Synthetic cellular machinery

ERIK CARLSONScientists from the University of Illinois, Chicago, have synthesized ribosomes composed of two designer subunits for the purposes of learning more about how these cellular machines work and for potential synthetic biology applications. Their results were published in Nature this week (July 29).

“It’s a key advance in understanding ribosome [function] and also in establishing a path to fundamentally alter the catalytic center of the ribosome . . . which will really allow you to start introducing new types of chemistries [and] producing entirely new classes of synthetic polymers,” said Farren Isaacs of Yale University who was not involved in the work.

“This was not a casual weekend experiment. This was a major effort,” said Harry Noller of the University of California, Santa Cruz, who also was not involved in the research.

Lack of funding stalls MERS research

“You have to get support from either a company or a foundation to push [vaccines or monoclonal antibodies] into clinical studies,” immunologist Shibo Jiang of the New York Blood Center told The Scientist.

The funding problem extends beyond MERS. And researchers expect other emerging infectious diseases to take the world by surprise. “There’s going to be other emerging infectious diseases on the horizon,” said Barney Graham, deputy director of the Vaccine Research Center at the National Institute of Allergy and Infectious Diseases, who led the Nature Communications study. “The world needs a better mechanism to be able to respond to emerging diseases in a more organized and systematic way.”

Reconstructing ancestral AAVs

LIVIA CARVALHOIn an attempt to develop immune system-evading adeno-associated virus (AAV) vectors for gene therapies, a team led by scientists from the Schepens Eye Research Institute and the Massachusetts Eye and Ear Infirmary in Boston has looked to the viruses’ past. Reconstructing ancestral AAVs, the group found they did not elicit signs of immune rejection when delivered to mammalian tissues. The results were published in Cell Reports this week (July 30).

“This is a very thorough, creative, and carefully done study,” said Jean Bennett of the University of Pennsylvania who has collaborated with study lead Luk Vandenberghe, but was not involved in the work. “The ancestral AAVs have promise with respect to use, although, ultimately, human testing would reveal their utility.”
