Interleukin-32 (IL-32) is a pro-inflammatory cytokine that was first characterized in2005.it was named IL-32 due to its potent pro-inflammatory effects. IL-32 does not contain a typical hydrophobic signal peptide at the N terminus for secretion, but IL-32 was detected in the supernatant of stimulated cells, how IL-32 is secreted is still not fully understood. Also, it is still unclear through which cell surface receptor IL-32 mediates its function. IL-32 may also have an important function as an intracellular protein55. IL-32, via interactions with some other molecules, has been reported to be involved in various intracellular signaling. The focus of the present review is on the properties of this cytokine in liver diseases. Understanding the involvement of IL-32 in the pathogenesis of liver diseases may assist in identifying novel therapeutic strategies to mitigate or prevent liver diseases.
