Epithelial signaling is a research area that focuses on the communication and signaling processes within epithelial cells. Epithelial cells are a type of cell found in the outer layer of tissues and organs in the body, and they play a crucial role in maintaining the barrier function of these tissues. The signaling pathways within epithelial cells regulate important biological processes such as cell proliferation, differentiation, and migration. Research in this area aims to understand how these signaling mechanisms are dysregulated in diseases such as cancer, inflammation, and autoimmune disorders, and how they can be targeted for therapeutic interventions. By studying epithelial signaling, researchers hope to improve our understanding of various diseases and develop novel treatments to improve patient outcomes.
