摘要：
The formation of aggregates of polyglutamine (polyQ) sequences is initiated by nucleated growth polymerization. New results show that over a short repeat length range from Q26 to Q23 the size of the nucleus changes from monomeric to dimeric to tetrameric, suggesting aggregation nucleus size has a role in pathogenicity.
