The Rare Mutation That Makes People Immune to Viruses

The Rare Mutation That Makes People Immune to Viruses

A rare genetic condition that once looked like a weakness has revealed a hidden strength: immunity against nearly all viruses. Credit: Shutterstock Some people carry a rare mutation that makes them resistant to viruses. Now scientists have copied that effect with an experimental mRNA therapy that stopped both flu and COVID in animal trials — raising hopes for a universal …

Trojan horse bacteria sneak cancer-killing viruses into tumors

Trojan horse bacteria sneak cancer-killing viruses into tumors

Researchers at Columbia Engineering have built a cancer therapy that makes bacteria and viruses work as a team. In a study published recently in Nature Biomedical Engineering, the Synthetic Biological Systems Lab shows how their system hides a virus inside a tumor-seeking bacterium, smuggles it past the immune system, and unleashes it inside cancerous tumors. The new platform combines the bacteria’s …

Bacteria and Viruses Join Forces in New Cancer-Killing Therapy

Bacteria and Viruses Join Forces in New Cancer-Killing Therapy

Summary: Researchers have developed CAPPSID, a novel cancer therapy that teams bacteria and viruses to infiltrate and destroy tumors. The system hides an oncolytic virus inside Salmonella typhimurium, which naturally migrates into tumors, shielding the virus from immune detection. Once inside, the bacteria release the virus directly into cancer cells, where it replicates and spreads throughout the tumor. Built-in safeguards …

Two common viruses may ‘reignite’ cancer cells in people decades after remission

Two common viruses may ‘reignite’ cancer cells in people decades after remission

Cancer survivors could see the disease return with a vengeance if they contract a common virus, new research suggests.  A study, led by scientists from the University of Colorado Anschutz Medical Campus, looked at how Covid-19 and influenza could awaken dormant breast cancer cells that have spread to the lungs.  In remission, dormant cancer cells can exist undetected in the body and …

Ancient viruses embedded in our DNA help switch genes on and off, study finds

Ancient viruses embedded in our DNA help switch genes on and off, study finds

DNA that humans acquired from ancient viruses plays a key role in switching parts of our genetic code on and off, a new study has found. Nearly half of the human genome consists of segments called transposable elements (TEs), also known as “jumping genes” because they can hop around the genome. Some of these TEs are remnants of ancient viruses …

Common Viruses May Wake Dormant Breast Cancer Cells, Study Finds : ScienceAlert

Common Viruses May Wake Dormant Breast Cancer Cells, Study Finds : ScienceAlert

Breast cancer patients who have been in remission for years or even decades may still need to be cautious about respiratory infections. Some common viruses may re-awaken a very small number of dormant breast cancer cells within our lungs, according to emerging research. “Dormant cancer cells are like the embers left in an abandoned campfire, and respiratory viruses are like …

West Nile, Jamestown Canyon viruses found in Westmoreland mosquitoes; Lyme risk high

West Nile, Jamestown Canyon viruses found in Westmoreland mosquitoes; Lyme risk high

Westmoreland Conservation District is urging residents to take precautions against tick and mosquito bites as samples of the pests collected in the county have tested positive for Lyme disease, West Nile virus and a less familiar new threat — Jamestown Canyon virus. Chrissy Edwards-McCune, West Nile Virus coordinator for the conservation district, reported Tuesday that West Nile virus has been …

Deadliest Creature Alive Spreading These Viruses In New York

Deadliest Creature Alive Spreading These Viruses In New York

It’s smaller than your fingernail and kills more humans than any other animal on Earth. Now it’s spreading fast across New York,  and it’s already infected people. The New York State Department of Health wants New Yorkers to remember the dangers of mosquito bites and protect against diseases like West Nile Virus and Eastern Equine Encephalitis (EEE). New York State …
