New Discovery Reveals Sex-Specific Causes of Depression Triggered by Stress Hormones Dysfunction

Men are more likely to have a dysregulated HPA axis that is associated with depressive symptoms, while women have higher levels of binding proteins for stress hormones that may prevent dysregulation of the HPA axis. The findings shed new light on how stress hormones impact dopamine transmission and how this impacts depression on a sex-specific basis.

How Huntington’s Disease Affects Different Neurons

Researchers have identified how two different populations of neurons in the striatum are affected differently in Huntington's disease. The neurodegeneration of one of these populations leads to motor defects while damage to the other population located in striosomes may account for mood disorders associated with the early stages of Huntington's.
