Another side to cancer immunotherapy? Emory scientists investigate intratumoral B cells

B cells represent the other major arm of the adaptive immune system, besides T cells, and could offer opportunities for new treatments against some kinds of Read more

Don’t go slippery on me, tRNA

RNA can both carry genetic information and catalyze chemical reactions, but it’s too wobbly to accurately read the genetic code by itself. Enzymatic modifications of transfer RNAs – the adaptors that implement the genetic code by connecting messenger RNA to protein – are important to stiffen and constrain their interactions. Biochemist Christine Dunham’s lab has a recent paper in eLife showing a modification on a proline tRNA prevents the tRNA and mRNA from slipping out Read more

Two birds with one stone: amygdala ablation for PTSD and epilepsy

It’s quite a leap to design neurosurgical ablation of the amygdala to address someone’s PTSD, and it was only considered because of the combination with Read more

Stem cell research center gets NSF support

Stem cell research is on the verge of impacting many elements of medicine, but scientists haven’t yet worked out the processes needed to manufacture sufficient quantities of stem cells for diagnostic and therapeutic purposes.

Todd McDevitt and Robert Nerem

The National Science Foundation (NSF) has awarded $3 million to Georgia Tech to fund a center that will develop engineering methods for stem cell production. The program’s co-leaders are Todd McDevitt, PhD, an associate professor in the Georgia Tech/Emory Department of Biomedical Engineering and Robert Nerem, director of the Emory/Georgia Tech Center for Regenerative Medicine (GTEC), which will administer the award.

“Successfully integrating knowledge of stem cell biology with bioprocess engineering and process development is the challenging goal of this program,” says McDevitt.

Summer undergrad research at Emory booming

This year’s Emory’s Summer Undergraduate Research Experience program is the largest it has ever been. Thursday’s poster session at the Dobbs University Center was split into two shifts so that all 99 participants could have a chance to explain their research. Graduate students in Emory’s Division of Biological and Biomedical Sciences circulated through the crowd, taking notes in order to judge the posters. The majority of participating students worked in biomedical research labs in the Woodruff Health Sciences Center.

SURE, organized by Emory’s Center for Science Education, is a ten-week program, attracting undergraduates not only from Emory but from other Atlanta-area universities and around the world.

Participants receive a stipend and on-campus housing, and have weekly meetings on ethics, research careers and lab life. About a third of former participants complete a graduate degree, according to follow-up surveys recently published in the journal Life Sciences Education. The main funding comes from Howard Hughes Medical Institute, with additional support from the National Science Foundation, National Institutes of Health and a variety of non-profit foundations.
