Advances in Research of Cell Pyroptosis, Ulcerative Colitis and Regulation with Traditional Chinese Medicine / 中国实验方剂学杂志

ABSTRACT

Pyroptosis，which is different from cell necrosis， apoptosis and autophagy，is a new type of programmed cell death. It is characterized by the swelling of cells until the cell membrane rupture， resulting in the release of cell contents and the activation of a strong inflammatory response. Pyroptosis signaling pathway is divided into the classical pathway dependent on Caspase-1 and the non-classical pathway dependent on Caspase-4， 5 and 11. In classical pathway， activation Caspase-1 depends on inflammasome， whereas in non-classical pathway， Caspase-4， 5， and 11 are activated directly. All of these result in the cleavage of gasdermin D（GSDMD） protein， the formation of membrane pores， the maturation and release of interleukin-1β（IL-1β） and IL-18， and the rupture of the cell membrane， and then leads to pyroptosis. Ulcerative colitis （UC） is a common disease of the digestive system. The UC course is long， easy to relapse， and difficult to cure. The pathogenesis of UC is not completely clear. In recent years， it has been found that pyroptosis plays an important role in the development of UC. Traditional Chinese medicine（TCM） has a long history of preventing and treating UC， with significant clinical effects. It is found that the mechanism of TCM in the prevention and treatment of UC is closely correlated with inflammasome， IL-1β and IL-18. The mechanism of TCM in preventing and treating UC is correlated with cell pyroptosis. Therefore， this paper reviews the relationship between cell pyroptosis and UC and the regulatory effect of TCM.
