Sirtuin 2 is a member of the sirtuin family nicotinamide adenine dinucleotide(NAD~+)-dependent deacetylases, known for its regulatory role in different processes, including inflammation. In this context, sirtuin 2 has been involved in the modulation of key inflammatory signaling pathways and transcription factors by deacetylating specific targets, such as nuclear factor κB and nucleotide-binding oligomerization domain-leucine-rich-repeat and pyrin domain-containing protein 3(NLRP3). However, whether sirtuin 2-mediated pathways induce a pro-or an anti-inflammatory response remains controversial. Sirtuin 2 has been implicated in promoting inflammation in conditions such as asthma and neurodegenerative diseases, suggesting that its inhibition in these conditions could be a potential therapeutic strategy. Conversely, arthritis and type 2 diabetes mellitus studies suggest that sirtuin 2 is essential at the peripheral level and, thus, its inhibition in these pathologies would not be recommended. Overall, the precise role of sirtuin 2 in inflammation appears to be context-dependent, and further investigation is needed to determine the specific molecular mechanisms and downstream targets through which sirtuin 2 influences inflammatory processes in various tissues and pathological conditions. The present review explores the involvement of sirtuin 2 in the inflammation associated with different pathologies to elucidate whether its pharmacological modulation could serve as an effective strategy for treating this prevalent symptom across various diseases.

Hyperlipidemia is associated with many diseases and considered the main contributing factor in the development of metabolic syndrome. The traditional Mongolian medicine Dracocephalum moldavica L. (D. moldavica) is commonly consumed as a tea (non-Camellia tea) for the prevention and treatment of coronary heart disease， hypertension， atherosclerosis， and other diseases. Here， we attempted to investigate the hypolipidemic activity and mechanisms underlying the active components of D. moldavica. First， the mechanism underlying the lipid accumulation-reducing effects of the D. moldavica ethanol extract was determined using in vitro experiments， and four polar fractions were screened for activity. Then， the effect of the ethyl acetate fraction of D. moldavica (EAD) on lowering blood lipid was confirmed in vivo. The combination of network pharmacological and serum pharmacochemistry analyses showed that apigenin， luteolin， and naringenin of EAD existed in prototype form in the drug-containing serum of rats. We also determined the content of the three active ingredients in EAD. Finally， in vitro experiments showed that apigenin， luteolin， and naringenin improved oleic acid-induced lipid accumulation in HepG2 cells by regulating the PPAR signaling pathway (PPARα， CPT1， and FABP3). Our findings provide mechanistic insights and application prospects for the prevention and treatment of hypolipidemia using D. moldavica.
