CRISPR-Cas9 genome editing for cancer immunotherapy: opportunities and challenges.
BRIEFINGS IN FUNCTIONAL GENOMICS(2020)
Abstract
Cancer immunotherapy, consisting of antibodies, adoptive T-cell transfer, vaccines and cytokines, is a novel strategy for fighting cancer by artificially stimulating the immune system. It has developed rapidly in recent years, and its efficacy in hematological malignancies and solid tumors has been remarkable. It is regarded as one of the most promising methods for cancer therapy. The current trend in immunotherapy research seeks to improve its efficacy and to ensure the safety of cancer immunotherapy through the use of gene editing technologies. As it is an efficient and simple technology, the CRISPR-Cas9 system is highly anticipated to dramatically strengthen cancer immunotherapy. Intensive research on the CRISPR-Cas9 system has provided increasing confidence to clinicians that this system can be put into clinical use in the near future. This paper reviews the application and challenges of CRISPR-Cas9 in this field, based on various strategies including adaptive cell therapy and antibody therapy, and also highlights the function of CRISPR/Cas9 in the screening of new cancer targets.
