Nasal vaccine combats bird flu infection in rodents (Links to an external site)

Researchers at WashU Medicine have developed a nasal vaccine against the highly pathogenic H5N1 avian influenza virus, or bird flu, which has jumped from wild birds to livestock to humans. When tested in rodents, the vaccine elicited a strong immune response and prevented infections in animals exposed to H5N1.

Since it was first detected in the U.S. in 2014, H5N1 avian influenza, commonly known as bird flu, has jumped from wild birds to farm animals and then to people, causing more than 70 human cases in the U.S. since 2022, including two fatalities. The virus continues to circulate among animals, giving it the opportunity […]

Immunotherapy reduces plaque in arteries of mice (Links to an external site)

An immunotherapy reduces plaque in the arteries of mice, offering a potential new strategy to treat cardiovascular disease, according to a study led by WashU Medicine researchers. An artery from an untreated mouse (top) shows more plaque (orange) than that of a mouse treated with the antibody-based immunotherapy (bottom).

Scientists have designed an immunotherapy that reduces plaque in the arteries of mice, presenting a possible new treatment strategy against heart disease. The antibody-based therapy could complement traditional methods of managing coronary artery disease that focus on lowering cholesterol through diet or medications such as statins, according to the findings of a new study led […]

Breath carries clues to gut microbiome health (Links to an external site)

WashU Medicine and Children’s Hospital of Philadelphia researchers found that an analysis of compounds exhaled in breath can be used to infer which microbes are living in the gut, paving the way for a rapid, non-invasive breath test to monitor and diagnose gut health issues.

The human gut is home to trillions of beneficial microbes that play a crucial role in health. Disruptions in this delicate community of bacteria and viruses — called the gut microbiome — have been linked to obesity, asthma and cancer, among other illnesses.

Researchers at Washington University School of Medicine in St. Louis have uncovered why some patients with a rare genetic disorder called primary ciliary dyskinesia have worse lung problems than others with the same disorder. The discovery, published in Science Translational Medicine, suggests that gene therapy to restore a missing protein complex could help treat the […]

Innovative approach helps new mothers get hepatitis C treatment (Links to an external site)

Giving postpartum mothers with hepatitis C the opportunity to start antiviral treatment while still in the hospital after giving birth — and delivering the medication to their bedside before discharge — significantly increases their odds of being cured, according to a new study at WashU Medicine. (Image: Sara Moser/WashU Medicine)

Hepatitis C, a bloodborne virus that damages the liver, can cause cirrhosis, liver cancer, liver failure and death if left untreated. Despite the availability of highly effective treatments, the prevalence of hepatitis C infection remains high, particularly among women of childbearing age, who account for more than one-fifth of chronic hepatitis C infections globally. Within […]
