Unique binding of Delta variant may explain high transmissibility
Peer-Reviewed Publication
Unlike other SARS-CoV-2 variants, the Delta variant can attach to copies of itself, forming larger aggregations, or clumps, of viral particles, suggests a study by scientists at the National Institutes of Health. The researchers theorize that this linking property may have played a role in the ability of the Delta variant to spread more rapidly than all the variants that preceded it.
A vaccine for eastern equine encephalitis virus (EEEV), western equine encephalitis virus (WEEV), and Venezuelan equine encephalitis virus (VEEV) was found to be safe, well-tolerated and induced a neutralizing antibody response in adult volunteers, according to newly published results from a Phase 1 clinical trial. The vaccine candidate was developed by scientists at the National Institute of Allergy and Infectious Diseases (NIAID) Vaccine Research Center (VRC), part of the National Institutes of Health. NIAID also sponsored and funded the clinical trial, which was conducted at the Emory Vaccine Center’s Hope Clinic, part of Emory University in Atlanta. The study appears online today in The Lancet Infectious Diseases.
A new online resource will help healthcare professionals and practices improve care for people whose alcohol consumption may be impacting their health. Recognizing alcohol’s contribution to over 200 diseases and conditions will improve clinicians’ ability to serve their patients. The Healthcare Professional’s Core Resource on Alcohol was developed by the National Institute on Alcohol Abuse and Alcoholism (NIAAA), part of the National Institutes of Health.
Women who experienced complications related to developing high blood pressure, or hypertension, during pregnancy had a 63% increased risk for developing cardiovascular disease later in life, according to research funded by the National Heart, Lung, and Blood Institute (NHLBI), part of the National Institutes of Health.
Researchers have identified distinct differences among the cells comprising a tissue in the retina that is vital to human visual perception. The scientists from the National Eye Institute (NEI) discovered five subpopulations of retinal pigment epithelium (RPE)—a layer of tissue that nourishes and supports the retina’s light-sensing photoreceptors. Using artificial intelligence, the researchers analyzed images of RPE at single-cell resolution to create a reference map that locates each subpopulation within the eye. A report on the research published in Proceedings of the National Academy of Sciences.
