Regulatory T cells (Tregs) are a major obstacle to the establishment of effective cancer immunotherapy. As mediators of immune tolerance, they are a critical target for pre-conditioning for adoptive immunotherapy. Here, we show that pre-treatment with cyclophosphamide or agonistic anti-OX40 mAb augments the anti-tumor immune effect of adoptive CD8+ T cell therapy in a clinically relevant wild-t...
We have previously described an in vitro sensitization (IVS) procedure which enabled the generation of therapeutic T cells from tumor-hearing mice for adoptive immunotherapy. The procedure involved culture of tumor-draining lymph node (TDLN) cells with irradiated tumor in the presence of interleukin-2 (IL-2). The availability of many recombinant cytokines affords an opportunity to examine their...
background : nonmyeloablative chemotherapy followed by adoptive immunotherapy is an attractive strategy for depleting regulatory t cells in the host. however, its efficacy is transient. here, we aim to investigate whether cyclic chemoim- munotherapy has therapeutic efficacy against cancer. methods :we examined the efficacy of cyclic chemoimmunotherapy with cyclophos- phamide and adoptively tran...
Both nature and induced regulatory T (Treg) lymphocytes are potent regulators of autoimmune and allergic disorders. Defects in endogenous Treg cells have been reported in patients with allergic asthma, suggesting that disrupted Treg cell-mediated immunological regulation may play an important role in airway allergic inflammation. In order to determine whether adoptive transfer of induced Treg c...
Adoptive T cell therapy has proven to be beneficial in a number of tumor systems by targeting the relevant tumor antigen. The tumor antigen targeted in our model is Mammaglobin-A, expressed by approximately 80% of human breast tumors. Here we evaluated the use of adoptively transferred Mammaglobin-A specific CD8 T cells in combination with low dose irradiation to induce breast tumor rejection a...
While adoptive immunotherapy using chimeric antigen receptor (CAR)-modified T cells can induce remission of some tumors, the role of other CAR-modified leukocytes is not well characterized. In this study, we characterize the function of leukocytes including natural killer (NK) cells, macrophages and CAR T cells from transgenic mice expressing a CAR under the control of the pan-hematopoietic pro...
Stereotactic body radiation therapy (SBRT) concentrates radiation to a predefined target, affecting all the cells within it. Adoptive immunotherapy is not restricted by the major histocompatibility complex (MHC) in recognizing and eliminating target cells. We investigated the effects of the combined modality of SBRT and adoptive immunotherapy on patients with advanced malignant tumors. The data...
IMMU-30. TCR Vb CLONAL EXPANSION PREDICTS RESPONSE TO ADOPTIVE IMMUNOTHERAPY AGAINST MEDULLOBLASTOMA
Cyclosporin A (CsA) is an effective modulator of multidrug resistance (MDR) in vitro and in murine tumour systems in vivo. We now report the production of immunity to L1210 leukaemia by the addition of CsA to VP-16 therapy of leukaemic BDF/1 mice. VP-16/cyclosporin A tumour immunity induction arises as a consequence of active therapy independently of immunisation with modified tumour cells. The...
