Scientists at The Scripps Research Institute have determined the structure of a critical protein from the Ebola virus, which, though rare, is one of the deadliest viruses on the planet killing between 50 and 90 percent of those infected. Described in the advance, online Early Edition of the journal Proceedings of the National Academy of Sciences (PNAS), the research reveals how a key component of the Ebola virus, called VP35, blocks the human immune system, allowing the virus uncontrolled replication. The structure represents a major step forward in understanding how the deadly virus works, and may be useful in the development of potential treatments for those infected. http://www.physorg.com/news179514235.html Medicine & Health Tue, 08 Dec 2009 17:14:32 EST news179514235 Pathogen recognition is the foundation of the body's immune response and survival against infection. A small cell-receptor protein called DC-SIGN is part of the immune system, and recognizes certain pathogens, including those responsible for Ebola, Dengue fever and HIV. How the molecule binds to pathogens has been unclear. http://www.physorg.com/news166785602.html Chemistry Tue, 14 Jul 2009 10:30:01 EST news166785602 (AP) -- A form of ebola virus has been detected in pigs for the first time, raising concerns it could mutate and threaten humans, scientists report. http://www.physorg.com/news166367280.html Medicine & Health Thu, 09 Jul 2009 14:08:20 EST news166367280 Researchers at the University of Texas Medical Branch at Galveston have discovered two biochemical pathways that the Ebola virus relies on to infect cells. Using substances that block the activation of those pathways, they've prevented Ebola infection in cell culture experiments - potentially providing a critical early step in developing the first successful therapy for the deadly virus. http://www.physorg.com/news164997495.html Medicine & Health Tue, 23 Jun 2009 17:39:10 EST news164997495 (AP) -- Scientists have identified a lethal new virus in Africa that causes bleeding like the dreaded Ebola virus. The so-called "Lujo" virus infected five people in Zambia and South Africa last fall. Four of them died, but a fifth survived, perhaps helped by a medicine recommended by the scientists. http://www.physorg.com/news162795409.html Medicine & Health Fri, 29 May 2009 05:57:55 EST news162795409 (AP) -- It was a nightmare scenario: A scientist accidentally pricked her finger with a needle used to inject the deadly Ebola virus into lab mice. Within hours, members of a tightly bound, yet far-flung community of virologists, biologists and others were tensely gathered in a trans-Atlantic telephone conference trying to map out a way to save her life. http://www.physorg.com/news157386912.html Medicine & Health Fri, 27 Mar 2009 15:36:27 EST news157386912 (PhysOrg.com) -- Researchers at the University of Pennsylvania School of Medicine have likely found one reason why the Ebola virus is such a powerful, deadly, and effective virus. Using a cell culture model for Ebola virus infection, they have discovered that the virus disables a cellular protein called tetherin that normally can block the spread of virus from cell to cell. http://www.physorg.com/news152290263.html Medicine & Health Tue, 27 Jan 2009 14:51:27 EST news152290263 Research led by Iowa State University scientists has them a step closer to finding a way to counter the Ebola virus. http://www.physorg.com/news150991288.html Biology Mon, 12 Jan 2009 14:01:28 EST news150991288
