Scientists have found that nerves are involved in pancreatic cancer development even before tumors form. This discovery could lead to new treatment strategies.

Pancreatic cancer is one of the most difficult cancers to diagnose early, and it often does not respond well to standard treatments. Researchers at Cold Spring Harbor Laboratory (CSHL) have made a significant breakthrough in understanding how pancreatic cancer develops. They found that nerves are involved in the process even before tumors form.

The researchers used advanced 3D imaging to visualize interactions between tumor-promoting fibroblasts and nerve fibers. They discovered that these fibroblasts release chemical signals that attract nearby nerve fibers. Once present, the fibroblasts and nerve cells interact inside pancreatic lesions, helping create conditions that support cancer growth.

The study found a harmful cycle between myCAFs (tumor-promoting fibroblasts) and nerves. The myCAFs release signals that draw in nerve fibers from the sympathetic nervous system, which controls the body's fight or flight response. Those nerve fibers release norepinephrine, a neurotransmitter that binds to the fibroblasts and causes a spike in calcium levels inside the cells.

The researchers also tested what would happen if this nerve activity were interrupted. They found that blocking nerve signals slowed down tumor growth by nearly 50%. This discovery could lead to new treatment strategies for pancreatic cancer.

Why It Matters

This research is important because it could lead to more effective treatments for pancreatic cancer, which is a major health concern in India. Understanding the role of nerves in cancer development could help doctors develop new therapies that target this process.
