Cholesterol restores cortico-striatal synaptic connectivity in Huntington's disease through BDNF-TrkB signalling, supporting a role for cholesterol pathways implicated by human genetic modifier studies.
It is shown that increasing cholesterol availability prevents synapse loss and restores cortico-striatal connectivity in HD models, establishing cholesterol as a critical regulator of cortico-striatal synaptic integrity in HD and supporting targeting cholesterol homeostasis as a therapeutic strategy to restore synaptic...
