“The study is a proof of concept that CRISPR/Cas9 can be used to destroy DNA viruses and block viral infection and disease progression,” said Yinong Yang, who studies molecular plant-microbe ...

Then, if the virus is encountered again, that sequence produces a guide RNA that directs an enzyme called Cas9 to snip the viral DNA, preventing infection. These virus-specific sequences are ...

Hepatitis B virus infection remains one of the leading causes of liver disease, including cirrhosis and hepatocellular carcinoma.

1 The key component of the CRISPR system includes the Cas9 protein, which is found in bacteria where it defends against viruses. The Cas9 protein can be easily programmed to identify and bind to ...

where they help defend against viruses. The Cas9 protein is the most widely used by scientists. This protein can easily be programmed to find and bind to almost any desired target sequence ...

He studies the ways in which these viruses evade the immune system and potential therapies for these infections. Dr. Jerome and his colleagues are studying the uses of precision gene-editing tools ...

Using gene editing with CRISPR-Cas9, the team has been able to study these proteins without altering them or producing them in excess, thereby allowing ... Dec. 13, 2024 — Microorganisms produce ...
