How do neurofibrillary tangles form
WebProfessor Kenneth Kosik discusses neurofibrillary tangles, which form inside a cell and are made up of a protein called tau. There is a strong relationship with plaques and amyloid deposition. The other hallmark of Alzheimer’s disease is the neurofibrillary tangle. That is made up of a different protein, a protein called tau (T-A-U, the ... WebNeurofibrillary tangles found in Alzheimer’s disease result from the hyperphosphorylation of tau. Phosphorylation of tau can occur at many sites, typically by the kinases GSK3, CDK5, and results in a decreased ability to bind microtubules.

They are … Neurofibrillary tangles are formed by hyperphosphorylation of a microtubule-associated protein known as tau, causing it to aggregate, or group, in an insoluble form. (These aggregations of hyperphosphorylated tau protein are also referred to as PHF, or "paired helical filaments"). The precise mechanism of tangle formation is not completely understood, and it is still controversial whether tangles are a primary causative factor in disease or play a more peripheral role.
