Despite lack of a key component of the immune system, a line of genetically engineered mice can control chronic herpes virus infections, researchers at the School of Medicine have found. Scientists suspect the missing component has a previously unrecognized backup that fills the void left by its absence. If so, that backup may become a new focus for efforts to design antiviral vaccines.

Abnormal folding patterns of the cerebral cortex in Williams Syndrome are displayed on a lateral view (left) and midline view (right) of a ‘surface-based’ atlas.A computerized atlas has brought unprecedented sensitivity to the search for brain structure changes in a genetic condition known as Williams syndrome, revealing 33 abnormalities in the folding of the brain’s surface. The disorder, which occurs in 1 in every 20,000 births, impairs visual and spatial skills but preserves musical ability and sociability.

Assab and Massawa, the two camels that produced antibodies for the caffeine testThree llamas and two camels have provided a way to tell whether your waiter swapped regular coffee for decaf in your after-dinner cup. Using the heat-resistant antibodies these camels and llamas make, researchers at the School of Medicine are developing a quick test for caffeine that works even with hot beverages. The researchers plan to adapt their technology to a simple test (“dipstick”) that can be used to check for caffeine in a variety of drinks.

Washington University in St. Louis will host a symposium May 30-31 to bring together people interested in developing new enterprises in Missouri based on research discoveries.

Robert Morley & Ed Richter investigated static electricity buildup from sliding down a plastic slide, which can temporarily silence the world to cochlear implantees.

Infectious disease experts at the School of Medicine and Barnes-Jewish Hospital will participate in a new multicenter research network dedicated to assessing, treating and preventing hospital-acquired infections.

Preliminary studies have shown that almost 50 percent of people who experience uncontrolled asthma symptoms have a chronic airway infection that they aren’t aware of. Now researchers at the School of Medicine are testing to see if treatment with an antibiotic will ease asthma symptoms in these patients.

If you’ve regularly been coughing, wheezing or short of breath, you may want to get tested for asthma at the Saint Louis Science Center on Saturday, May 20. As part of a nationwide program, Washington University School of Medicine and Barnes-Jewish Hospital physicians will be at the Science Center to test lung function and answer questions about asthma. The screenings are free.

Treating young children at high risk for asthma for two years with an inhaled steroid continually decreased asthma-like symptoms but did not prevent the disease after the medication was stopped, a study involving researchers at the School of Medicine shows.
