Progressive loss of BDNF in a mouse model of Huntington's disease and rescue by BDNF delivery

Here we show that a reduction in cortical BDNF messenger level correlates with the progression of the disease in a mouse model of HD. In particular, we show that the progressive loss of mRNAs transcribed from BDNF exon II, III and IV follows a different pattern that may reflect different upstream mechanisms impaired by mutation in huntingtin. On this basis, we also discuss the possibility that delivery of BDNF may represent an useful strategy for Huntington's disease treatment.
