Type 2 Diabetes: Overactive Cell Link
University of Missouri researchers are actively targeting chemoreceptors to discover novel therapies for type 2 diabetes and cardiovascular disease. Their analysis reveals how overactive chemoreceptors near the carotid artery may signal increased risks. The study examined whether increased oxygen could manipulate activity, aiming to improve cardiovascular health. Individuals with type 2 diabetes displayed heightened chemoreceptor activity, wich decreased with high oxygen exposure, though no immediate glucose or insulin gains were seen.This critical research is a step forward in understanding the link between chemoreceptors and metabolic consequences.

Missouri Researchers Target chemoreceptors in Diabetes, Cardiovascular Disease Study
Updated June 16, 2025
COLUMBIA, Mo. — University of Missouri scientists are exploring new avenues for treating cardiovascular and metabolic conditions, including high blood pressure and type 2 diabetes. Their research focuses on specific cells that may contribute to these disorders.
A recent study examined chemoreceptors, cell clusters near the carotid artery in the neck.overactivity in these chemoreceptors can signal a higher risk of cardiovascular problems and mortality. Because these receptors are sensitive to oxygen levels, researchers investigated whether manipulating oxygen could influence their activity and, potentially, improve cardiovascular and metabolic health.
Jacqueline Limberg, an associate professor of nutrition and exercise physiology at MU, noted promising results in animal studies. “There are exciting studies in rats that show removing these chemoreceptors when they become overactive can improve issues like high blood pressure and high blood sugar,” Limberg said. The team explored whether high doses of oxygen might reduce chemoreceptor activity, offering a less invasive approach than removal.
The study involved 17 participants with type 2 diabetes and a control group of 20 without the condition. Researchers found that chemoreceptors were indeed more active in individuals with diabetes,with the highest activity levels observed in those with elevated blood sugar.
When participants were exposed to hyperoxia,a state of high oxygen levels,chemoreceptor activity decreased,along with heart rate,blood pressure,and breathing rate. Though, these effects were similar in both groups, and there was no immediate change in glucose tolerance or insulin sensitivity.
Camila Manrique-Acevedo, a professor of medicine at MU, emphasized the study’s importance in understanding the link between chemoreceptors and type 2 diabetes. “The goal of this study was to understand how peripheral chemoreceptors affect the cardiovascular and metabolic consequences of type 2 diabetes,” Manrique-Acevedo said. “We now understand one bout of hyperoxia does not promptly improve function. having this information allows us to focus our attention on other therapies that show promise for patients with type 2 diabetes.”
What’s next
researchers will now focus on alternative therapies that may offer more effective solutions for managing type 2 diabetes and related cardiovascular complications.
