Ex vivo expansion of tumor-infiltrating lymphocytes from nasopharyngeal carcinoma patients for adoptive immunotherapy
摘要
Abstract
Establishing Epstein-Barr virus (EBV)-specific cytolytic T lymphocytes (EBV-CTLs) from peripheral blood mononuclear cells (PBMCs) for adoptive immunotherapy has been reported in EBV-associated malignancies including Hodgkin's lymphoma and nasopharyngeal carcinoma (NPC).In the current study,we performed ex vivo expansion of tumor-infiltrating lymphocytes (TILs) obtained from NPC biopsy specimens with a rapid expansion protocol using anti-CD3 monoclonal antibody (OKT3),recombinanthuman interleukin (IL)-2,and irradiated PBMCs from healthy donors to initiate the growth of TILs.Young TIL cultures comprised of more than 90% of CD3+ T cells,a variable percentage of CD3+CD8+ and CD3+CD4+ T cells,and less than 10% of CD3-CD16+ natural killer cells,a similar phenotype of EBV-CTL cultures from PBMCs.Interestingly,TIL cultures secreted high levels of the Th1 cytokines,interferon gamma (IFNγ) and tumor necrosis factor-alpha (TNF-α),and low levels of the Th2 cytokines,IL-4 and IL10.Moreover,young TILs could recognize autologous EBV-transformed B lymphoblast cell lines,but not autologous EBV-negative blast cells or allogeneic EBV-negative tumor cells.Taken together,these data suggest that ex vivo expansion of TILs from NPC biopsy tissue is an appealing alternative method to establish T cell-based immunotherapy for NPC.关键词
