Snapshots of Life: Imperfect but Beautiful Intruder

RSV Particle

The striking image you see above is an example of what can happen when scientists combine something old with something new. In this case, a researcher took the Rous sarcoma virus (RSV)—a virus that’s been studied for more than century because of its ability to cause cancer in chickens and the insights it provided on human oncogenes [1, 2]—and used modern computational tools to generate a model of its atomic structure.

Here you see an immature RSV particle that’s just budded from an infected chicken cell and entered the avian bloodstream. A lattice of proteins (red) held together by short peptides (green) cover the outer shell of the immature virus, shielding other proteins (blue) that make up an inner shell.

Protecting Kids: Developing a Vaccine for Respiratory Syncytial Virus

Baby at the Doctor's OfficeVaccines are one of biomedicine’s most powerful and successful tools for protecting against infectious diseases. While we currently have safe and effective vaccines to prevent measles, mumps, and a great many other common childhood diseases, we still lack a vaccine to guard against respiratory syncytial virus (RSV)—a leading cause of pneumonia among infants and young children.

Each year, more than 2 million U.S. children under the age of 5 require medical care for pneumonia and other potentially life-threatening lower respiratory infections caused by RSV [1,2]. Worldwide, the situation is even worse, with more than 30 million infections estimated to occur annually, most among kids in developing countries, where as many as 200,000 deaths may result [3]. So, I’m pleased to report some significant progress in biomedical research’s long battle against RSV: encouraging early results from a clinical trial of an experimental vaccine specifically designed to outwit the virus.
