Blocking immune cell action increases Alzheimer's-associated protein deposits

...o clarify the role of microglia in Alzheimer's and identify factors involved in the immune cells' accumulation at amyloid plaques. The research team focused on a molecule called CCR2, a receptor on the surface of microglia and other immune cells that is known to help direct them from the bloodstream to si...

New nanotechnology able to examine single molecules, aiding in determining gene expression

...eported in Nanotechnology were able to isolate and identify individual transcript molecules—a sensitivity not achieved with earlier methods. "Gene expression profiling is used widely in basic biological research and drug discovery," said Jason Reed of UCLA's Department of Chemistry and Biochemistry and the...

Anti-dandruff compound may help fight epilepsy

...ctivity of the new channels, the researchers could identify molecules that accelerated the recovery. One chemical that proved quite effective in improving channel recovery was zinc pyrithione (ZnPy), the active ingredient in many dandruff shampoos. Li explains that ZnPy has a shape that allows it to fit i...

Minuscule molecules pack a powerful punch

...he immune system, the team used genomic studies to identify protein genes whose activity was controlled by miR-155 in T-cells. Activity of more than 150 genes, with a large range of biological functions, was reduced by miR-155, demonstrating its role in the immune system. The team showed that a particularly i...

Drug treatment improves learning in mice with Down syndrome symptoms, Stanford/Packard study shows

...at affected mice were significantly better able to identify novel objects and navigate a maze ­ tasks that simulate difficulties faced by children and adults with Down syndrome ­ after being fed 17 daily doses of milk containing a compound called pentylenetetrazole, or PTZ. Treated mice performed as well as t...

Syphilis rate on rise in US gay, bisexual men

...ed by 62 percent. While syphilis statistics do not identify the gender of the sex partners of infected people, the study authors infer that a large number of those infected ?62 percent in 2003 ?are gay or bisexual, in part, because so few women become infected. The study does not look past 2003, but stati...

New test helps identify hepatitis C patients at high risk of developing cirrhosis

...s that helped determine that the genetic test can identify patients who are at high risk of developing cirrhosis from chronic hepatitis C infection. That means high-risk patients could be directed toward a long course of expensive, debilitating drug therapy, while low-risk patients might be better off de...

Scientists identify a candidate gene for osteoporosis

...We will also be able to develop genetic screens to identify individuals who are at risk for osteoporosis." According to the National Osteoporosis Foundation, osteoporosis affects 55% of Americans over the age of 50. Low bone mineral density (BMD)—the primary indicator of osteoporosis—is influenced by both...

Chromosomal microarray analysis proves accurate

They also envision a drug or other type of treatment to protect infants who have abnormalities in their brainstem serotonin system. The brainstem serotonin system is thought to help coordinate breathing, blood pressure,...
