toxicity in neurodegenerative disease--ALS and beyond
(this article discusses ALS in depth, though there is a short section on Parkinson's.)
" Selective degeneration and death of one or more classes of neurons is the defining feature of human neurodegenerative disease. Although traditionally viewed as diseases mainly affecting the most vulnerable neurons, in most instances of inherited disease the causative genes are widely—usually ubiquitously—expressed...We review here the evidence that it is the convergence of damage developed within multiple cell types, including within neighboring nonneuronal supporting cells, which is crucial to neuronal dysfunction. Damage to a specific set of key partner cells as well as to vulnerable neurons may account for the selective susceptibility of neuronal subtypes in many human neurodegenerative diseases,"... http://jcb.rupress.org/cgi/content/full/jcb.200908164v1 or the pdf version (which displays illustrations/charts, etc much better) though I am unsure if the following is accessible: http://jcb.rupress.org/cgi/reprint/jcb.200908164v1 |
