Exercise against nonalcoholic fatty liver disease: Possible role and mechanism of lipophagy.

Nonalcoholic fatty liver disease (NAFLD) is one of the most common causes of chronic liver disease worldwide. NAFLD is prevalent in about 30% of people worldwide. The lack of physical activity is considered as one of the risks for NAFLD, and approximately one-third of NAFLD patients hardly engage in physical activity.

Moderate intensity treadmill exercise alters food preference via dopaminergic plasticity of ventral tegmental area-nucleus accumbens in obese mice.

Obesity has been associated with the excessive intake of palatable food as well as physical inactivity. To investigate the neurobiological mechanism underlying the exercised-induced prevention and treatment of obesity, the present study examined the effect of treadmill exercise on the preference for palatable food in mice. Levels of tyrosine hydroxylase (TH) in the ventral tegmental area-nucleus accumbens system were also analysed, as well as levels of dopamine, dopamine transporter, and D2 receptors in the nucleus accumbens.
