Vaccine-producing 'plant-factories'

...mmunise against diseases. Moreover, this discovery opens the door to the design of protein-manufacturing plants of great interest therapeutically and in the development of vaccine antigens. This discovery, published in the latest issue of The Plant Cell, contributes, moreover, to refuting one of the curre...

Male contraception: One door opens, another closes

...ent of one hot new lead and one dead end. A door opens Researchers in Italy and at the Population Council in New York have announced a breakthrough on a non-hormonal compound known as Adjudin (Nature Medicine, Oct. 29). By injecting the compound as an attachment to a modified hormone that seeks out t...

Fantastic Voyage: A new nanoscale view of the biological world

...t significant feature of this technique is that it opens up a whole new world of imaging; we haven't yet imagined all that we can do with it," says Peter Gillespie from the Oregon Health and Science University in Portland, USA in an accompanying news article, also published today in Journal of Biology. ...

Scientists crack genetic secrets of human egg

... genes unique to the human egg. The identification opens the way to understanding these genes' functions, which may lead to solving problems from infertility to degenerative diseases. "What's in the egg to have that power?" asked Jose Cibelli, MSU professor of physiology and animal science. "Some of thos...

Clue found to Epstein-Barr virus' ability to form and sustain tumors

...ublic Health (SMPH) have found a viral target that opens the door for the development of drugs to destroy tumors caused by Epstein-Barr virus (EBV). The finding, published in the Sept. 4 Proceedings of the National Academy of Sciences Online, identifies the activity of a critical segment of a viral prote...

Natural protein stops deadly human brain cancer in mice

Researchers create mouse lacking key inflammation gene

...of the macrophage-specific LITAF-deficient animals opens new opportunities for assessing the role of LITAF in inflammation in hopes of designing anti-LITAF drugs for major inflammatory diseases," says Dr. Salomon Amar of Boston University, the lead author of the paper. Amar discovered the LITAF transcripti...

Ebola-outbreak kills 5000 gorillas

...gorilla social group to gorilla social group. This opens the door to targeted vaccination strategies that, by breaking the chain of transmission, could be much more efficient than in the case of outbreaks driven entirely by reservoir spillover. The consistent spread rate of the Ebola infection wave also su...

Wild gorillas carriers of a SIV virus close to the AIDS virus

... might have contaminated humans". This work thus opens up a Pandora's box on the questions and speculations concerning the ability of these viruses to cross over from one species to another. The main challenges facing these teams for future work will be determination of the prevalence, the geographical d...

'Allergy cells' can aggravate cancer and psoriasis

...eptors on the surface of the mast cell, which then opens and secretes part of its contents. In the past few years it has emerged that mast cells, which are a type of immune cell, are probably also involved in the development of a number of other diseases, like atopical eczema, psoriasis, and the Hodgkins...

Molecular 'signature' protects cells from viruses

...ulate an immune reaction and initiate cell suicide opens up completely new perspectives for the therapy of virus infections and cancer cases: for example, RNA chains with a triphosphate end could be produced and fed into cancer cells. This could also trigger an anti-viral immune response. 'Our findings are...

Ferns provide model for tiny motors powered by evaporation

...pine of the device. In this way, the closed device opens wide---it moves. They plan to add electrical components to the device in an attempt to generate electricity. They predict that the device will be able to generate the same amount of electricity as other scavenging devices, say, a solar cell in a cal...

Worms produce surprise insight into human fever

...or treating neurodegenerative diseases. “Our work opens the possibility of using co-inducers of HSF-1 to boost immunity to treat infectious diseases and immunodeficiencies,?says Aballay. ...

Does natural selection drive the evolution of cancer?

...nown as apoptosis. Seeing a tumor in this light opens a window on new therapeutic strategies. "It's not just a metaphor to say tumor cell populations are evolving," Maley says. "Evolution is going on in the tumor. So let's think about how we might want to influence that evolution. Can we push it down...

Biofuel cells without the bio cells

...ering sewage treatment plant. Using pure protein opens up the possibility of shrinking biofuel cells to power small electronic devices, Squier said. Whole-organism biofuel cells require engineers to design a space-adding membrane that prevents unwanted reactions between fuel, the charge-transporting agen...

Researchers find docking sites for glucocorticoid receptor and Hsp90

...terminal domain of Hsp90," she said. "This finding opens the possibility to develop small molecules that block specific Hsp90-client protein interactions. As part of our work, we also have identified GR mutants that are able to bind hormones without Hsp90, which may facilitate the development of novel synt...

Three-dimensional, miniature endoscope opens new diagnostic possibilities

Standard miniature endoscopic devices ?which give physicians access to hard-to-reach internal organs and structures ?utilize bundles of optical fibers to supply light to and transmi...

Study offers innovative profile of enzyme that aids tumor growth

...erimental strategy. "The success of our study opens the door to assembling the full range of enzymes into both metabolic and signaling networks contributing to complex pathologies like cancer," Cravatt said. "This could lead to the discovery of new markers for diagnosis and targets for treatment." ...

Microcapsules like it hot and salty

... (Physical Review Letters, November 3, 2006). This opens up new possibilities for using the capsules to transport active substances in the body, as components of self-repairing car paints or as microsensors and micropumps. Ideally, medicines should only go to the sick regions of the body to prevent side...
