TB bacteria's trash-eating inspires search for new drugs
(Phys.org) —When hijacking a garbage truck, one might as well make use of the trash. That logic drives how tuberculosis-causing bacteria feed, say Cornell scientists.

The body's immune system exists to identify and destroy foreign objects, whether they are bacteria, viruses, flecks of dirt or splinters. Unfortunately, nanoparticles designed to deliver drugs, and implanted ...
(Phys.org)—Carbon nanotubes resemble asbestos fibers in their form. Unfortunately, long, pure nanotubes also seem to have asbestos-like pathogenicity. In the journal Angewandte Chemie, a European resear ...
The Wip1 protein is important for survival, but mutations that inactivate it carry some surprising features. "A lack of Wip1 results in an excessive immune reaction to infectious organisms, in some cases ...
(Phys.org)—Scientists at The Scripps Research Institute (TSRI) have discovered the first selective inhibitors of an important set of enzymes. The new inhibitors, and chemical probes based on them, now can be used to study ...
(Phys.org)—Macrophages are heavy hitters of the immune system. Their name literally means "to eat large objects." They are critical members of the body's defense team, such as in the lungs where they ingest ...
One of the challenges in treating cancer, whether using nanotechnology or not, is that tumors can often be inaccessible to the therapies designed to kill them. Mostafa El-Sayed, of the Georgia Institute of Technology, and ...
A new computational model developed by a team of Virginia Tech researchers and published in PLoS Computational Biology provides a framework to better understand responses of macrophage cells of the human ...
Researchers at Cambridge University have shed new light on a common food poisoning bug. Using real-time video microscopy, coupled with mathematical modelling, they have changed our assumptions about Salmonella and how it ...
Scientists have found why a certain type of bacteria, harmless in healthy people, is so deadly to patients with cystic fibrosis.
The theory that pigeons' famous skill at navigation is down to iron-rich nerve cells in their beaks has been disproved by a new study published in Nature.
Sometimes our immune defence attacks our own cells. When this happens in the brain we see neurodegenerative diseases such as dementia, Alzheimer's and Parkinson's disease. But if the the immune defence is inhibited, the results ...
Researchers from the University of Iowa Roy J. and Lucille A. Carver College of Medicine have found that inhaled carbon black nanoparticles create a double source of inflammation in the lungs.
Researchers at the University of California, San Diego School of Medicine say a "stress response" mechanism used by normal cells to cope with harsh or demanding conditions is exploited by cancer cells, which ...
Viruses can penetrate every part of the body, making them potentially good tools for gene therapy or drug delivery. But with our immune system primed to seek and destroy these foreign invaders, delivering therapies with viruses ...
