Abstract:
The main histopathological feature of Huntington's disease (HD) is the presence of protein aggregates that are gathered into inclusion bodies. So far the mechanisms that lead to inclusion formation as well as their role in the pathogenesis of HD are not totally understood. However, it is well established that inclusion bodies contain components of the ubiquitin-proteasome system. Accordingly, it has been postulated that impairment of this machinery can be one of the causes of this disorder. In this review, the authors summarize the state of current knowledge about this hypothesis.

The Proteasome
In this pathway, the target proteins are first tagged with small proteins called ubiquitin. This involves participation of a series of enzymes including— E1 (ubiquitin-activating enzyme), E2 (ubiquitin-conjugating enzyme), and E3 (ubiquitin...
