Exploiting unique features of the gut-brain interface to combat gastrointestinal cancer

摘要

The gastrointestinal tract comprises a complex ecosystem with extensive opportunities for functional interactions between neoplastic epithelial cells and stromal, immune, neuronal, glial, and other cell types, as well as microorganisms and metabolites within the gut lumen. In this Review, we focus on interactions between gastrointestinal cancers and elements of the central and enteric nervous systems. This previously understudied but rapidly emerging area of investigation has blossomed in recent years, particularly with respect to improved understanding of neural contributions to the development and progression of esophageal, gastric, pancreatic, and colon neoplasia. Cancer neuroscience offers great promise to advance our understanding of how neural-cancer interactions promote alimentary tract neoplasia. The resulting mechanistic insights can be leveraged to identify diagnostic and prognostic biomarkers, and to develop novel therapeutic interventions.
