Huntington’s Gene Enhances Early Brain Growth and Intelligence

A study reveals that the genetic mutation causing Huntington’s disease (HD) enhances brain development and intelligence in early life, but leads to degeneration in adulthood. Children with the HD gene exhibit larger brains and higher IQs than those without the mutation.

Key Biochemical Trigger of Huntington’s Disease Progression Identified

Researchers have identified a crucial biochemical mechanism that could allow Huntington’s disease to be studied before symptoms appear, offering hope for early intervention. The team found that disrupted dopamine regulation in specific neurons, related to TrkB neurotrophin receptor signaling, may trigger Huntington’s onset. By targeting an enzyme called GSTO2, researchers prevented motor symptoms in a mouse model, suggesting this protein's role in the disease's progression.

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.
