Researchers at Washington University School of Medicine have shown that levels of a specific protein in the blood rise as amyloid plaques form in the brain. The discovery could pave the way toward a blood-based test to diagnose Alzheimer’s disease before symptoms appear.

A new School of Medicine study has shown that specific bacteria living in the upper small intestines of malnourished children play a causal role in stunted growth and other damaging side effects of malnutrition. The knowledge could lead to better therapies.

Researchers at Washington University School of Medicine have combined two types of immunotherapy into a single treatment that may be more effective and possibly safer than current immunotherapies for blood cancers.

Researchers at Washington University School of Medicine and the Saint Louis University Center for Vaccine Development have joined the effort to find a COVID-19 vaccine that can prevent the illness. Researchers at the universities expect to enroll about 3,000 participants in several COVID-19 vaccine trials.

To help efforts to find drugs and vaccines for COVID-19, researchers at Washington University School of Medicine developed a hybrid virus that will enable more scientists to enter the fight against the pandemic. The researchers genetically modified a mild virus.

A new study from Washington University School of Medicine has found that mice infected with Chikungunya virus get less sick and are less likely to transmit the virus to mosquitoes if they have healthy gut microbiomes.

A team of wildlife biologists and infectious disease experts, including some at the School of Medicine, propose in an article published in Science a decentralized, global wildlife biosurveillance system to identify animal viruses that have the potential to cause human disease – before the next pandemic emerges.

Parasitologist L. David Sibley at the School of Medicine is leading an international effort to find drugs to cure toxoplasmosis, a parasitic disease characterized by vision problems and brain complications.

An experimental drug for a rare, inherited form of amyotrophic lateral sclerosis (ALS) has shown promise in a phase 1/phase 2 clinical trial conducted at Washington University School of Medicine and other sites.

Researchers at Washington University School of Medicine in St. Louis and Georgia Tech are leading a study using computer algorithms to identify stressors on social media linked to the COVID-19 pandemic.
