Findings could help explain how asthma, COPD, severe COVID-19 are triggered

Study reveals details of how coronavirus infects heart; models of tissue damage may help develop potential therapies

Research involving cytokines and how they’re packaged sheds light on inflammation in asthma, COPD, COVID-19

New findings from researchers at Washington University School of Medicine in St. Louis suggest the eye’s cornea can resist infection from the novel coronavirus. Although the herpes simplex virus can infect the cornea and spread to other parts of the body in patients with compromised immune systems, and Zika virus has been found in tears […]

One of the most vexing aspects of the COVID-19 pandemic is the novel coronavirus’s ability to turn the body’s immune system against the body. After the virus has been cleared from the body, the immune system sometimes continues to hurtle an arsenal of immune proteins at the already vanquished virus, creating a dangerous inflammatory response […]

Researchers at Washington University School of Medicine in St. Louis are investigating whether a drug approved by the Food and Drug Administration (FDA) to treat rare diseases of an overactive immune system could help critically ill patients hospitalized with COVID-19. The drug blocks a specific protein of the immune system that doctors suspect contributes to […]

An experimental vaccine is effective at preventing pneumonia in mice infected with the COVID-19 virus, according to a study from Washington University School of Medicine in St. Louis. The vaccine, which is made from a mild virus genetically modified to carry a key gene from the COVID-19 virus, is described in the journal Cell Host […]

Washington University in St. Louis, the St. Louis County Department of Public Health and other collaborators are conducting a survey of St. Louis County residents and offering COVID-19 testing to gauge the prevalence of and risk factors for the illness. Working with the county, Washington University’s Institute for Public Health is teaming up with other local public health and […]

The virus that causes COVID-19 probably originated in wild bats that live in caves around Wuhan, China, and may have been passed to a second animal species before infecting people, according to the World Health Organization. Many of the most devastating epidemics of recent decades – including Ebola, avian influenza and HIV/AIDS – were triggered […]

As U.S. scientists ramp up a national effort to evaluate COVID-19 vaccine candidates at clinical trial sites across the country, researchers at Washington University School of Medicine in St. Louis and the Saint Louis University Center for Vaccine Development have been tapped to join the historic effort to find a COVID-19 vaccine that can prevent […]

Airborne and potentially deadly, the virus that causes COVID-19 can only be studied safely under high-level biosafety conditions. Scientists handling the infectious virus must wear full-body biohazard suits with pressurized respirators, and work inside laboratories with multiple containment levels and specialized ventilation systems. While necessary to protect laboratory workers, these safety precautions slow down efforts […]

The virus that causes COVID-19 probably originated in wild bats that live in caves around Wuhan, China, and may have been passed to a second animal species before infecting people, according to the World Health Organization.

Six months into the pandemic, people diagnosed with mild cases of COVID-19 still are told to isolate themselves and wait out the infection at home. Doctors monitor such patients so they can intervene if their condition deteriorates, but no antiviral drugs have been shown to hasten recovery or forestall severe illness in people who are […]

With Brazil leading the world in newly diagnosed COVID-19 cases, Latin America has become the epicenter of the coronavirus pandemic. Meanwhile, outbreaks continue to escalate in parts of Asia, Africa and the Middle East. Public health authorities worldwide desperately need to expand testing so they can track the spread of the infection, but molecular diagnostic […]

In the weeks before the St. Louis region saw its first patients with COVID-19, physician-scientists at Washington University School of Medicine began planning and preparing how best to collect blood and other biological samples from such patients so specimens could be quickly disseminated to researchers seeking strategies to treat, prevent and contain the novel coronavirus.

The global effort to quickly develop drugs and vaccines for COVID-19 has been hampered by limited numbers of laboratory mice that are susceptible to infection with SARS-CoV-2, the virus that causes COVID-19. Now, researchers at Washington University School of Medicine in St. Louis report they have developed a mouse model of COVID-19 that replicates the […]
