Lipid Metabolic Disorders in Neurodegenerative Diseases - Role of Androgen Receptor

The challenge of managing neurodegenerative disorders is a worldwide concern, especially in the aging population. Neurodegenerative diseases are a varied group of disorders that are characterized by progressive degeneration of the structure and function of the nerve cells. Neurodegenerative diseases are increasing at an alarming rate, and hence there is an urgent need for an in-depth analysis of various metabolic malfunctions that alter the proper functioning of a cell. Lipid metabolism is a process that involves the synthesis and simultaneous degradation of lipids and encompasses a balance that is essential to maintain the structural and functional ability of a cell. Androgen receptor (AR) plays a critical role in regulating cellular functions. Recent studies have expanded our knowledge regarding direct or indirect interactions that occur among mitochondria, peroxisome, and androgen receptors, which play a crucial role in lipid homeostasis. Unusual levels of lipids and cholesterol due to receptor excitation or inhibition are associated with multiple diseases and have been a cause of concern. The androgen receptor, along with other receptors and proteins, forms an important metabolic cascade that, if altered, may cause the accumulation of lipids and result in neurodegenerative disorders. In this review, we underscore the role of the androgen receptor in regulating lipid and cholesterol levels during neurodegenerative disorders (Alzheimers, Parkinson's, multiple sclerosis, and Huntington's disease).
