“The power of mind” has long been a calling card of herbalists and mystics of all stripes. Most often, it should be taken with a big grain of salt. This week At the Lab, CSHL Professor Bo Li discusses new scientific research that could bring us closer to understanding the true connections between mind and body.

Sara Giarnieri: You’re now At the Lab with Cold Spring Harbor Laboratory. My name is Sara Giarnieri. And this week At the Lab, “Cleanup on IL-6.”
SG: That’s IL as in interleukin. We’ll get to that in a minute. But first, another common expression.
SG: Say what you will about the phrase “mind over matter.” New research from CSHL Professor Bo Li suggests that the connections between the brain and body may in fact be tighter than expected. And that could have big implications for cancer medicine.
SG: Li’s study focused on a lethal disease called cachexia, most often seen in late-stage cancer patients. It’s one of those medical conditions you might already know about without knowing its name. Li explains:
Bo Li: It occurs in a lot of cancer patients. In fact, most people with cancer die of cachexia instead of the tumor itself. And if we can somehow prevent or treat this syndrome, it will allow the patient to survive longer. The patient can undergo other therapies to treat the tumor. So, I think it’s going to have a big impact for many people.
SG: The idea is that many patients who develop cachexia can’t stand up to chemotherapy, radiation, or even surgery. So, treating or preventing cachexia could help ensure that they can get treatment.
SG: But where does IL-6 come in?
BL: Yeah, it’s a great question. Cancer cachexia has been studied for a long time. It has been known that interleukin-6 is important, but people don’t know why. We set out to study whether it is important for engaging the brain during cancer.
SG: Li and his colleagues identified the specific neural receptors in the brain that IL-6 overstimulates.
BL: And this is critical for the development of cachexia.
SG: So, figure out how to target the IL-6 receptors and you may someday be able to stop cachexia. As amazing as that sounds, this could be the start of something even more remarkable.
BL: It gives us an example of how disease is influenced by the brain. Simply changing a small number of neurons in the brain has a profound effect on whole-body physiology. So, theoretically, it’ll give us some understanding of how the brain really interacts with the body.
SG: That understanding could change how we think about the whole human experience. Thanks, IL-6!
