The role of TRPV ion channels in adipocyte differentiation: What is the evidence?

Obesity is a complex disorder, and the incidence of obesity continues to rise at an alarming rate worldwide. In particular, the growing incidence of overweight and obesity in children is a major health concern. However, the underlying mechanisms of obesity remain unclear and the efficacy of several approaches for weight loss is limited. As an important calcium‐permeable temperature‐sensitive cation channel, transient receptor potential vanilloid (TRPV) ion channels directly participate in thermo‐, mechano‐, and chemosensory responses. Modulation of TRPV ion channel activity can alter the physiological function of the ion channel, leading to neurodegenerative diseases, chronic pain, cancer, and skin disorders. In recent years, increasing studies have demonstrated that TRPV ion channels are abundantly expressed in metabolic organs, including the liver, adipose tissue, skeletal muscle, pancreas, and central nervous system, which has been implicated in various metabolic diseases, including obesity and diabetes mellitus. In addition, as an important process for the pathophysiology of adipocyte metabolism, adipocyte differentiation plays a critical role in obesity. In this review, we focus on the role of TRPV ion channels in adipocyte differentiation to broaden the ideas for prevention and control strategies for obesity. Significance statement: As an important calcium‐permeable temperature‐sensitive cation channel, transient receptor potential vanilloid (TRPV) ion channels directly have been implicated in various metabolic diseases. TRPV ion channels are involved in the maturation, differentiation, and thermogenesis of adipocytes. In this review, we provided an overview of the different effects of TRPV ion channels on adipocyte differentiation and central adiposity, which maybe potential therapeutic targets for managing obesity and related metabolic disorders.
