WebAug 31, 2024 · How do neurofibrillary tangles interfere with cellular communication? Changes in brain chemistry make tau protein molecules come away from the microtubules and stick to each other instead. Eventually, the detached tau molecules form long filaments, or neurofibrillary tangles, that disrupt the brain cell’s ability to communicate with other … WebNeurofibrillary tangles are composed of highly phosphorylated forms of the microtubule-associated protein tau. Phosphorylated tau proteins accumulate early in neurones, even …
