Huntington pathophysiology
WebObjective To define the role played by microglia in different stages of Huntington disease (HD), we used the TSPO radioligand [11C]-ER176 and PET to evaluate microglial activation in relation to neurodegeneration and in relation to the clinical features seen at premanifest and manifest stages of the disease. Methods This is a cross-sectional study in which 18 … WebIn this video, we explore Huntington’s disease: the pathogenesis, the signs and symptoms, and the mechanism as it relates to the basal nuclei in great detail...
