HTT and Huntington disease: CBG via the nuclear receptor peroxisome proliferator-activated receptor-γ (PPARγ) alleviates motor symptoms, neuroinflammation and neurodegeneration in murine models of HD based on either striatal neurotoxicity (3-nitropropionic acid injection model) or transgenic expression of human mutant huntingtin exon 1 (R6/2 model) [12].
