The role of P2X7 receptor in infection and metabolism: Based on inflammation and immunity.

• The P2X7R is mainly expressed in immune cells, particularly monocytes. • The P2X7R can be activated by physiological or non-physiological agonists. • The function of the P2X7R correlates with the duration and intensity of the stimulus. • The P2X7R is a switch for inflammation and immunity. • The P2X7R plays an important role in infection and metabolism. The P2X7 receptor (P2X7R) is a ligand-gated receptor belonging to the P2 receptor family. It is distributed in various tissues of the human body and is involved in regulating the physiological functions of tissues and cells to affect the occurrence and development of diseases. Unlike all other P2 receptors, the P2X7 receptor is mainly expressed in immune cells and can be activated not only by extracellular nucleotides but also by non-nucleotide substances which act as positive allosteric modulators. In this review, we comprehensively describe the role of the P2X7 receptor in infection and metabolism based on its role as an important regulator of inflammation and immunity, and briefly introduce the structure and general function of the P2X7 receptor. These provide a clear knowledge framework for the study of the P2X7 receptor in human health. Targeting the P2X7 receptor may be an effective method for the treatment of inflammatory and immune diseases. And its role in microbial infection and metabolism may be the main direction for in-depth research on the P2X7 receptor in the future. [ABSTRACT FROM AUTHOR]
