  10. [ note : in neurodegeneration the main aggregates tend to form in other parts of the cell than the lysosome, but there is good evidence that this is a compensatory measure when neurons ' lysosomes stop working properly as a result of the more modest accumulation of lysosomal toxins, so if we fix the lysosome then the non - lysosomal aggregates should disappear naturally

    [附註：在神經性退化中，主要的堆積物往往在細胞的其他部分形成、而不是在溶酶體形成，但有很好的證據表明，這是一種補償措施：當神經原的溶酶體因溶酶體毒素積累到一定程度就停止工作，所以，如果我們修理了溶酶體，那麼非溶酶體的堆積物就會自然消失。
