Three Dimensional Images of the AIDS Virus

As the world marks the 25th year since the first diagnosed case of AIDS, groundbreaking research by scientists at Florida State University has produced remarkable three-dimensional images of the virus and the protein spikes on its surface that allow it to bind and fuse with human immune cells.

Findings from this AIDS research could boost the development of vaccines that will thwart infection by targeting and crippling the sticky HIV-1 spike proteins. In fact, said principal investigator and FSU Professor Kenneth H. Roux, at least two laboratories already are crafting vaccine candidates based on preliminary results uncovered by his team of structural biologists.

Those results are described in the online edition of the journal Nature.

Never before generated in such intricate detail, the super-sized images of the virus and its viral spikes have given researchers their first good look at the pathogen's complex molecular surface architecture that facilitates the infection process.

"Until now, despite intensive study by many laboratories, the design details of the spikes and their distribution pattern on the surface of the virus membrane have been poorly understood, which has limited our understanding of how the virus infection actually occurs and frustrated efforts to create vaccines," Roux said.
