Mechanistic insights into the role of pyroptosis in rheumatoid arthritis

Curr Res Transl Med. 2020 Nov;68(4):151-158. doi: 10.1016/j.retram.2020.07.003. Epub 2020 Aug 20.

Abstract

Cell death is ascribed as an essential biological process that is fundamental for the development of an organism along with its survival. The procedure comprises of apoptosis and pyroptosis. Pyroptosis is a programmed procedure for cell death which is inflammatory in nature and this pathway gets activated via human caspase-4, human caspase-11 and human caspase-5. The activation of this process leads to release of pro-inflammatory mediators including cytokines, alarmins, IL-18 and IL-1β. The pro-inflammatory mediators released via interaction of intracellular kinases direct the development of Rheumatoid arthritis. Rheumatoid arthritis is characterized as disorder/disease that is auto-immune and chronic in nature. It involves erosions in marginal bone along with articular cartilage which is responsible for joint destruction. The cytokine along with its complex network is responsible for inflammation. The process of pyroptosis is linked with the destruction of plasma membrane, that releases these mediators and excessive release of these mediators is linked with rheumatoid arthritis.
