Melanoma vaccine strategy shows promise in laboratory experiments

...nts, about 50 percent, have killer T cells able to recognize the BRAFV600E peptide. Combining the prevalence of the peptide among melanoma patients ?about 70 percent ?with the number of patients whose immune cells are able to respond to the peptide suggests that a vaccine based on BRAFV600E could treat approxi...

Guiding principles for facial transplantation unveiled

...ansplant patients). "As plastic surgeons we fully recognize the revolutionary prospects of facial transplantation," said William C. Pederson, MD and president of ASRM. "We just need to make sure that we approach this challenge having reflected on all the possibilities for both the patient and the surgical tea...

Simple idea to dramatically improve dengue vaccinations

...ess, it identifies three to five T-cells that best recognize and attack the components of the sickened cells. Once the cells are selected, they are produced by the millions and sent out to clear the infection. After the infection is gone, thousands of these pre-programmed T-cells remain in the body, lying in w...

Clawed frog helps Fanconi anemia research make leaps

...ss there's replication, the Fanconi proteins don't recognize the damage." "We wanted to develop an approach that would allow us to determine how the Fanconi proteins assemble on replicating DNA and what proteins control the important steps. These extracts give us the tool we need for those experiments," she s...

Researchers unlock how cells determine their functions

...ver, the mechanisms by which epigenetic activators recognize and bind these target genes was not yet known" Sauer pointed out "What we were able to show is that the epigenetic activator Ash1is recruited to a target gene through cell-type specific non-coding RNA" he said. The paper examined how the activato...

Birth defects: 8 million annually worldwide

...a "huge problem but there are countries that don't recognize or monitor it," Prof. Christianson says. "Around the world, fetal alcohol syndrome is one of the more common fetal environmental problems." Professor Modell has worked for many years to develop the database, using all information available and extr...

Web model of influenza-host lifecycles will aid scientists in creating anti-viral drugs

... at the same time blocking the host reactions that recognize and respond to infection. Each year, for example, winter is marked by the outbreak of flu caused by new viruses that the human immune system doesn't recognize. The new Reactome influenza database outlines a typical virus life cycle, which will be up...

Infant transplant patients resist infections that kill adult AIDS patients

... with receptors on their surfaces enabling them to recognize many different microorganisms. The diversity of lymphocytes is enormous. Each person has an estimated 1 billion different T cells capable of fighting various infections and another 1 billion of a different kind of immune system cell, the B cell, whic...

New U. of Colorado at Boulder flu chip may help combat future epidemics, pandemics

...aser scanner. The Flu Chip also should be able to recognize mutations that might occur in avian flu H5N1, which has been spreading rapidly from bird to bird in Asia, Russia and parts of Europe, said Kuchta. While the avian virus does not now spread effectively from person to person, world health officials ar...

Some good news for the world's poor

...igler emphasized. "But it's very important that we recognize what strategies really do have an impact so we can focus our resources on such techniques, and rice research is clearly one of these." Dr. Fan's research follows earlier work by IRRI that showed that, in the four decades from 1961 to 2000, while the...

Plant defenses prompt bacterial countermeasure in the form of 'island' DNA excision

...can be successful is that the plant has evolved to recognize the presence of only certain bacterial proteins as warnings of an infection. This means that the bacteria can, in principle, evade detection if it can shut down production of the offending protein or proteins. In their study, the authors identify wit...

Clinical trial to test stem cell approach for children with brain injury

... "It could be the difference between being able to recognize your loved ones and not being able to, or between doing things for yourself or having to rely on others. That would be a huge impact on families and on society," Cox said. Trauma is far and away the main cause of death and disability among children,...

New study examines how sense of smell affects mating and aggression in mice

...the nasal cavity and contains sensory neurons that recognize odors and transmit this information to the brain. The study is important, says Shah, because it establishes a novel and hitherto unsuspected role for the MOE in regulating mating and aggressive behavior in mice. He adds that while it appears humans ...

First big influenza genome study reveals flu evolution

... well as avian, equine, and swine flu isolates, to recognize influenza's patterns of genetic change. To do so, TIGR has built an innovative viral genomics lab, which is ramping up to sequence 100 influenza genomes weekly. Influenza poses a major public health problem. In an ordinary year, the flu kills up to...

By contrast, he added, the mice depleted of stathmin perform normally in a test of spatial learning. Fear reactions represent a spectrum of behaviors that vary from those that are inborn to those instilled...

K-State researchers study insects' immune system

...oal of their research is to understand how insects recognize infection caused by microorganisms such as viruses, bacteria and fungi, and the pathway of reactions that follow in the immune system. Studying the immune system of insects is important because it can lead to useful knowledge for the improvement of ...
