Secrets to antibody's success against West Nile Virus surprise scientists

...were simultaneously exposed to antibodies known to enhance infection. "Do the therapeutic antibodies also prevent the virus from properly injecting its genetic material into macrophages? It's a tempting possibility, but we don't have the evidence to prove it yet," he says. ...

For first time, brain cells generated in a dish

...overy can translate to human applications, it will enhance efforts aimed at finding ways to use large numbers of a person's own cells to restore damaged brain function, partially because the technique produces cells in far greater amounts than the body can on its own. In addition, the discovery pinpoints th...

... whether mutations in the genes for these proteins enhance their normal action. "Importantly, such insights can now guide studies that focus on the normal function and interactions of these proteins and how they might be enhanced by disease-causing mutations," said Zoghbi. "These studies could give better u...

Study shows how retinoic acid enters a cell's nucleus
