Abstract:
Immunocyte therapy for tumor has drawn a great attention in recent years due to its significant effect. Immunocytes, including T cell, NK cell and DCs, play a key role in immune responses of anti-tumors and immunotherapy of tumors. Among them, the techique of chimeric antigen receptor (CAR) modified-T cell (CAR-T) and inhibitor therapy which reverses CTLA-4 and PD-1/PD-L1 and so on immune checkpoints of tumor immune suppressive function have respectively achieved exciting results in therapies of blood tumors, melanoma and other solid tumors. How to further improve the efficacy, to increase adaptive tumor diseases and to control immune related adverse reactions of the therapy could become the focus of future research. NK cell will also take advantages of CAR technique and inhibitors of immune checkpoints to further strengthen its role in the tumor therapy. How to enhance the curative effect of DCs as the first therapeutic tumor vaccine approved by FDA based on its confirmed safe and non-toxic side effects could become a hot point. In this paper, problems that need to be solved in the field were further analyzed and prospected with combination of recent advances in the immunocyte-therapy for tumor.
