    well, as per my knowledge you have missed the work of secretases as Alpha and Gamma secretases cause a healthy breakdown of protein while beta cleavage is misdirected. But in the video, you said gamma-secretase cleavage cause disturbance that's not true. Please go through the latest articles and correct me if I am wrong. Thanks

    Hi, very good work, thank you.
    I have a question : what is the link between Tau misfloding and hyperphosphorylation of Tau ? Does Tau is hyperphosphorylated because it is misfloding ?
    If someone anserw to my question, I thank him in advance.
    Happy new year 2022!

    50% of patients with the plaques do not exhibit Alzheimers symptoms so I would rule that cause out. How does a prion develop? That is the question.

    I was wondering, why does the calcium influx cause apoptosis and not necrosis?

    • @veccio
      @veccio Місяць тому

      Because the Ca+ itself is considered an apoptosis signaller at a certain level, I think. pmc.ncbi.nlm.nih.gov/articles/PMC1569591/

    Is ALS a Prion Disease?

  • @ryanrohrbacker7431
    @ryanrohrbacker7431 Рік тому +1

    this is honestly not right at all in regards to pathophysiology and microphysiology of how plaques and tangles are caused . The basics are mentioned just not the intricacies on how everything comes together. for example tau proteins don't unfold , they’re hyper polarized through hyperphosphorylation from the amyloid beta plaques outside the neurons themselves causing clumps giving a weak cytoskeleton within the neuron. Then with the weak and half dead neurons they clump up and cause neurofibrillary tangles. Amyloid beta plaques are a whole other beast, they’re outside the neuron not within the neuron.

      Had exactly this doubt, I'm learning about prions and the diseases they cause. I think the PrP protein has nothing to do with tau and amyloid beta right?

      @@celinat8622 Other resources say it is double prion disease involving tau prions and amyloid prions, which is difficult to believe. I believe the researcher is Prusiner.
