Pancreatic cancer is one of the deadliest cancers. A condition called pancreatitis, which is prolonged inflammation of the pancreas, increases the risk of getting this cancer. For over 100 years, scientists have known that both pancreatitis and pancreatic cancer involve many nerves. But only recently have we started to learn that these nerves may actively cause pain, increase inflammation, and help cancer grow through direct interactions with cancer cells but also indirect effects on the immune system. However, we still do not fully understand how this works, and there are no treatments yet that target these harmful nerve-cancer interactions.Our research focuses on a type of nerve cell called a nociceptor. These nerves sense pain and use a protein called Nav1.8 to send signals. A new drug that blocks Nav1.8 was recently shown to be safe and helpful in reducing pain after surgery. In our project, we will test whether blocking Nav1.8 can also reduce pancreatic inflammation and slow cancer growth. We will also study how damaged nerves affect the immune system. Our early data suggests that injured nerves can change certain immune cells called macrophages, causing them to block T cells from attacking the tumor. Our overarching goal is to find new ways to prevent and treat pancreatic cancer by targeting the nerves that drive pain and disease. We hope these treatments will ease pain, stop cancer from forming or growing, and help patients live longer.
