How CRISPR/Cas9 Gene Editing Is Revolutionizing T Cell Research.

Clustered regularly interspaced short palindromic repeats (CRISPR)/Cas9 allows for precise gene targeting in mammalian cells, including T cells, allowing scientists to disrupt or edit specific genes of interest. This has enabled immunologists to investigate T cell functions as well as opened the path for novel therapeutics involving gene editing of T cells ex vivo before transferring these back to patients to increase T cell efficacy. This review outlines how CRISPR/Cas9 has transformed T cell research allowing immunologists to rapidly probe the roles of genes in T cells thus paving the way for novel therapeutics. Furthermore, this review describes how these tools reduce the requirement for genetic mouse models, while increasing the translational potential of T cell research.
