New IOM report assesses breast cancer risk posed by environmental factors

In the new study, researchers induced mice models with acute pancreatitis. As a result, the level of dendritic cells in the pancreas increased by two-fold. This observation identified the innate immune system response of dendritic cells to the excessive swelling and inflammation of the pancreas gland. In addition, researchers tested the effects of dendritic cell depletion in acute pancreatitis mice models. Their experiments showed mice with depleted dendritic cell levels developed pancreatic necrosis and died within four days. Dendritic cell depletion was also associated with a higher infiltration of white blood cells and inflammation markers. The negative effects of dendritic cell depletion experiments show the critical protective role these cells play in pancreatic organ survival.

"We now have a greater understanding of dendritic cells, the key cellular mediators of inflammation, during dangerous acute pancreatitis. These cells play a central role in acute pancreatitis and are required for the pancreas' viability," said Dr. Miller, a member of the NYU Cancer Institute. "Our novel findings show depletion of dendritic cells result in the massive increase in severe pancreas inflammation, injury and organ destruction. We are now one step closer to more effective treatments for this harmful human condition."

The study suggests dendritic cells in the pancreas as new therapeutic targets for reducing any cellular stress on the pancreas from pancreatitis. Further research is needed to elucidate dendritic cell function and develop an immune-directed therapy against acute pancreatitis.
