Lipid deposits (green) in brain immune cells (red) from mice with Alzheimer’s-like disease all but disappear (right) after the mice are treated with an experimental drug. Researchers at Washington University School of Medicine in St. Louis have found that a form of cholesterol known as cholesteryl esters builds up in the brains of mice with Alzheimer’s-like disease, and that clearing out the cholesteryl esters helps prevent brain damage and behavioral changes.

Kanta Horie, PhD, works with a mass spectrometer that he uses to measure protein levels in cerebrospinal fluid samples. Horie and colleagues at Washington University School of Medicine in St. Louis and Lund University in Sweden have discovered that a form of the protein tau in the cerebrospinal fluid known as MTBR-tau243 can be used to track the progression of Alzheimer's disease and could speed drug development.

A team of researchers at the McKelvey School of Engineering and the School of Medicine has developed a proof-of-concept air quality monitor that can detect live SARS-CoV-2 virus in indoor environments. The monitor uses a biosensor made with nanobodies that is integrated into an air sampler that operates based on the wet cyclone technology.

A new study by researchers at Washington University School of Medicine in St. Louis reveals that a connection between the body and mind is built into the structure of the brain. The study shows that parts of the brain area that controls movement are plugged into networks involved in thinking and planning, and in control of involuntary bodily functions such as blood pressure and heart rate.

When eyes are dry, the cornea is more susceptible to injury. By tracking the movements of stem cells (in fluorescent green) in a mouse eye, researchers were able to trace the cells as they differentiated into corneal cells and migrated to the center of the cornea, providing clues about how the cells work to help corneal injuries heal.
