Context-dependent role of sirtuin 2 in inflammation

引用

neural Regeneration Research 2025年第3期20卷 682-694页

作者： noemíSola-Sevilla Maider Garmendia-Berges MCarmen Mera-Delgado Elena Puerta Department of Pharmaceutical Sciences Division of PharmacologySchool of Pharmacy and NutritionUniversity of NavarraPamplonaSpain navarra institute for health Research(IdiSnA) PamplonaSpain

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.
