How an AIDS-Related Cancer Unleashes Inflammation

...otein called MK2, which is known to play a role in boosting cytokine production. In further experiments, they discovered that the binding of kaposin B activated MK2, leading to higher levels of cytokines in the cell. Activated MK2 does this by prolonging the stability of cytokine messenger RNA ?the genetic b...

Stopping smallpox in its tracks: A new anti-viral approach

...effective in lowering morbidity and mortality, and boosting T cell immunity, in infected mice. In an accompanying commentary, Anthony Fauci and Mark Challberg from the National Institutes of Health point out that this approach "may serve to turn the tables on the virus by interfering with the very pathways t...

Test for early detection of prostate cancer shows promise

... benign prostate conditions are not detected, thus boosting doctors?confidence that a positive EPCA test is really a sign of prostate cancer, added Getzenberg. “Once this test is refined and approved for general use, it will have an impact on the detection and treatment of prostate cancer,?said Getzenberg. ...

Remote control flies? Fly behavior controlled by laser light

...led dopaminergic neurons with the remote controls, boosting the flies' activity levels and changing their flight paths. Misenböck says the triggered behaviors can last seconds or continue for minutes, depending on whether the neural circuit activated by the remote control has feedback loops that keep the cir...

Brain Scan Study of Smokers Reveals Signature of Craving

...en cigarette cues and brain activity as a means of boosting quitting success rates. For example, methods in which people switch to nicotine-free cigarettes prior to smoking cessation may help extinguish the connection between smoking and the rewarding affects of nicotine, thereby easing the brain's sensitivit...

Researchers discover stem cell 'guide' that may be key for targeting neural stem cell treatments

...is protein is an attractive drug target for either boosting neuron-forming processes or stem cell-based therapies for diseases like Alzheimer's and Parkinson's, or for stroke and other brain injuries." While all neurons are originally born and differentiated from their stem cell progenitors during developmen...

New protein vital for immune response is found in surprise location

... expression or activity may be a viable option for boosting immune responses against viral diseases." The fact that MAVS is located within the membrane of the mitochondrion makes sense for a couple of reasons, Dr. Chen said. First, proteins housed within the mitochondria have been shown by researchers, suc...

Study: Predatory dinosaurs had bird-like pulmonary system

...eases the gas exchange potential within the lungs, boosting metabolism and creating warm-bloodedness. The researchers are quick to point out, however, that the new study doesn't clearly peg predatory dinosaurs as habitually warm-blooded animals. The creatures probably had a more complex strategy, falling some...

Breast tumors in mice eradicated using cancer vaccine

... more properly described as immunotherapy, work by boosting an immune response against tumor-associated antigens. Using Listeria, the researchers, led by Yvonne Paterson, PhD, Professor of Microbiology, delivered the tumor-associated antigen HER-2/Neu to immune cells. HER-2/Neu is overexpressed in 20 to 40 ...

GM crop that holds on to its seeds offers higher yields

Researchers have found a way of boosting the yield of a major crop by stopping its seedpods from bursting open. Indian mustard (Brassica juncea) is the most important oilseed crop in India after groundnut. It is grown largely to produce cooking oil from the seeds. However, because the seed...

Rutgers researchers scientifically link dancing ability to mate quality

...ess and the same size ?all to keep evaluators from boosting or dropping dancers' scores based on considerations other than dance moves. The researchers also evaluated each dancer for body symmetry, an accepted indicator in most animal species ?including humans ?of how well an organism develops despite proble...

There's something fishy about human brain evolution

...ng the larder, shorelines provided essential brain boosting nutrients and minerals that launched Homo sapiens brains past their primate peers, says Dr. Cunnane, the Canada Research Chair in Brain Metabolism and Aging. Brain development and function requires ample supplies of a particular polyunsaturated fatt...

Potential vaccine developed for deadly leishmaniasis disease

... viruses. The virosome also acts as an "adjuvant," boosting the immune response of the candidate vaccine. The antigen is a synthetic carbohydrate similar to substances on the surface of the leishmaniasis bacteria. With laboratory studies showing that the candidate vaccine produces a strong protective action ...

Faster immune system testing set to improve poultry quality

...useful. Combining this test with new immune-system boosting drugs would improve poultry welfare, and result in cheaper and better quality poultry products for European consumers. Poultry is the fastest growing livestock industry worldwide, benefiting from production and price advantages as well as being view...

Weizmann Institute suggests that immune cells help to maintain cognition and brain cell renewal

...s in memory skills. Therefore, by manipulating and boosting the immune system, it might be possible to prevent or at least slow down age-related loss of memory and learning abilities. ...

Protein finding could lead to treatment for inflammatory diseases

...MCV-infected skin cells, to prevent cytokines from boosting the immune system. MC160 is probably helping the virus persist." Upon further examination, Shisler and Nichols discovered that MC160 shuts down the NF-kB-triggered inflammatory response by degrading a subunit of the immune system's I Kappa Kinase (I...

Nobelist discovers antidepressant protein in mouse brain

...compensate for reduction in serotonin signaling by boosting levels and binding of serotonin to receptors. Previous studies have suggested that serotonin receptors are essential in regulating moods and in mediating the effects of SSRIs, but given the complexity of the serotonin system, exactly how these recept...

Weighting cancer drugs to make them hit tumors harder

Scientists have devised a blueprint for boosting anti-cancer drugs' effectiveness and lowering their toxicity by attaching the equivalent of a lead sinker onto the drugs. This extra weight makes the drugs penetrate and accumulate inside tumors more effectively. Chemotherapy drugs often fall short ...
