CRISPR gene editing is a revolutionary technology that allows for precise, targeted modifications to the DNA of living organisms. Developed from a natural defense mechanism found in bacteria, CRISPR-Cas9 is the most commonly used system, that allows "cutting" of DNA at specific locations and either delete, modify, or insert genetic material.
CRISPR has also been used to cure malaria in mosquitos, which could eliminate the vector and the disease in humans. [171] CRISPR may also have applications in tissue engineering and regenerative medicine, such as by creating human blood vessels that lack expression of MHC class II proteins, which often cause transplant rejection.

In April 2015, a research team published an unsuccessful experiment in which they used CRISPR to edit a gene that is associated with blood disease in non-living human embryos. researchers using CRISPR/Cas9 have run into issues when it comes to mammals due to their complex diploid cells. Studies in microorganisms have examined loss of function ...
A technology named clustered regularly interspaced short palindromic repeat (shortened to CRISPR-Cas9) was discovered in 2012. The new technology allows anyone with molecular biology training to alter the genes of any species with precision, by inducing DNA damage at a specific point and then altering DNA repair mechanisms to insert new genes ...
CRISPR/Cas9 technology is not actively used today, however there are ongoing clinical trials of its use in treating various disorders, including sickle cell disease, human papillomavirus (HPV)-related cervical cancer, COVID-19 respiratory infection, renal cell carcinoma, and multiple myeloma. [56]
Mammoth's CRISPR-based gene editing platform and Regeneron's delivery technologies will be used to create disease-modifying medicines that can be delivered to tissues beyond the liver. CRISPR ...
One example is the so-called vision restoration gene therapy, that aims to restore vision in patients with end-stage retinal diseases. [70] [71] In end-stage retinal diseases, the photoreceptors, as the primary light sensitive cells of the retina are irreversibly lost. By the means of prosthetic gene therapy light sensitive proteins are ...
The most common type in humans is called Creutzfeldt-Jakob disease. Prion diseases occur after a normal prion protein, which is found on the surface of cells, becomes abnormal.
