New method allows scientists to study how HIV persists
Scientists have developed a new strategy to study the cells that host hidden reserves of dormant HIV, a step that may lead to new treatments that go beyond controlling the infection and instead aim to eradicate the virus entirely.
From infection-dodging stem cells, new tactics for research on viral disease
Among other superpowers, stem cells have a knack for fending off viruses like dengue and zika. Scientists have gained new insight into these curious defense strategies—knowledge they say could fuel the development of drugs against a range of diseases.
Scientists map the portal to the cell’s nucleus
The gateway to cellular headquarters has 552 components. A new map that shows how all these pieces fit together could help scientists study numerous diseases.
Scientists caution that a rare childhood liver cancer can spread to the brain
A new report details three cases of secondary brain tumors in people with fibrolamellar hepatocellular carcinoma. The researchers say imaging tests could improve treatment for patients whose cancer spreads to the brain from the liver.
Molecule discovered in dirt could help against multi-resistant bacteria
In mining soil for natural drugs, scientists have discovered a brand-new antibiotic potent against many bacteria. They hope it could be used to treat infections that cannot be stopped with existing drugs.
In brief: Tweaking RNA protects cells from harmful inflammation
New research has helped explain what goes wrong in Aicardi-Goutières syndrome, a rare brain disorder. Patients with the disease have genetic abnormalities that may put their cells at risk of accidentally triggering an antiviral response.
In brief: Mutation explains why some people are more vulnerable to viral brain infection
Scientists identified mutations in a single gene that impair immunity to viruses in a region of the brain called the brain stem.
New tool for tracking “kiss-and-run” communication between cells could advance research in multiple fields
Virtually all aspects of life and disease depend of brief exchanges between cells. A new technique to study cell-to-cell contacts lets interacting cells “smear” one another with the biological equivalent of lipstick.
New immunotherapy approach boosts body’s ability to destroy cancer cells
A new treatment may help cancer patients who don't respond to traditional immunotherapy. Findings from the first-ever clinical trial reveal that it is effective in activating immune cells that kill cancer cells.
In brief: Variation between strains may account for differences in people’s vulnerability to infection
New research shows that subtle differences between bacterial strains may cause dramatic differences in outcome between people infected with the same microbe.
