更关键的是,炎症与Aβ斑块、tau纤维缠结间的相互作用机制始终存在"鸡生蛋还是蛋生鸡"的争论,这直接影响了靶向干预策略的开发。 华盛顿大学的研究团队通过创新性应用第二代TSPO配体[11C]ER176,首次实现对早期起病AD(EOAD)患者全TSPO基因型(HAB/MAB/LAB)的炎症成像。该示踪剂突破性地将LAB人群的非置换结合潜能(BP...
Although test-retest reliability is critical to estimate a necessary sample size, this has not been established for 11C-ER176 PET. Because of the low specific and total binding, test-retest variability may be poor in LABs. In addition, one study indicated possible diurnal changes of TSPO ...

[11C]ER176 is a PET radioligand that images neuroinflammation via the 18-kDa translocator protein (TSPO), which is upregulated in activated microglia and has previously been a PET target in Alzheimer's disease research. Currently, the gold-standard method for quantifying ER176 PET is kinetic ...
[11C]ER176, specifically binding to TSPO, has been developed as the third generation of radioligand for PET imaging of TSPO, which showed the potential in better quantifying neuroinflammation than its predecessors. In the current study, we developed an automated radiosynthesis with an imp...

Because of its excellent ratio of specific to nondisplaceable uptake, the radioligand 11C-ER176 can successfully image 18-kDa translocator protein (TSPO), a biomarker of inflammation, in the human brain and accurately quantify target density in homozygous low-affinity binders. Our laboratory sought ...
Furthermore, [11C]ER176 has shown favorable kinetics with 4 to 9-fold increase in binding potential compared to [11C]PBR28 (Zanotti-Fregonar 2019). In this study we investigated the use of semi-automated solid phase extraction (SPE) to replace rotary evaporation (Ikawa 2017) for the ...
