PBMCs isolated from blood collected from macaques pre-vaccination and 4 weeks post-vaccination were co-cultured with ZA-pre-treated or untreated tumour cell lines for 4 h in the presence of Brefeldin A, monensin, and anti-CD107b as previously described for in vitro-expanded human Vδ2+ cells. This evidence concerns the gene LAMP2 and neoplasm.
