Structure solved by scientists at The Scripps Research Institute marks important milestone in effort to develop HIV vaccine

...invade cells. A further problem is that the virus sheds its cell surface gp120 and antibodies raised against this viral debris are ineffective against the intact virus. Thus, the shed viral proteins act as a decoy to divert the immune response from the virus itself. First identified in the bone marrow ...

Alcohol researchers show 'friendly' virus slows HIV cell growth

...is gratifying when the work of alcohol researchers sheds light on diseases other than alcoholism-especially diseases with consequences to individuals and society such as those of HIV-AIDS, the most far-reaching epidemic of our time."...

Hopkins researchers find missing link between major proteins in Parkinson's disease

... treatments, Dawson says. To begin with, the study sheds some light on how these three proteins normally interact. Parkin was already known to mark certain proteins for destruction by recruiting a fourth protein called ubiquitin. Synphilin was only known to bind to aS, whose normal function isn't understo...

Important step taken toward the identification of schizophrenia genes

... Veterans Administration Cooperative Study Sample, sheds new light on the confusing situation. It is the first such study to include large samples of European-American and African-American families from the United States. As a result, the researchers were able to determine that the association between chro...

Molecular insight into wound healing

...tion. Published in Genes & Development, this study sheds new light on the molecular mechanism of wound healing and identifies a potential new drug target in the treatment of skin disorders like psoriasis. The epidermis is the fist line of defense against injury and infection. When an injury is incurred, it...

New species clarifies bird-dinosaur link

... The fossil is more than 130 million years old and sheds light on dinosaurs during the transition from the Jurassic period to the Cretaceous period. Sinovenator changii (sigh-no-ven-ay-tor chang-eye) is a troodontid (tro-don-tid), a type of theropod (tare-a-pod). Although many theropods, such as Tyrannosau...

UCSF prion finding in mice leads team to urge similar study in cattle

...inal cord and lymphatic tissues. The current study sheds light on these possibilities. In their study, the researchers inoculated the brains of normal mice with either of two strains of mouse prions, known as the Me7 and the Rocky Mountain Laboratory strains. They discovered that the animals did, in fact, ...

Inhaled steroids produce variable benefits in the treatment of asthma

A new study sheds light on the differences in the way asthma patients respond to inhaled steroid therapy. This study conducted by the National Heart, Lung and Blood Institutes Asthma Clinical Research Network demonstrated that low to medium doses of inhaled steroids a...

NYU biologists develop better way to 'silence' neurons

... on a standard genetic technique. The new method sheds light on the central role electrical activity in neurons plays in governing the bodys circadian rhythms, or internal clock. It may also help in the future development of more effective treatments for diseases that are caused by aberrant electrical a...

Discovery sheds light on mechanisms that allow cells to steer directly toward chemical cues

...n a paper in the May 31 issue of the journal Cell, sheds light on the long-standing mystery of how cells are able to steer directly toward the source of chemical attractants, a process biologists call "chemotaxis." "Many cells within our body are able to sense chemical signals over long distances and move ...

UT Southwestern researchers shed new light on regulation of cell behavior

... transduction at the cell surface." The study also sheds light on the defect in limb-girdle muscular dystrophy, one of nine forms of the disease of which Duchenne is the most common. It is known that many limb-girdle patients have mutations in muscle-cell caveolin. The new study shows that these mutations ...

Joint Genome Institute to sequence key African frog genome

...r growth from eggs to tadpoles to mature organisms sheds light on the processes that guide the development of cells and organs. X. tropicalis was chosen for sequencing because its genetic structure is similar to humans but smaller and easier to decode than that of other frog species. "Frogs and other amph...

Sequence provides insights into a pathogen's virulence mechanism allowing for vaccine development

...agalactiae. "This study is important because it sheds light on the virulence mechanism of one of the last major human pathogens whose genome had not yet been sequenced," said Claire M. Fraser, TIGR's president. "This should help researchers find vaccine candidates or drug targets to fight a pathogen wit...

New Insight into cervical cancer development: turning it up a notch

...alignant cervical cancer development. This finding sheds new light on the role of Notch signaling in tumorigenesis, as previous research found that the activation of Notch promotes tumor development. Dr. Dotto explains that "The main conclusion that can be drawn from our findings is that the positive or ne...

Research reveals how an acid dissolves, molecule by molecule

...mation of the ozone hole, and Castleman's research sheds light on issues related to why such reactions occur at a rate much faster than expected. Although the dissolution of acids is one of the most fundamental chemical processes, its precise mechanism has remained a mystery for decades. Theoretical predi...

Genome of potential bioremediation agent sequenced

...c metals from the environment. The genome sequence sheds new light on the biochemical pathways by which the bacterium "reduces" and precipitates chromium, uranium and other toxic metals. The research offers what scientists call "a starting point" for defining the organism's electron transport systems and m...

Sandia-aided method to heal wounded and diseased achieves US government acceptance

...y pressure gauge to polyethylene, a substance that sheds adhesives. "The sensors are simple but not easy," said Vaughn. The external pressure gauge developed by Vaughn and Miller tests the tension of the Numobag wall, rather than puncturing it to directly test gas pressure. Because the Sandia researchers k...

Study helps explain gene silencing in the developing embryo

...- New research at the University of North Carolina sheds light on the process that silences a group of genes in the developing embryo. Down regulation of gene expression or "gene silencing" is considered crucial in normal development. In the embryo, proteins expressed by different sets of genes help signa...

James Nataroand colleagues of the University of Maryland School of Medicine weresearching for proteins that contribute to EAEC's success as a human pathogenas well as those that provoke a robust immu...

UT Southwestern researchers discover role of two genes involved in cholesterol excretion

...ute that cholesterol exits the body. The discovery sheds new light on potential therapies that could play an important role in reducing high cholesterol, a major risk factor of atherosclerotic diseases, such as coronary heart disease and stroke. The new findings are reported in this week's issue of the Pro...
