WebApr 19, 2024 · In the brains of people with Alzheimer’s, tau proteins start amassing in neurofibrillary tangles, obstructing the cellular highways and getting in the way of synaptic communication between neurons. Eventually, they can even contribute to the death of brain cells. Like the presence of amyloid plaques, tau tangles are hallmarks of Alzheimer’s. 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. dandridge tn to memphis tnWebProfessor Kenneth Kosik discusses neurofibrillary tangles, which form inside a cell and are made up of a protein called tau.
