Scientists erased memories from rats with CRISPR genome editing

Genome Editing with CRISPR-Cas9

Neuroscientists have developed technology to remove pathological memories for the treatment of PTSD, drug addiction and certain chronic diseases.

Negative emotions, such as fear, are necessary for our survival, but when a person cannot cope with them and forget, then this can cause various disturbances. Treating pathological memories can relieve conditions such as PTSD, chronic pain and stress, and drug addiction.

Researchers at Peking University have developed a new system for modifying the genome in various types of cells, including neurons in the brain. They reported the successful use of this CRISPR-cas9-based technology to kill genes related to fear memory in laboratory rats..

Physicians around the world are currently experimenting with genome editing to treat chronic and congenital diseases. However, applying similar methods to people related to a number of ethical issues.
