Edible bivalves as a source of human pathogens: signals between vibrios and the bivalve host.

...explains: "In bivalves, immunity is carried out by circulating haemocytes and soluble haemolymph factors that act in a co-ordinate way to kill microorganisms. Our research examines available data on Vibrio interactions with both cellular and soluble components of the bivalve immune system in the light of the cap...

Genetic therapy reverses nervous system damage in animal model of inherited human disease

...would block the virus carrying the gene if it were circulating in the bloodstream, the researchers injected the virus directly into the brain. "The brain of the cat is much closer in size to the human infant brain compared to mice. Thus we think that it may be possible to achieve similar results in humans with ...

Mouse with designer liver has enhanced glucose tolerance, insulin response

...rides in the liver with a commensurate decrease of circulating triglycerides in the bloodstream. Insulin response to glucose load was diminished in LGKO mice, thus glucose tolerance in the liver was significantly improved in the absence of Gab1 protein. The Feng team conducted biochemical analyses on the LGKO m...

Ebola virus: from wildlife to dogs

...emics means that the Ebola virus has probably been circulating for a long time in Central African forests. The detection of such antibodies in other primate species (including 5 drills, 1 baboon and 1 mandrill) suggests that circulation of the virus involved many contamination events between distinct animal spec...

NCI Researchers Confirm the Effectiveness of Immunotherapy Approach to Treating Melanoma

...rugs were used to reduce the number of lymphocytes circulating in the blood, therefore reducing competition for the newly activated tumor-fighting lymphocytes being reintroduced in to the blood stream. After the seven days of chemotherapy, the patients received their own lymphocytes that had been renewed with i...

Enlisting genomics to understand flu evolution

Multiple strains of the flu virus, circulating in a population at the same time, can reshuffle their genes and create a new virus, one capable of infecting many more people, according to a new study in the open-access journal PLoS Biology. This finding may help scientists make better predictions ...

Purdue scientists may have found key to halting spinal cord damage

...ls, and it's certainly wise to have plenty of them circulating in your bloodstream," he said. "The trouble is that when free radicals start attacking tissue, it happens in a tiny fraction of a second, after which they are gone. But the acrolein that these attacks release survives in our bodies much longer, for s...

Identification of specific genes predicts which patients will respond to Hepatitis C treatment

In order to define which genes discriminate between those patients who respond to therapy to those who do not, microarray technology, based in a Banting and Best Department of Medical Research laboratory at...

Scientists find that protein controls aging by controlling insulin

... the researchers discovered, it acts as a hormone, circulating through the blood and binding to cells. Therapies based on this hormone could prove to be a way to extend life or slow its effects, said Dr. Makoto Kuro-o, assistant professor of pathology and senior author of the study published in today's online i...

The mechanisms driving this increase as well as its potential clinical significance, however, have remained unclear, note the scientists. Using two relatively new techniques for labeling cells, the team demonstrated that IL-2 therapy can...

Mitochondria are structures within cells that provide energy for cells to move, divide, contract and secrete products vital for the health of organisms.
