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.

Engineering viruses to kill deadly pathogens

Science Daily: Pharmacology News

Researchers are exploring phages, viruses that infect bacteria, as a possible solution. In the new study, researchers successfully modified DNA from four types of phages to kill a deadly pathogen. Antimicrobial resistance is an urgent and growing global crisis.

Gene editing extends lifespan in mouse model of prion disease

Broad Institute

The treatment, which uses base editing to make a single-letter change in DNA, reduced levels of the disease-causing prion protein in the brain by as much as 60 percent. But the researchers needed to deliver the base editors to the brain. They then administered the AAVs to mice infected with the human prion protein.

Researchers engineer in vivo delivery system for prime editing, partially restoring vision in mice

Broad Institute

Williams January 8, 2024 Credit: Susanna Hamilton, Broad Communications Researchers have developed virus-like particles that can deliver gene-editing cargo to cells, including those in the mouse brain. Prime editing, described in 2019 by Liu’s group, can make longer and more diverse types of DNA changes than other types of editing.

New research shows HIV can lie dormant in the brain

SCIENMAG: Medicine & Health

As a part of its life cycle, the human immunodeficiency virus-1 (HIV) inserts a copy of its DNA into human immune cells. Some of these newly infected immune cells can then transition into a dormant, latent state for a long period of time, which is referred to as HIV latency. Credit: UNC Division of Infectious […]
