potential of an MT imaging agents, no PET ligand is currently available for in vivo imaging of MTs in the brain. We radiolabeled [11C]MPC-6827, a high affinity MTA, and demonstrated its specific binding in rat and mice brain using PET imaging. Our experiments show that [11C]MPC-6827 has specific binding to MT in brain, and it is the first MT-binding PET ligand.
微管(MTs)的异常与许多中枢神经系统疾病的发病机制有关。尽管MT成像剂具有潜力,但目前尚无PET配体可用于大脑中MT的体内成像。我们对[ 11 C] MPC-6827(高亲和力MTA)进行了放射性标记,并使用PET成像证明了其在大鼠和小鼠大脑中的特异性结合。我们的实验表明[ 11 C] MPC-6827与大脑中的MT具有特异性结合,并且是第一个与MT结合的PET配体。
