Nanorobot hand made of DNA grabs viruses for diagnostics and blocks cell entry

Science Daily: Pharmacology News

A tiny, four-fingered 'hand' folded from a single piece of DNA can pick up the virus that causes COVID-19 for highly sensitive rapid detection and can even block viral particles from entering cells to infect them, researchers report.

Scientists just discovered a secret code hidden in your DNA

Science Daily: Pharmacology News

What scientists once dismissed as junk DNA may actually be some of the most powerful code in our genome. A new international study reveals that ancient viral DNA buried in our genes plays an active role in controlling how other genes are turned on or off, especially during early human development.

Cold sore virus hijacks human genome in 3D--and scientists found its weak spot

Science Daily: Pharmacology News

Cold sore-causing HSV-1 doesn't just hijack cells it reconfigures the entire architecture of our DNA to aid its invasion. Stunningly, blocking this single enzyme shuts the virus down completely.

Scientists create next generation of tools in battle against brain disease

Broad Institute

The team has successfully created over 1000 of them, and each consist of: a harmless adeno-associated virus (or AAV) that acts like a shuttle capable of transporting specially designed DNA into the cell; a segment of DNA (an enhancer) that acts like an activation switch to mark or trigger a change in how the cell functions.

Prime editing treats childhood brain disease in mice

Broad Institute

The ability to precisely edit DNA directly in the brain has important implications for neurological diseases, said Cathleen Lutz, vice president of the Rare Disease Translational Center at The Jackson Laboratory and co-senior author of the study. Liu is also a Howard Hughes Medical Institute investigator and a professor at Harvard University.

A Visual Guide to Genome Editors

Codon

Certain CRISPR components can add short DNA sequences from the genomes of defeated viruses into the bacterium’s own genome, creating a type of protective “memory.” If the same virus invades the cell a second time, the gRNA’s spacer sequence will bind to the matching viral DNA sequence, then be cut by the Cas protein.
