Huntington's disease
Huntington's disease is a progressive and fatal hereditary disease that manifests itself in the brain. It is characterized by dyskinesia, dementia, and behavioral and psychological changes. To date, there is no cure, although scientists have a relatively good understanding of its molecular causes. The Huntington's gene of those affected contains up to 200 copies of a specific base triplet (group of three bases). This causes the cells to produce a defective protein, which primarily forms deposits in the striatum of the brain. This leads to degeneration of the neurons in the basal ganglia and the cortex.

CREB
A transcription factor in the cell nucleus that is activated by cAMP-dependent signaling pathways. CREB influences gene activity and can thus improve communication between two cells. This is a cellular basis for learning processes.

Neurodegeneration
Collective term for diseases in which nerve cells gradually lose their structure or function until they eventually die. In many cases, misfolded proteins are the trigger – such as certain forms of the proteins beta-amyloid and tau in the case of Alzheimer's disease. In other diseases, such as Parkinson's disease or Huntington's disease, proteins within the neurons are not broken down properly. As a result, toxic aggregates are deposited there, leading to the respective disease symptoms. While Huntington's disease is clearly genetic, in Parkinson's and Alzheimer's there appear to be certain gene variants that promote their development. None of these neurodegenerative diseases can be cured at present.
