Inside your body, there’s a small organ called the pancreas. Even though it’s not very big, it has a very important job: it helps control how your body uses sugar. One of the ways it does this is by making insulin — a hormone that acts like a key, helping sugar move from your blood into your cells. Once sugar gets into the cells, your body can use it as energy.
The pancreas makes insulin using special cells called beta cells. If these cells don’t work properly or if there aren’t enough of them, your body can’t move sugar into the cells like it should. This leads to high sugar levels in the blood, which can cause a disease called diabetes. Diabetes can lead to serious health problems if not managed well.
Recently, scientists at Weill Cornell Medicine made an exciting discovery about beta cells. A group led by Dr. James Lo found that not all beta cells are exactly the same. In fact, there are four different types of them. This discovery could change how we understand and treat diabetes.
One of these four types, called “cluster 1,” stood out. These cluster 1 cells are the hardest workers. They produce more insulin than the other types and are better at helping the body process sugar. Because of their powerful abilities, the researchers called them the “superhero” cells.
To figure this out, the scientists used a method called single-cell transcriptomics. This tool helps researchers look at each cell one by one to see which genes are active. Genes are like instruction books inside each cell that tell the cell what to do.
By looking at which genes are turned on in each beta cell, the scientists could see which cells were doing the most to help control blood sugar.
The cluster 1 beta cells had more active genes related to making insulin and using sugar. They also had high levels of a protein called CD63. This protein works like a label, making it easier to spot these superhero cells under the microscope.
The research didn’t just stop with mice. The scientists checked human beta cells too and found similar types, including the superhero cluster 1 cells. This means what they found in mice could also be true for people.
They also noticed that in mice with obesity or diabetes, there were fewer of these superhero cells. When these special cells disappear or don’t work well, it becomes harder for the body to make enough insulin. That can lead to or worsen diabetes.
To test if these superhero cells could actually help, the scientists put more of them into diabetic mice. The results were promising — the mice had better blood sugar control. But when they put in the other kinds of beta cells, it didn’t work as well. This shows that the superhero cells are especially good at fighting high blood sugar.
In the future, this could lead to new treatments for diabetes. If doctors can find a way to protect or increase these powerful beta cells, they might help people with diabetes manage their condition more easily. Dr. Lo’s team is now working to understand why people with diabetes lose these superhero cells and how we might stop that from happening.
They also want to see how current diabetes medicines affect the different types of beta cells. Maybe some medicines work better on certain cell types than others. Learning more about these cells could help scientists make better drugs and treatments in the future.
Alongside this research, other studies have shown that lifestyle choices can also help manage diabetes. Eating more whole grains and blueberries, and getting enough vitamin D, may help control blood sugar and blood pressure in people with diabetes.
This discovery about different kinds of beta cells — especially the superhero ones — is an exciting step forward. It gives hope to millions of people around the world living with diabetes. Thanks to the hard work of scientists, we are slowly getting closer to better treatments, and possibly even ways to prevent the disease altogether.
