Characterization of development of mHtt aggregates in the N171-82Q mouse model. (A) EM48-positive aggregates in N171-82Q mouse model. The black arrow points to the intranuclear inclusion. Magnification: 100×, scale bar = 10 μm. Magnification: 300×, scale bar = 5 μm. Appearance of EM48 positive aggregates in N171-82Q mice was analyzed in six points:10, 12, 14, 16, 19 and more than 19 weeks (between 20 to 30 weeks). (B) Development of huntingtin aggregates in striatum. The number of EM48 positive cells, intranuclear aggregates, and size of intranuclear inclusions increased in an age-dependent manner. (C) Formation of EM48-labelled aggregates in the neocortex. The number of intranuclear aggregates also increased in the neocortex in an age-dependent manner. (D) The number of intranuclear aggregates enhanced in the piriform cortex in an age-dependent manner. The values are expressed as means ± SEM. N = 3–5 animals per group.
