Taurine deficiency associated with dilated cardiomyopathy and aging

Area of Science:

• Cardiology
• Nutritional Science
• Gerontology

Background:

• Taurine (2-aminoethanesulfonic acid) is abundant in mammalian heart tissue, maintained by the taurine transporter (TauT; Slc6a6).
• Taurine regulates cardiac ion dynamics, calcium handling, and acts as an antioxidant.
• Species with low taurine synthesis capacity are prone to deficiency-related disorders.

Purpose of the Study:

• To review the role of taurine deficiency in cardiomyopathy development.
• To explore the connection between taurine and age-related diseases.
• To summarize findings on taurine's impact on lifespan and healthspan.

Main Methods:

• Literature review of studies on taurine deficiency, cardiomyopathy, and aging.
• Analysis of research on taurine's physiological roles in the heart.
• Examination of studies investigating taurine levels in relation to lifespan and healthspan across species.

Main Results:

• Dietary taurine deficiency can cause dilated cardiomyopathy and blindness in susceptible species.
• Genetic mutations in the taurine transporter are linked to human dilated cardiomyopathy.
• Taurine levels decline with age and are associated with lifespan and healthspan in model organisms.

Conclusions:

• Taurine plays a critical role in maintaining cardiac function and potentially influences aging processes.
• Further research is needed to clarify the link between dietary taurine and human cardiomyopathy.
• Taurine deficiency may represent a modifiable factor in age-related diseases and longevity.
