Autism Spectrum Disorder (ASD) is a series of complex neurodevelopmental disorders, which can affect children's social, behavioral and communication abilities. A member of the Sirtuins family of NAD + dependent deacetylases called SIRT2 could regulate the inflammation progress during stress, but the relevant mechanism has not been clearly defined. In the present study, the ASD model of wild type and SIRT2 knock out mice was established to evaluate the impact on the homeostasis of neurons in the hippocampus using western blotting, immunofluorescence and Nissl staining. The results showed that the amplification of neuronal richness was significantly decreased and neuroinflammation increased in the hippocampus following ASD due to autophagy, caused by enhancing the acetylation of FoxO1 using SIRT2 gene deletion and indicating this should be the target for ASD or other psychological stress treatment.
自闭症谱系障碍(ASD)是一系列复杂的神经发育障碍,可影响儿童的社交、行为和沟通能力。Sirtuins 家族的一种 NAD+依赖性去乙酰化酶 SIRT2 可以调节应激过程中的炎症进展,但相关机制尚未明确。本研究通过 Western blot、免疫荧光和尼氏染色,建立野生型和 SIRT2 敲除小鼠的 ASD 模型,评估其对海马神经元内稳态的影响。结果表明,由于自噬作用,ASD 导致海马神经元丰富度显著降低,神经炎症增加,这是通过 SIRT2 基因缺失增强 FoxO1 的乙酰化作用引起的,这表明 SIRT2 可能是 ASD 或其他心理应激治疗的靶点。
