Dopa decarboxylase and angiotensin converting enzyme 2 immunoexpression in the gastrointestinal tract of control female Wistar rats - a pilot study.

Studies have shown important interactions between the local renin-angiotensin and monoaminergic systems in physiology and pathophysiology. Yet the understanding of such interactions in the gastrointestinal (GI) tract and GI-associated diseases is the least understood. Thus, the aim of our study was to characterize the expression pattern of DDC and ACE2 along the GI tract (duodenum, jejunum, ileum, and colon) of control female Wistar rats.
