<p>The signaling mechanisms of nucleotides and nucleosides have been extensively studied over the past decades in various conditions affecting distinct organs and tissues. It is well-established that purinergic receptors are expressed in healthy tissues, with expression levels often increasing under pathological conditions. These receptors play crucial roles in numerous physiological and pathological processes, including inflammation, tissue repair, and cellular signaling. However, the purinergic context in the esophagus and its associated pathologies remains poorly understood, representing a significant gap in current knowledge. In this review, we compiled and analyzed the available data on the involvement of P2 purinergic receptors in esophageal diseases, such as gastroesophageal reflux disease and esophageal carcinoma. Specifically, we discuss the pharmacological modulation, functional characterization, and expression patterns of these receptors in various esophageal cell lines and immune tissue samples, under both healthy and pathological conditions. Understanding the mechanisms of action and signaling pathways involving P2 purinergic receptors in the esophagus can offer valuable insights into their biological roles and emphasize their potential as therapeutic targets for future clinical applications.</p>
