Ebola outbreak in West Africa lends urgency to recently-funded research

Posted by Nicholette Zeliadt | Categories: Infectious diseases, Virology

Electron micrograph of Ebola virus

Earlier this year, the Ebola virus popped up for the first time ever in West Africa. How it got there, some 2,000 miles from previous Ebola hotspots in remote parts of Central Africa, remains a mystery. Experts are particularly concerned about the current outbreak, which has sickened more than 250 and killed at least 140, because the pathogen has made its way into Conakry, the densely populated capital city of Guinea.  Read more

Mouse study illustrates how foreign herpes DNA triggers immune response

For the immune system to do its job in fighting off disease, it first has to be able to detect foreign intruders. Scientists have known for some time that when bacteria, viruses and other pathogens set off alarms in the immune system, this leads to the production of molecules such as interferon that rev up the body’s defenses. But until now, researchers lacked evidence from animal experiments to back up the theory of how the DNA from these pathogens first triggers this immune-activating cascade in the immediate, ‘innate’ immune response.  Read more
