2 Figure 1 A Model of Polyglutamine-Induced Neurodegeneration and Its Reversal (A) Expression of a mutant peptide with expanded polyglutamine (Q) tract leads to neuronal degeneration and eventual death. Note that both aggregated and solitary protein induce neuronal dysfunction that precedes death. (B) Turning off mutant protein expression gives the neuron enough of a reprieve to clear the mutant protein by the chaperone/ubiquitin-proteasome pathway (UPP) and subsequently recover at least some function.
