Neurofibrillary tangles (NFT) is a pathological hallmark of Alzheimer’s disease (AD). NFT is composed of aggregated tau protein and is correlated to cognitive decline in dementia progression. NFT spreads in the brain in a prion-like manner, mediated by the interaction between tau and neuronal surface glycans. The long-term goal is to study the structural details of tau-glycan interaction and to discover drugs to disrupt this interaction for disease-modifying treatment of AD. In this proposal, we will study the tau-heparan sulfate interaction from at the molecular (aim 1), the cellular (aim 2), and organismal level and carry out drug discovery (aim 3).

神经原纤维缠结（NFT）是阿尔茨海默氏病的病理标志（AD）。 tau蛋白的综合蛋白与痴呆进展的认知下降相关。 以tau和神经元表面糖之间的相互作用介导的王子样 目标是研究tau-glycan互动的故事，并发现破坏这种互动的药物 对于疾病改良的AD治疗，我们将研究Tau​​-Heparan硫酸 在分子（AIM 1），细胞（AIM 2）和生物水平并进行药物发现（AIM 3）上。
