ABSTRACT
Polyglutamine disorders are neurodegenerative diseases that share a CAG repeat expansion in the coding region, resulting in aggregated proteins that can be only degraded through aggrephagy. We measured the expression of autophagy genes in peripheral blood mononuclear cells of 20 patients with Huntington's disease (HD), 20 with spinocerebellar ataxia type 2 (SCA2), and 20 healthy individuals. HD patients showed increased expression of MAP1LC3B (+ 43%; p = 0.048), SQSTM1 (+ 49%; p = 0.002), and WDFY3 (+ 89%; p < 0.001). SCA2 patients had increased expression of WDFY3 (+ 69%; p < 0.001). We show that peripheral markers of autophagy are elevated in polyQ diseases, and this is particularly evident in HD.
