer this question, we first cultured Daudi cells, a Burkitt’s lymphoma known to be a target for Vδ2 T cell cytotoxicity, with purified γδ T cells at different ratios (to select the best ratio) and the cytotoxic activity of Vδ2 T cells was evaluated by analyzing membrane Annexin V ligation on apoptotic Daudi cells by flow cytometry. This evidence concerns the gene ANXA5 and Burkitt lymphoma.
