A little while ago scientists used gene editing tool CRISPR to create an E.Coli bacteria that was resistant to every known pathogen on Earth. Then, in 2018 a Chinese scientist used the same technology immorally on two unborn twins and made them resistant to a host of deadly diseases ranging from HIV to Meningitis. He was then arrested and jailed …

These two experiments show just how powerful CRISPR is, or could be, when it comes to helping create designer humans resistant to disease – albeit an ethical, moral, and legal minefield.

Now though in a continuation of this work scientists have harnessed CRISPR gene-editing technology to block the replication of the novel coronavirus in human cells — an approach that could one day serve as a new treatment for COVID-19 and hopefully future pandemics.

However, unlike the other experiments, the study was performed in lab dishes and has not yet been tested on real animals or people, meaning a treatment based on the method could be years away.


Synthetic biology just got its own special programming language


CRISPR is a tool that enables researchers to precisely edit DNA. It’s based on a natural defense system used in bacteria that allows the microbes to target and destroy the genetic material of viruses, Live Science previously reported.

In the new study, published in the journal Nature Communications, the researchers used a CRISPR system that targets and destroys strands of RNA, rather than DNA. Specifically, their system uses an enzyme called Cas13b, which cleaves single strands of RNA, like those found in SARS-CoV-2, the virus that causes COVID-19.

The researchers designed CRISPR-Cas13b to target specific sites on the RNA of SARS-CoV-2; once the enzyme binds to the RNA, it destroys the part of the virus needed to replicate, according to a statement from the Peter MacCallum Cancer Centre in Victoria, Australia, which collaborated on the research.


New breakthrough helps drug addicts forget they were addicted


“Once the virus is recognized, the CRISPR enzyme is activated and chops up the virus,” study lead author Dr. Sharon Lewin, of the Peter Doherty Institute for Infection and Immunity at the University of Melbourne, told AFP.

The researchers also found that their method worked even when new mutations were introduced into the SARS-CoV-2 genome, including those seen in the alpha coronavirus variant, first discovered in the UK.

Effective COVID-19 vaccines are currently being distributed around the world, but there remains a “clear and urgent need” for effective treatments for the disease, the authors said. They noted that there are “serious concerns” that the virus will evolve to “escape” current vaccines.

An ideal treatment would be an antiviral drug that patients take shortly after being diagnosed with COVID-19.

“This approach — test and treat —  would only be feasible if we have a cheap, oral and non-toxic antiviral. That’s what we hope to achieve one day with this gene scissors approach,” Lewin told AFP.

Although the new study is a first step toward such a treatment, it will likely be years before this method could be turned into a treatment that’s widely available, AFP reported. The researchers now plan to test the method in animal models, and eventually conduct clinical trials in people.

Medicines that use CRISPR technology have not yet been approved to treat any diseases, but multiple studies are underway to test CRISPR-based therapies in people as a treatment for various diseases, including cancer and HIV.
