Pancreatic Lymphatics in Health and Disease: Evolution, Embryology, and Neural Control

Diseases of the pancreas-such as pancreatic ductal adenocarcinoma (PDAC) and pancreatitis-have long been a challenge to treat. The study of lymphatics within the pancreas can provide some additional insights and offer new therapeutic targets. Here, we explore the development of pancreatic lymphatics and their connections to the nervous system and individual disease states, as well as the potential for therapeutic interventions. Lymphangiogenesis pathways in PDAC, driven by VEGF-C and other mediators, have been extensively explored, but specific therapeutic interventions are lacking. Furthermore, due to the emergence of PDAC with pancreatitis, insights could improve treatment in both settings. The role of neuroimmune interactions and control, as in other organ sites, appears as critical to both lymphatic and immune processes. With a better understanding of the lymphatic environment within the pancreas, we can develop more effective treatments for patients.
