New Lab-Grown Brain Cells Could Help Parkinson’s Research

Scientists have created a new type of lab-grown brain cell that may help in the fight against Parkinson’s disease. These cells, called Ncyte Microglia, mimic the immune cells found in the brain. Researchers hope they will make it easier to study Parkinson’s and test new treatments. What Are Microglia, and Why Do They Matter? Microglia are the brain’s immune cells. They help protect nerve cells, fight infections, and reduce inflammation. However, when they don’t function properly, they can cause neuroinflammation, which is believed to play a role in Parkinson’s and other brain diseases. The company Ncardia has developed Ncyte Microglia as a way to study these cells in the lab. Scientists can use them to test drugs and learn more about how inflammation affects the brain. How Are These Cells Made? Ncyte Microglia are created from stem cells—cells that can develop into almost any type of human cell. By using stem cells from healthy donors or Parkinson’s patients, researchers can create microglia that behave like the real thing. These lab-grown cells are frozen and can be used whenever needed. When thawed, they function like normal microglia, including: Detecting and responding to inflammation Releasing chemical signals (cytokines) Removing damaged cells and unwanted substances (a process called phagocytosis) Why Is This Important for Parkinson’s? Parkinson’s happens when certain brain cells (dopaminergic neurons) start dying. Scientists don’t fully understand why, but they believe inflammation—caused by malfunctioning microglia—plays a role. With this new microglia model, researchers can: Study how inflammation affects Parkinson’s Test potential treatments faster and more effectively Screen new drugs before moving to human trials Last year, Ncardia also launched a tool to test Parkinson’s treatments using dopaminergic neurons—the brain cells that die in Parkinson’s. This new microglia model adds another piece to the puzzle, helping scientists better understand the disease and work toward a cure.
