By Michael Irving January 04, 2023 A new type of treatment turns cancer cells into double agents that kill existing tumors Depositphotos Scientists at Brigham and Women’s Hospital (BWH) have found a way to fight cancer with cancer. The team genetically engineered cancer cells to release anti-cancer drugs at the site of established tumors, as...
By Rich Haridy January 04, 2023 Researchers genetically modified bacteria to secrete a peptide found to reduced inflammation associated with several autoimmune diseases Depositphotos Instead of injections or pills, why not engineer bacteria to secrete therapeutic molecules from within our gut? A new study is demonstrating this futuristic idea, showing how a genetically modified probiotic...

Clonidine is commonly used as a high...
by Sanford Burnham Prebys Medical Discovery Institute Duc Dong, Ph.D. Credit: Sanford Burnham Prebys Research led by Associate Professor Duc Dong, Ph.D., has shown for the first time that the effects of Alagille syndrome, an incurable genetic disorder that affects the liver, could be reversed with a single drug. The study, published in the Proceedings of the...
by Baylor College of Medicine Credit: Unsplash/CC0 Public Domain Researchers at Baylor College of Medicine have found more evidence that dry fasting (fasting without food or liquid intake) from dawn to dusk can play an important role in overall health. In a new study published in Metabolism Open, researchers found that fasting from dawn to dusk for four...
by Wayne Lewis, University of California, Los Angeles The SymphNode device (left), contains nanoparticles (red dots) that release a drug that blocks the activity of regulatory T cells (green), which suppress the body’s response to solid tumors. At the same time, the SymphNode’s microparticles (black dots) attract and beef up cancer-fighting T cells. Credit: Negin...

by Mary-Ann Muffoletto, Utah State University Credit: Utah State University Utah State University biochemists Thomson Hallmark and Ryan Jackson, along with collaborators, published two seminal papers this week. Their findings describe the structure and function of a newly discovered CRISPR immune system that—unlike better-known CRISPR systems that deactivate foreign genes to protect cells—shuts down infected cells...

Rare cell types can have an undue influence on human health. Previous research has suggested that a subset of astrocytes—star-shaped cells in the brain and spinal...
