Cellular message movement captured on video

...enetically engineered proteins tagged with red and green fluorescence markers to the bovine aortic endothelial cells, grew them in tissue culture, and filmed them while they passed fluid across the cells’ surface in a simulation of flowing blood. With that physical stimulus, paxillin consistently moved in ...

Anthrax paralyzes immune cells with lethal toxin, UF research shows

... cell. As a result, immune cells never receive the green light to assemble the actin motor, Southwick's findings demonstrate. "Together, these studies provide important clues about how anthrax escapes the immune system during infection," said Nick Duesbery, Ph.D. deputy director for research operations ...

Newborn neurons like to hang with the 'in' crowd

...researchers injected a virus carrying the gene for green fluorescent protein into the hippocampus, a brain region harboring neural stem cells that give rise to new neurons. Newly born neurons infected with virus were marked by a fluorescent dye enabling the researchers to follow their fate over time as the...

Survival of the rarest: Fruit flies shed light on the evolution of behavior
