Unlocking the role of Galectin-3: Implications for sleep disorders and health.

Galectin-3 is a member of the lectin family, and is an intriguing protein that is found in diverse tissues across the body. It is known for its multifaceted involvement in various physiological functions, including tissue repair, immune function and neuroinflammation in the central nervous system. It also serves as a paracrine signal, promoting the growth of certain cells and contributing to fibrosis, while higher levels of Galectin-3 in the bloodstream correlate with an increased risk of mortality and cardiovascular disease-related outcomes in the general population. Recent scientific studies have identified a potential link between Galectin-3 and sleep disorders. However, the precise mechanisms through which galectin-3 influences sleep disorders remain an active area of investigation. Although initial studies suggest a potential association between Galectin-3 and sleep disruptions, including conditions, such as insomnia, insufficient sleep time, and obstructive sleep apnea, further research is required to establish a more definitive relationship. This review explores recent findings regarding the potential connection between Galectin-3 and sleep patterns, and offers insights into the complex interplay between this protein and sleep. These discoveries present promising prospects for the development of innovative therapeutic approaches aimed at sleep disorder management, using Galectin-3 as a potential target for interventions or as a biomarker for sleep health.
