Researchers add new tool to tumor-treatment arsenal

... the "guardian of the cell" (a protein called p53) responds by either killing the cell, if the damage is too severe, or allowing the cancer cell to repair the damaged DNA. If the DNA is repaired, cells can continue to multiply. The dilemma is that high doses of DNA-damaging agents can be toxic, and doses tha...

Polymers with copper show promise for implanted sensors

...and biomedical engineers. The problem is, the body responds to these foreign objects in ways that interfere with their ability to accurately measure blood chemistry. In the bloodstream, clots form on the surface of implanted sensors or blood vessels contract around them. Sensors implanted under the skin may b...

New component of the 'brakes' on nerve regeneration found

... an important part of the receptor on neurons that responds to growth-inhibitory molecules in myelin. Specifically, these molecules prevent the growth of the cablelike axons of injured neurons. Myelin is the fatty sheath that encases neurons and acts as an insulator and aid to the transmission of nerve impuls...

Researchers identify protein crucial for survival of Lyme-disease bacterium

... causes Lyme disease lacks a specific protein that responds to an incoming meal of blood, it is unable to be transmitted from the tick to a new animal host, researchers at UT Southwestern Medical Center have found. The findings suggest that the protein, called BptA, is essential for the bacterium Borrelia bu...

Medical molecules designed to respond to visible light that can penetrate tissue

..., they changed the light absorber unit to one that responds to the red wavelength. "Investigations into polyazine supermolecular complexes containing Ru and Os with Rh centers that possess photoactive MMCT states: Visible light induced, oxygen independent DNA photocleavage (INOR 329)," will be presented by M...

A new way to share models of biological systems

...nected in complex ways to ensure that the organism responds appropriately to its environment. One of the best ways of ensuring that we really understand how these processes fit together is to build computer models of them. If a computer model behaves differently than the real organism, we know that we've negl...

Newly Discovered 'Branding' Process Helps Immune System Cells Pick Their Fights

...une system known as adaptive immunity. This branch responds to pathogens after they interact with the other major branch, the innate immune system. T cells kill pathogens or produce molecules like cytokines that stop their growth. Scientists have known for some time that a second class of innate immune syste...

At the molecular level, the predator is the prey

DOE JGI launches IMG public online microbial genome data clearinghouse

...ogical Research of the DOE Office of Science. "IMG responds to the urgent need of handling the vast and growing spectrum of datasets emerging from genome projects taken on by the DOE JGI and other public DNA sequencing centers. It is our hope that the IMG system will enable our scientists to tap the rich dive...

Specialized immune-system B cells play double-barreled role

... level of protection, while the other specifically responds to an infection to help eliminate it." According to Haas and Tedder, the findings offer potential insights into the mechanism of vaccine action. For example, the new insights into the roles of the two B-1 cell subtypes could help explain why the imm...

Scripps research scientists solve structure of a critical innate immune system protein

...cific molecules activates the immune system, which responds with a multi-stage biochemical defense starting with the unleashing of an army of white blood cells, like macrophages, which engulf and destroy pathogens. The macrophages also fight the pathogens by producing large amounts of chemicals that induce in...

Newly discovered genetic disease sheds light on body's water balance

...levels in cells by using a luciferase plasmid that responds to cAMP. Luciferase is the substance that lights up in fireflies. Feldman showed that wild-type cells contain low levels of light from luciferase -- and thus low levels of cAMP. In Feldman's experiments, cells with the R137C mutation proved to have...

Bees, Brains and Addiction

...ard. Computer models of how a bee assimilates and responds to information about a reward can be then applied to studies of how humans make decisions about rewards. And predictions from computer modeling of the bee brain can be tested via human brain imagining studies. For example, Sejnowski said that by usin...

"This is something that has not been done before, and has implications for human longevity and health." A paper on the subject by co-first authors Rea and Deqing Wu, in addition to James Cypser a...

Harmless virus may hold key to more effective HIV drug discovery

... Knowing how the entire population of Nef variants responds to new drugs gives researchers greater ability to identify broad-spectrum, anti-HIV compounds. This approach, Weiss said, can make drug discovery efforts for other anti-viral therapies faster and more effective. Study results appear in online versio...

Deep sleep short-circuits brain's grid of connectivity

Hide and seek: Researchers discover a new way for infectious bacteria to enter cells

...overed that when InlB interacts with Met, the cell responds by adding a chemical tag to Met that flags it for protein recycling or degradation. Since Met is on the outside surface of the cell and the recycling and degradation machineries are inside, the cell must bring Met inside through endocytosis in order ...
