Molecular trigger for Huntington's disease found

...ors include abnormal reflexes such as an inhibited startle response to loud noise, which is also present in human HD patients. "In summary, our study establishes a specific role for p53 in HD," concluded Sawa and colleagues. "As p53 is a nuclear transcription factor that regulates various mitochondrial gene...

...ed transmission of visual signals, and an enhanced startle response to sudden noise. Electrophysiological studies of the mutant animals' brain and spinal neurons showed significant zinc-related abnormalities in transmission of signals at the connections, called synapses, among neurons.
