Aquaporins in Immune System.

ABSTRACT

Recent studies have shown that at least six aquaporins (AQPs), including AQP1, AQP3, AQP4, AQP5, AQP7, and AQP9, are expressed in immune system. These AQPs distribute in lymphocytes, macrophages, dendritic cells, and neutrophils, and mediate water and glycerol transportation in these cells, which play important roles in innate and adaptive immune functions. Immune system plays important roles in body physiological functions and health. Therefore, understanding the association between AQPs and immune system may provide approaches to prevent and treat related diseases. Here we will discuss the expression and physiological functions of AQPs in immune system and summarize recent researches on AQPs in immune diseases.
