The ability to alter gene expression directly in T lymphocytes has provided a powerful tool for understanding T cell biology, signaling, and function. Manipulation of T cell clones and primary T cells has been accomplished primarily through overexpression or gene-silencing studies using cDNAs or shRNAs, respectively, which are often delivered by retroviral or lentiviral transduction or direct transfection methods. The recent development of CRISPR/Cas9-based mutagenesis has revolutionized genomic editing, allowing unprecedented genetic manipulation of many cell types with greater precision and ease. This article outlines a protocol for CRISPR/Cas9-mediated mutagenesis in primary T lymphocytes from Cas9 transgenic mice using retroviral delivery of guide RNAs. © 2018 by John Wiley & Sons, Inc.

CRISPR-Cas9 technology is routinely applied for targeted mutagenesis in model organisms and cell lines. Recent studies indicate that the prokaryotic CRISPR-Cas9 system is affected by eukaryotic chroma...
Electroporation of zygotes represents a rapid alternative to the elaborate pronuclear injection procedure for CRISPR/Cas9-mediated genome editing in mice. However, current protocols for electroporatio...
The quality and efficiency of any PCR-based mutagenesis technique may not be optimal due to, inter alia, amino acid bias, which means that the development of efficient PCR-free methods is desirable. H...
As a powerful tool for fast and precise genome editing, the CRISPR/Cas9 system has been applied in filamentous fungi to improve the efficiency of genome alteration. However, the method of delivering g...
Delivery of CRISPR (clustered regularly interspaced short palindromic repeats)/CRISPR-associated protein-9 (Cas9) represents a major hurdle for successful clinical translation of genome editing tools....

Patients eligible for this study have a type of blood cancer called T-cell leukemia or lymphoma (lymph gland cancer). The body has different ways of fighting infection and disease. This s...
This is a single-arm, open-label, multi-site, single-dose Phase 1/2 study in up to 12 subjects 18 to 35 years of age with transfusion-dependent β-thalassemia (TDT), non-β0/β0. The study...
Protein components of the CRISPR-CAS SYSTEMS for anti-viral defense in ARCHAEA and BACTERIA. These are proteins that carry out a variety of functions during the creation and expansion of the CRISPR ARRAYS, the capture of new CRISPR SPACERS, biogenesis of SMALL INTERFERING RNA (CRISPR or crRNAs), and the targeting and silencing of invading viruses and plasmids. They include DNA HELICASES; RNA-BINDING PROTEINS; ENDONUCLEASES; and RNA and DNA POLYMERASES.
Adaptive antiviral defense mechanisms, in archaea and bacteria, based on DNA repeat arrays called CLUSTERED REGULARLY INTERSPACED SHORT PALINDROMIC REPEATS (CRISPR elements) that function in conjunction with CRISPR-ASSOCIATED PROTEINS (Cas proteins). Several types have been distinguished, including Type I, Type II, and Type III, based on signature motifs of CRISPR-ASSOCIATED PROTEINS.
An anti-CTLA-4 ANTIGEN monoclonal antibody initially indicated for the treatment of certain types of metastatic MELANOMA. Its mode of actions may include blocking of CTLA-4 mediated inhibition of CYTOTOXIC T LYMPHOCYTES, allowing for more efficient destruction of target tumor cells.
Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.
Genetically engineered MUTAGENESIS at a specific site in the DNA molecule that introduces a base substitution, or an insertion or deletion.
Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
The process of gene expression is used by eukaryotes, prokaryotes, and viruses to generate the macromolecular machinery for life. Steps in the gene expression process may be modulated, including the transcription, RNA splicing, translation, and post-tran...
