CAR T therapy can treat blood cancers by inserting new genes into a patient’s own immune cells using viruses. Early clinical trial results present an alternative that forgoes viral gene transfer: CRISPR technology. Such integration of CRISPR gene editing could improve the precision, speed and cost-effectiveness of CAR T cell production. In addition, researchers hope
A potential 1-time gene editing treatment for severe sickle cell disease (SCD) and transfusion-dependent β-thalassemia (TDT) is entering approval review by the US Food and Drug Administration (FDA), the European Medicines Agency, and the UK Medicines and Healthcare products Regulatory Agency, according to a company statement. Both diseases involve variants in the gene encoding β globin. The variants
Fifth generation polyrotaxane (PRX) carriers can effectively deliver CRISPR-Cas9 ribonucleoproteins (RNPs) The PRX carrier can cross the cell membrane, avoid endosomal action, and release Cas9 RNP for entry into the nucleusImage courtesy: Kumamoto University, The carriers, aminated polyrotaxanes, can flexibly and reversibly bind with Cas9 ribonucleoprotein and protect it from intracellular endosomal degradation CRISPR-Cas9 is
A person with a genetic condition that causes blindness has become the first to receive a CRISPR–Cas9 gene therapy administered directly into their body. The treatment is part of a landmark clinical trial to test the ability of CRISPR–Cas9 gene-editing techniques to remove mutations that cause a rare condition called Leber’s congenital amaurosis 10 (LCA10).
In the first clinical study of its kind in the US, researchers used CRISPR to modify CAR T cells to make them more potent against cancer, but the clinical benefits are unknown. mmune cells altered by CRISPR are safe to use in cancer patients, according to results of a clinical trial reported February 6 in Science.
The CRISPR (clustered regularly interspaced short palindromic repeats)-based genome editing technology is an emerging RNA-guided nuclease system initially identified from the microbial adaptive immune systems. In recent years, the CRISPR system has been reprogrammed to target specific regions of the eukaryotic genome and has become a powerful tool for genetic engineering. Researchers have explored many
Early results suggest that prime editors are cleaner than CRISPR–Cas9 and more versatile than base editors, but many questions remain. A paper recently published in Nature from David Liu and co-workers discloses a ‘prime’ gene-editing system many years in the making. In principle, the system, comprising a catalytically impaired Cas9 enzyme and an engineered reverse transcriptase, may
The first ever analysis of all the tweets discussing Crispr gene-editing has revealed how the public feels about the technology. The findings suggest that over a six years public approval of gene-editing has cooled and that most people chatting about the technology are worried. Twitter offers researchers a vast amount of semi-structured data and provides direct access
Gene editing to correct genetic faults and removing the risk of hereditary diseases may soon become reality. Researchers have come up with a new gene editing technology that could help patients with sickle cell anaemia and up 89 percent of other genetic defects. This new technique is called the “prime editing” and is being developed
A California “human biohacking” bill calls for warnings on do-it-yourself genetic-engineering kits. Source Technology Review It’s going to be illegal in California to sell “gene-therapy kits” unless they carry a warning that says not to use them on yourself. Just one wrinkle: we’re not sure any such kit exists. Not yet, anyway. The consumer protection
