Olena Shtanko, Ph.D., a Staff Scientist at the Texas Biomedical Research Institute (Texas Biomed), has received more than $1 million from the National Institutes of Health (NIH) to explore different aspects of Ebola virus infection.
What exactly triggers a sneeze? A team led by researchers at Washington University School of Medicine in St. Louis has identified, in mice, specific cells and proteins that control the sneeze reflex. Better understanding of what causes us to sneeze — specifically how neurons behave in response to allergens and viruses — may point to treatments capable of slowing the spread of infectious respiratory diseases.
In a study published today in the Annals of Internal Medicine, Johns Hopkins Medicine researchers say they believe that, for the first time, there is evidence to show that three doses of vaccine increase antibody levels against SARS-CoV-2 — the virus that causes COVID 19 — more than the standard two-dose regimen for people who have received solid organ transplants.

Scientists at Washington University School of Medicine in St. Louis have implicated a type of immune cell in the development of chronic lung disease that sometimes is triggered following a respiratory viral infection. The evidence suggests that activation of this immune cell serves as an early switch that, when activated, drives progressive lung diseases, including asthma and chronic obstructive pulmonary disease (COPD).

The study is published in the print version of the American Journal of Respiratory and Critical Care Medicine.
Using venom from the Conus nux, a sea snail, a first-of-its-kind study suggests these conotoxins could potentially treat malaria. The study provides important leads toward the development of new and cost-effective anti-adhesion or blockade-therapy drugs aimed at counteracting the pathology of severe malaria. Similarly, mitigation of emerging diseases like COVID-19 also could benefit from conotoxins as potential inhibitors of protein-protein interactions as treatment. Venom peptides from cone snails has the potential to treat myriad diseases using blockage therapies.
The study also showed that the number of COVID-19 infections in pregnant patients from nearly all communities of color in Washington was high. There was a twofold to fourfold higher prevalence of pregnant patients with COVID-19 infections from communities of color than expected based on the race-ethnicity distribution of pregnant women in Washington in 2018.

Newborns and young infants are particularly susceptible to the flu and are six times more likely to die from the infection than older children. Currently there is no flu vaccine available for babies less than 6 months old.
Artificial light abnormally increases mosquito biting behavior at night in a species that typically prefers to bite people during the day, according to research from the University of Notre Dame that was published in The American Journal of Tropical Medicine and Hygiene.
At night in a Ugandan forest, a team of American and African scientists take oral swabs from insect-eating cyclops leaf-nosed bats. In a necropsy room near the Baltic Sea, researchers try to determine what killed a donkey, a Bennett’s tree-kangaroo and a capybara at a German zoo — all of them suffering from severe brain swelling. Neither team was aware of the other, yet they were both about to converge on a discovery that would forever link them — and help solve a long-enduring mystery.
In a new study, infectious disease researchers show that HIV viremia isn’t always nonadherence to medication or resistance to the drugs. Instead, the patients are victims of what the scientists have dubbed “repliclones” – large clones of HIV-infected cells that produce infectious virus particles.
In a new study, researchers at La Jolla Institute for Immunology (LJI) report that a protein called TL1A drives fibrosis in several mouse models, triggering tissue remodeling, and making it harder for lungs and airways to function normally.
In a new Immunity study, researchers at La Jolla Institute for Immunology (LJI) show that one way to improve the body's immune response to vaccines is to factor in antigen valency. Valency refers to the number of antibody binding sites on an antigen.
Scientists have developed an injectable drug that blocks HIV from entering cells. They say the new drug potentially offers long-lasting protection from the infection with fewer side effects.
Scientists at Johns Hopkins Medicine, experimenting with a small number of human cell samples, report that the “hook” of cells used by SARS-CoV-2 to latch onto and infect cells is up to 700 times more prevalent in the olfactory supporting cells lining the inside of the upper part of the nose than in the lining cells of the rest of the nose and windpipe that leads to the lungs. These supporting cells are necessary for the function/development of odor-sensing cells. The findings, from a preliminary study of cells lining both the nose and trachea, could advance the search for the best target for topical or local antiviral drugs to treat COVID-19, and offers further clues into why people with the virus sometimes lose their sense of smell.
Mayo Clinic and collaborators have published a preprint that identifies two main signals of efficacy that can inform future clinical trials on plasma therapy on COVID-19 patients. The data are extracted from the Mayo-led national Expanded Access Program (EAP) for convalescent plasma for the treatment of hospitalized patients with COVID-19.
The National Institutes of Health will soon launch a phase II clinical trial to evaluate the safety and efficacy of potential new therapeutics for COVID-19, including the use of investigational synthetic monoclonal antibodies. Davey Smith of UC San Diego is the protocol chair and answers questions.

The mechanisms of action of acalabrutinib led to the hypothesis it might be effective in reducing the massive inflammatory response seen severe forms of COVID19. Indeed, it did provide clinical benefit in a small group of patients by reducing their inflammatory parameters and improving their oxygenation.
