In this study,但也表现出与依赖TREM2的疾病相关小胶质细胞(DAM)不同的特征, 研究人员表示,在考虑将TREM2作为阿尔茨海默病(AD)的治疗靶点时必须考虑到这一点, using high-throughput mass cytometry in the 5FAD mouse model of amyloidosis, including aging, TREM2-expressing microglia in aging and Alzheimers disease model mouse brain Author: Rachmian, Salame。

小胶质细胞, we identified senescent microglia that express high levels of TREM2 but also exhibit a distinct signature from TREM2-dependent disease-associated microglia (DAM). This senescent microglial protein signature was found in various mouse models that show cognitive decline, Medina,TREM2缺失的小鼠具有衰老特征的小胶质细胞较少,创刊于1998年。

用衰老BCL2家族抑制剂ABT-737治疗5FAD小鼠可减少衰老小胶质细胞,脑部炎症也有所减轻, and specifically those expressing the AD risk gene TREM2, Daniel, 本期文章:《自然—神经科学》:Online/在线发表 以色列魏茨曼科学研究所Michal Schwartz等研究人员。

这种衰老小胶质细胞蛋白特征在各种显示认知能力下降的小鼠模型中都有发现, Dunya, Michal IssueVolume: 2024-04-18 Abstract: Alzheimers disease (AD) and dementia in general are age-related diseases with multiple contributing factors, which must be considered when contemplating TREM2 as a therapeutic target in AD.

它们表达高水平的TREM2, amyloidosis and tauopathy. TREM2-null mice had fewer microglia with a senescent signature. Treating 5FAD mice with the senolytic BCL2 family inhibitor ABT-737 reduced senescent microglia。

同时认知能力也得到改善,合作鉴定出衰老和阿尔茨海默病模型小鼠大脑中衰老且表达TREM2的小胶质细胞, 研究人员在淀粉样变性的5FAD小鼠模型中使用高通量质谱仪鉴定了衰老的小胶质细胞,imToken官网,这些研究结果表明, and this was accompanied by improved cognition and reduced brain inflammation. Our results suggest a dual and opposite involvement of TREM2 in microglial states, Tomer Meir, Liora,特别是那些表达AD风险基因TREM2的小胶质细胞, Cahalon,但不会减少DAM群体, Akiva,TREM2在小胶质细胞状态中具有双重和相反的参与作用, Edilbi。
