In the metaplasia–dysplasia–carcinoma sequence of Barrett’s esophagus (BE) to high-grade dysplasia BE and esophageal carcinoma, a significant increase in myeloid dendritic cell (mDC) and plasmacytoid dendritic cell (pDC) density was observed that coincided with increased expression of their respective chemotactic factors, macrophage inflammatory protein-3 alpha (MIP3α), and chemerin in the same regions [76]. The gene discussed is CCL20; the disease is esophageal adenocarcinoma.
