More NMDA but less excitotoxicity? Now possible

Many researchers have wanted to enhance NMDA receptor signals to treat disorders such as schizophrenia. But at the same time, they need to avoid killing neurons with “excitotoxicity”, which comes from excess calcium entering the Read more

Update on pancreatic cancer: images and clinical trial

In 2018, Winship magazine had a feature story on pancreatic cancer. Our team developed an illustration that we hoped could convey the tumors’ complex structure, which contributes to making them difficult to treat. Oncologist Bassel El-Rayes described how the tumors recruit other cells to form a protective shell. "If you look at a tumor from the pancreas, you will see small nests of cells embedded in scar tissue," he says. "The cancer uses this scar Read more

Why malaria vaccine development is hard

In recognition of World Malaria Day, Lab Land will have a series of posts from Taryn McLaughlin, a graduate student in Emory’s IMP program. Her posts will set the stage for upcoming news about malaria research at Emory and Yerkes. Taryn is part of Cheryl Day’s lab and is also an associate producer with the AudiSci podcast.

Those of us in the US are fortunate to not have to consider malaria in our day-to-day lives. Globally though, malaria is a serious public health threat with nearly 3.2 billion people at risk and close to half a million deaths every year. The scientific community has been developing malaria vaccines for decades. Yet a robust vaccine still remains elusive. Why?

One set of barriers comes from economics: malaria’s strongest impact is in developing countries. But there is just as strong a case to be made for scientific obstacles. Frankly, the parasite (technically a bunch of species of microbes that I’ll just lump together under the umbrella term Plasmodium) that causes malaria is just smarter than we are.

I’m only kidding, but it is a fascinating organism. Its complexity makes it difficult to pin down and also interesting to write about. But before we talk about why Plasmodium is such a pain, let’s first discuss what exactly makes an effective vaccine. Read more
