WebNeurofibrillary tangles (NT) are pathological insoluble aggregates of hyperphosphorylated tau proteins, which are microtubule-associated proteins, observed within the neurons of … 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.
