Beyond The Brain: A Study Of Α-Synuclein's Role In Bone And Adipose Tissue, Carolina A. Figueroa

Electronic Theses and Dissertations

α-Synuclein is a polypeptide encoded by the Snca gene, highly expressed in neurons, but it is also found in bones and adipose tissue. Co-expression analysis showed that Snca regulates skeletal homeostasis, and its deletion reduced estrogen deficiency-induced bone loss and weight gain. It is a major component of Lewy bodies (LB) in Parkinson’s disease (PD), leading to progressive immobilization and a range of nonmotor symptoms, including osteopenia, body composition alterations and insulin resistance. This thesis aimed to determine α-Synuclein’s intrinsic role in bone and adipose homeostasis. We discussed the PD pathophysiology emphasizing aspects of bone health and metabolism. By using …
