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

A new trend in medicine: redefining disease

Paul Wolpe, PhD

You may have already heard that last month Emory held its fifth annual predictive health symposium “Human Health: Molecules to Mankind.” Researchers, physicians, health care workers and members of the community from throughout the country met to learn about intriguing research and provocative commentary by health care experts.

One of those experts, Paul Wolpe, director of the Emory Center for Ethics, says health care has changed as more and more aspects of ordinary life or behaviors are being redefined as medical. For example, being drunk and disorderly has become alcoholism. Now, virtually all of life is being redefined in biological terms, he says. And that, says Wolpe, has led to an increase in health care costs. We have an enormous amount of new things that we are calling illness, and we expect our health care system to treat them, he says. “We are creating a new category of disease called pre-symptomatic.”
