Hormone linked to depression

摘要

A hormone released by fat cells that is associated with a reduced risk of type 2 diabetes could also protect against depression.rnBlood levels of the hormone adiponectin are positively correlated with insulin sensitivity. Xin-Yun Lu at the University of Texas at San Antonio and her colleagues manipulated levels of adiponectin in the blood and brains of mice, and assessed the animals' likelihood of exhibiting depression-like behaviours in response to stressors. The researchers found that mice with low blood levels of the hormone were more likely to show signs of depression than were control animals.
