CRISPR may be used at the germline level to create organisms in which the targeted gene is changed everywhere (i.e. in all cells/tissues/organs of a multicellular organism), or it may be used in non-germline cells to create local changes that only affect certain cell populations within the organism.
Cas9 (or "CRISPR-associated protein 9") is an enzyme that uses CRISPR sequences as a guide to recognize and open up specific strands of DNA that are complementary to the CRISPR sequence. Cas9 enzymes together with CRISPR sequences form the basis of a technology known as CRISPR-Cas9 that can be used to edit genes within living organisms.
Modifying human embryos to give the CCR5 Δ32 allele protects them from the disease. An other use would be to cure genetic disorders. In the first study published regarding human germline engineering, the researchers attempted to edit the HBB gene which codes for the human β-globin protein. HBB mutations produce β-thalassaemia, which can be ...
The new exa-cel treatment under FDA consideration can use the patient’s own stem cells. Doctors would alter them with CRISPR to fix the genetic problems that cause sickle cell, and then the ...
Both treatments work by genetically modifying a patient’s own stem cells. Until now, the only known cure for sickle cell disease was a bone marrow transplant from a donor, which carries the risk ...
With the discovery of various types of immune-related disorders, there is a need for diversification in prevention and treatment. Developments in the field of gene therapy are being studied to be included in the scope of this treatment, but of course more research is needed to increase the positive results and minimize the negative effects of gene therapy applications.

Scientists at the University of California San Francisco have developed a new method to minimize the likelihood that a person's body will reject stem cells during a transplant. Using the CRISPR ...
The approach utilises the CRISPR-Cas9 gene editing system, coupled with libraries of single guide RNAs (sgRNAs), which are designed to target every gene in the genome. Over recent years, the genome-wide CRISPR screen has emerged as a powerful tool for performing large-scale loss-of-function screens, with low noise, high knockout efficiency and ...
