Scientists erase rat memories with CRISPR genome editing

Neuroscientists have developed a technology that allows you to remove pathological memories for the treatment of PTSD, drug addiction and some chronic diseases.

Negative emotions, such as fear, are necessary for us to survive, but when a person cannot cope with them and forget, then this can cause various disturbances. Treatment of pathological memories allows you to get rid of conditions such as post-traumatic stress disorder, chronic pain and stress, as well as drug addiction.

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

Doctors around the world are currently experimenting with genome editing for the treatment of chronic and congenital diseases. However, the application of such methods to people is associated with a number of ethical issues.
