DCX and Huntington disease: Interestingly and similar to the post-mortem analysis in humans, we observed an increased number of DCX+ neuroblasts in the striatum adjacent to the SVZ in transgenic mouse and rat models of Huntington's disease (HD) suggesting that the damaged striatum may attract to some extent immature neuroblasts from the adjacent SVZ (Kohl et al., 2010; Kandasamy et al., 2015).
