New protein vital for immune response is found in surprise location

...aling protein. Without MAVS, the cells were highly vulnerable to infection with two common viruses in a class called RNA viruses Other RNA viruses include hepatitis C, West Nile, SARS and the flu viruses. Cells altered to produce an overabundance of MAVS were protected from dying from viral infection. "These r...

Cellular power plants also fend off viruses

... responses by showing that cells without MAVS were vulnerable to viral infection; while those with excess MAVS were resistant to such infections. Chen speculated that the mitochondria might have evolved into immune sentinels because of their location near internal cell membranes where viral replication takes pl...

Cancer therapies during childhood can damage developing teeth

...lopment for several years. All this time teeth are vulnerable to developmental aberrations. The children examined in the current study, treated for cancer or aplastic anemia, had received stem cell transplantation at the age from 1 to 9.4 years, preceded with a high-dose anticancer chemotherapy and, in most cas...

Unusual antibiotics show promise against deadly 'superbugs'

...s might deactivate the enzyme, making the bacteria vulnerable to attack. Subsequently, the group identified a set of three novel cephalosporin antibiotics that appear to interact with the enzyme and also contain protein components that are similar to those of the bacterial cell wall. The researchers then added ...

Scientists get first glimpse at how plants, most animals repair UV-damaged DNA

...mans, mice, and all other mammals are particularly vulnerable to cancer-causing UV rays from the sun. But the rest of the animal kingdom insects, fish, birds, amphibians, marsupials, and even bacteria, viruses and yeast retained a greater ability to repair such damage. Since the 1940s, scientists have been tr...

Phytochemicals may protect cartilage, prevent pain in joints

...hat would happen, the researchers wondered, if the vulnerable chondrocyte cells in human joints were first exposed to the beneficial phase 2 enzymes? To find out, the researchers obtained compounds that boost the activity of helpful phase 2 enzymes. They added these phase 2 inducers to a dish containing the cho...
