| Research recognition Burroughs Wellcome Fund recognizes three for infectious diseases research (http://mednews.wustl.edu/news/page/normal/11909.html) June 12, 2008 -- The Burroughs Wellcome Fund (BWF) has recognized three researchers at the School of Medicine for their studies of infectious diseases. Instructor Jeffrey Henderson will receive the BWF 2008 Career Award for Medical Scientists. Assistant professors David Wang and Dong Yu will each receive a 2008 BWF Investigators in Pathogenesis of Infectious Disease award. |
| Mental processes Researchers find that neurons compensate for electrical changes (http://mednews.wustl.edu/news/page/normal/11899.html) June 11, 2008 -- All mental processes, including thinking, learning and memory, depend on the electrical properties of individual nerve cells in the brain and on the connections between them. In turn, the electrical responses of each nerve cell, or neuron, reflect the unique set of pores — called ion channels — that perforate its surface and allow the passage of charged particles, or ions. So researchers at the School of Medicine were a little surprised when they saw no harmful effects in mice after eliminating an important type of potassium ion channel from neurons in the brain. |
| It takes two to tango Researchers identify proteins that make up specialized ion channels (http://mednews.wustl.edu/tips/page/normal/11825.html) June 3, 2008 -- Researchers at Washington University in St. Louis are the first to identify two proteins responsible for mechanosensitive ion channel activities in plant roots. Scientists have long known that plant cells respond to physical forces. Until now, however, the proteins controlling the ion channel response remained a mystery. |

| Bacteria Thrive in Inner Elbow; No Harm Done
The New York Times and 2 others May 23, 2008 -- WUSTL researchers Ruth E. Lay and Jeffrey I. Gordon, along with colleagues, comment on different kinds of bacteria that do not harm the human body, but in fact help it. |
| Nurturing Our Microbes
Science News Online March 3, 2008 -- Cover story on the impact gut bacteria have on our health includes the research of WUSTL microbiologist Jeffrey Gordon. |
| Plant-like protein underpins common parasites' ability to infect
DailyIndia.com (FL) and 7 others Jan. 10, 2008 -- WUSTL researchers led by WUSTL molecular microbiology professor David Sibley have revealed that Toxoplasma gondii, a common human parasite, uses a plant-like protein for signalling when to increase its numbers and when to be dormant. T. gondii is found in one in every four humans causing serious disease in patients with weakened immune systems. |
| Scientists find potential weakness in plague germ
Scientific American and 3 others Jan. 26, 2007 -- The germ that caused the plague epidemic that ravaged medieval Europe has a weakness that could help make a particularly dangerous form easier to treat, according to a study published on Thursday. There are periodic natural outbreaks of pneumonic plague like one that started in 2005 in the Democratic Republic of Congo. There also is acute concern terrorists could harness the bacterium as an airborne germ warfare agent to spread pneumonic plague. Writing in the journal Science, WUSTL scientists led by molecular microbiology professor William Goldman said experiments with mice showed that the onslaught of the bacterium slows markedly when the germ cannot use a key protein. |
| A common parasite's strongest asset: its stealth
The New York Times June 20, 2006 -- On paper, Toxoplasma gondii looks as if it ought to be the most famous parasite on earth. This single-celled pathogen infects over half the world's population, including an estimated 50 million Americans. Each of Toxoplasma's victims carries thousands of the parasites, many residing in the brain. As Toxoplasma spreads through the body, it invades cells. Unlike other pathogens, Toxoplasma can enter almost every type of cell in the bodies of thousands of host species. David Sibley, an associate professor of molecular microbiology at Washington University in St. Louis, said, ''It just sits there, and the host doesn't recognize it as a foreign body it should destroy.'' |
