Abstract: BACKGROUND: Unlike non-inflammatory cell apoptosis, pyroptosis is a form of inflammatory cell death, characterized by membrane integrity disruption and release of pro-inflammatory intracellular substances. Thus, it is associated with various diseases. The sirtuin family is a group of histone deacetylases dependent on nicotinamide adenine dinucleotide. In addition to deacetylation, it also possesses other enzymatic activities such as desuccinylation, demalonylation, adenosine diphosphate-ribosylation and playing crucial roles in the regulation of pyroptosis. 
OBJECTIVE: To review the role of the sirtuins in pyroptosis.
METHODS: The first author conducted a search on PubMed, Web of Science, CNKI, and WanFang Data from inception to March 2024, using the Chinese and English search terms “Sirtuins, Sirtuin1, Sirtuin2, Sirtuin3, Sirtuin4, Sirtuin5, Sirtuin6, Sirtuin7, pyroptosis”, resulting in the inclusion of 71 articles.
RESULTS AND CONCLUSION: (1) The sirtuin family all participates in the regulation of pyroptosis. (2) Overexpression of sirtuin1 and sirtuin4 can inhibit pyroptosis through various pathways, thus alleviating the damage caused by pyroptosis to the organism. (3) In addition to affecting the classical pathway of pyroptosis, sirtuin3 can also inhibit pyroptosis by enhancing mitochondrial reactive oxygen species scavenging capacity and mitosis. (4) Sirtuin5 is involved in the regulation of intracellular metabolism and energy balance, including energy intake, storage, and consumption. (5) Sirtuin6 can influence pyroptosis through various pathways and also affect macrophage M1 polarization, generation of reactive oxygen species, and cleavage of pyroptosis-related factor sclerotin D to inhibit pyroptosis. (6) Overexpression of sirtuin7 can suppress pyroptosis. (7) Sirtuin2, unlike other family members, can restrain pyroptosis only after knockdown, but there are fewer reports, requiring more in-depth and comprehensive research. 

Key words: sirtuins, pyroptosis, deacetylation, oxidative stress, inflammation
