Huntington’s disease (HD) is a prototypical neurodegenerative disease, preferentially disrupting the neurons of the striatum and cortex. Progressive motor dysfunctions, psychiatric disturbances, behavioral impairments, and cognitive decline are the clinical symptoms of HD progression. The disease occurs due to expanded CAG repeats in exon 1 of huntingtin protein (mHtt), causing its aggregation. Multiple cellular and molecular pathways are involved in HD pathology. Mitochondria, as vital organelles have an important role in most neurodegenerative diseases like HD. Over the years, the role of mitochondria in neurons has highly diverged; they not only contribute as a cell power source, but also as dynamic organelles that fragment and then fuse to attain a maximal bioenergetics performance, regulating intracellular calcium homeostasis, reactive oxygen species (ROS) generation, antioxidant activity and involved …
