Fox Chase Cancer Center scientists identify immune-system mutation

...or is active in all developing lymphocytes, it can redirect would-be killer cells to the CD4 helper T cell lineage. This indicates that Th-POK is a master regulator of the maturation process." Understanding the development of critical components of the immune system can contribute to medical advances in stim...

New Insights Into HIV Immunity Suggest Alternative Approach to Vaccines

... research, Haynes said. "We can focus on trying to redirect the response to HIV outer coat proteins from innate B cells to adaptive B cells. Alternatively, we can develop ways to induce that first line of polyspecific antibody defense during vaccination, if these antibodies are not harmful to those being vacc...

UCLA cancer researchers shake loose hidden biomarker

...is targeted in these cells, we identified a way to redirect this protein within the cell. We found that if we disturbed hollow tubular structures called microtubules, part of the cell's framework, we were able to relocate PSMA from its 'hidden' location on the apical membrane to an accessible area in the baso...

Neurons generated in the adult brain learn to respond to novel stimuli

...MGH-HMS CNSR. "Eventually we'd like to be able to redirect brain cell precursors or stem cells to make other types of neurons in regions of the brain that do not normally regenerate." Magavi is now a postdoctoral fellow at Massachusetts Institute of Technology. It had long been believed that neurons, the a...

The Amazon in 2050: Implementing the law could save a million square kilometers of rainforest

...hallenge of Amazon conservation is to find ways to redirect political and economic forces towards this second, more sustainable future scenario, conserving most of the forest for centuries to come. According to co-author Daniel Nepstad, "By building a policy-sensitive 'crystal ball' for the Amazon, we are abl...

Super-sized cassava plants may help fight hunger in Africa

...plant. "We wanted to find a way to help the plant redirect that excess sugar and use it to make starch," Sayre said. The researchers used a variety of cassava native to Colombia (cassava was brought to Africa from South America by the Portuguese in the 1500s.) They inserted into three cassava plants an E. c...

Beaver dams create healthy downstream ecosystems

...ams built away from natural river channels further redirect water across the valley, enhancing the depth, extent, and duration of inundation associated with smaller floods; they also elevate the water table to sustain plant and animal life during the dry summer season. "This study broadens the view of the im...

Scientists solve 30-year-old mystery of mutant mouse's kidney woes

...orders, one way to treat such diseases would be to redirect the protein to its appropriate location." Results from Chen and his colleagues are published online in the Proceedings of the National Academy of Sciences. Ultrasonic scans reveal fetal hydronephrosis, or enlargement of the kidney, in approximate...

Killing the messenger RNA -- But which one?

...ences. A single substitution in their sequence can redirect these microRNAs to target and silence entirely dif...ificity. This suggested that the change might well redirect these edited microRNAs to silence entirely different sets of genes from the unedited versions." U...

Nanotechnology shows promise as next wrinkle fighter

...can break up the compressive forces on a plane and redirect them. Once the force is reduced below the critical buckling strain, the film will not buckle. No buckles, no wrinkles. The nanoparticles in the film can be stress busters without affecting the neighboring layers. "The wrinkle-free films will autom...

Surgeons develop simpler way to cure atrial fibrillation

... incisions in the heart muscle created a "maze" to redirect errant electrical impulses. "This technology ha...gether and letting a scar form. The ablation lines redirect the abnormal electrical currents responsible for atrial fibrillation, an irregular heart rhythm in w...
