The paper describes how Venezuelan equine encephalitis virus (VEEV) interacts with its receptor, LDLRAD3. This is important because VEEV is an emerging mosquito-borne virus that causes fast-spreading outbreaks. There are no good therapies or preventives for VEEV encephalitis, […]

Nearly everyone gets infected with respiratory syncytial virus (RSV) repeatedly over the course of a lifetime, starting in childhood. Most times, people fight off the virus handily and only end up with a mild cold. But some people — most often young children experiencing their first infection or older adults whose immunity has waned — […]

Rift Valley fever virus causes economically devastating outbreaks of hemorrhagic fever in livestock such as sheep, goats and cattle. These mosquito-borne outbreaks lead to infection in people working with dead or dying animals, sometimes causing hundreds of human cases and dozens of deaths.

The virus that causes COVID-19 today is not the same as the one that first sickened people way back in December 2019. Many of the variants circulating now are partially resistant to some of the antibody-based therapeutics that were developed based on the original virus. As the pandemic continues, more variants inevitably will arise, and […]

Alphaviruses — mosquito-borne viruses that can trigger brain infections and arthritis — may have met their match. Researchers at Washington University School of Medicine in St. Louis have identified two antibodies that protect animals from disease caused by alphaviruses. The antibodies worked for every alphavirus tested, meaning they potentially could form the basis of treatments […]

Despite causing a surge in infections this summer that has resulted in thousands of hospitalizations and deaths, the delta variant of the virus that causes COVID-19 is not particularly good at evading the antibodies generated by vaccination, according to a study by researchers at Washington University School of Medicine in St. Louis.

The body’s so-called good cholesterol maybe even better than we realize. New research from Washington University School of Medicine in St. Louis suggests that one type of high-density lipoprotein (HDL) has a previously unknown role in protecting the liver from injury. This HDL protects the liver by blocking inflammatory signals produced by common gut bacteria.

COVID-19 therapies made from antibodies often are given to patients who are at high risk of severe illness and hospitalization. However, there have been nagging questions about whether such antibody therapies retain their effectiveness as worrisome new virus variants arise.

The first two COVID-19 vaccines authorized for emergency use by the Food and Drug Administration (FDA) employed a technology that had never before been used in FDA-approved vaccines. Both vaccines performed well in clinical trials, and both have been widely credited with reducing disease, but concerns remain over how long immunity induced by the new […]
