The blind is off: Moderna COVID-19 vaccine study update

Amidst the tumult in the nation’s capital, a quieter reckoning was taking place this week for the Moderna COVID-19 vaccine clinical trial. Lab Land has been hearing from Emory-affiliated study participants that they’re finding out whether they received active vaccine or placebo. For example, Emory and Grady physician Kimberly Manning, who had written about her participation in the Moderna study in a Lancet essay, posted on Twitter Tuesday. She discovered she had received placebo, and Read more

Muscle cell boundaries: some assembly required

With cold weather approaching, many are digging out old jackets to find that the zippers don’t function as well as they used to. This is a good way to understand disruptions of muscle cell attachment studied by Emory cell biologist Guy Benian’s lab. 

Benian and colleagues have a paper on muscle cell biology in Nature Communications this week. In the worm C. elegans, they show how mutations cause junctions between muscle cells, which normally look like well-aligned zippers under the microscope, to either not form, or weaken and unravel. As a result, the mutant worms’ snake-like locomotion is impaired.

“This is yet another example in which research using the model genetic organism C. elegans has led to a new insight applicable to all animals, including humans,” Benian says. “Research on this organism has led to crucial advances in our understanding about development, cell death, aging and longevity, RNAi, microRNAs, epigenetics — and muscle.”
