Washington University School of Medicine in St. Louis is a testing site for the Janssen Pharmaceutical Companies of Johnson & Johnson’s phase 3 clinical research study, called the ENSEMBLE trial, to evaluate the safety and efficacy of Janssen’s investigational COVID-19 vaccine candidate, JNJ-78436735, also known as Ad26.COV2.S.
Immune modulator drugs for COVID-19 focus of major NIH clinical trial (Links to an external site)
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 […]
Role of gut viruses in inflammatory bowel disease is focus of $8.5 million grant (Links to an external site)
The communities of bacteria that live in our digestive tracts help digest food and produce vitamins, protect against pathogens, and promote the healthy functioning of our immune system. But alongside gut bacteria thrives a vast community of viruses, and we know little about their impact on health and disease.
Study provides insight on how to build a better flu vaccine (Links to an external site)
Flu season comes around like clockwork every year, and sooner or later everyone gets infected. The annual flu shot is a key part of public health efforts to control the flu, but the vaccine’s effectiveness is notoriously poor, falling somewhere from 40% to 60% in a typical year.

Nasal vaccine against COVID-19 prevents infection in mice (Links to an external site)
Scientists at Washington University School of Medicine in St. Louis have developed a vaccine that targets the SARS-CoV-2 virus, can be given in one dose via the nose and is effective in preventing infection in mice susceptible to the novel coronavirus. The investigators next plan to test the vaccine in nonhuman primates and humans to […]
Major weight loss — whether from surgery or diet — has same metabolic benefits (Links to an external site)
Gastric bypass surgery is the most effective therapy to treat or reverse type 2 diabetes in severely obese patients. Many achieve remission of diabetes following surgery and no longer require diabetes medications. This observation has led to the theory that gastric bypass surgery has unique, weight loss-independent effects in treating diabetes, but this has remained […]

Global wildlife surveillance could provide early warning for next pandemic (Links to an external site)
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 […]

Many children treated for childhood malnutrition in developing countries never fully recover. They suffer from stunted growth, immune system dysfunction and poor cognitive development that typically cause long-term health issues into adulthood.
2 immunotherapies merged into single, more effective treatment (Links to an external site)
Some of the most promising advances in cancer treatment have centered on immunotherapies that rev up a patient’s immune system to attack cancer. But immunotherapies don’t work in all patients, and researchers have been searching for ways to increase their effectiveness.
Gut bacteria protect against mosquito-borne viral illness (Links to an external site)
Chikungunya virus, once confined to the Eastern Hemisphere, has infected millions of people in the Americas since 2013, when mosquitoes carrying the virus were discovered in the Caribbean. About half of all people infected with chikungunya virus never show symptoms, while some develop fever and joint pain that lasts about a week, and 10% to […]
COVID-19 vaccine trials to be conducted at Washington University, Saint Louis University (Links to an external site)
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 […]
Lab-made virus mimics COVID-19 virus (Links to an external site)
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 […]

Effort to screen potential COVID-19 antiviral drugs underway (Links to an external site)
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 […]
Stroke survival rates worse in rural areas, study says (Links to an external site)
A major U.S. study reveals large gaps between urban and rural patients in quality of care received after a stroke and rates of survival. In more rural areas, the ability of hospitals to deliver advanced stroke care is lower and mortality rates substantially higher, the research shows.

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.
COVID-19 mouse model will speed search for drugs, vaccines (Links to an external site)
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 […]

Using induced pluripotent stem cells produced from the skin of a patient with a rare, genetic form of insulin-dependent diabetes called Wolfram syndrome, researchers transformed the human stem cells into insulin-producing cells and used the gene-editing tool CRISPR-Cas9 to correct a genetic defect that had caused the syndrome. They then implanted the cells into lab mice […]
