#Epilepsy Switch Discovered Approximately five percent of people suffers an epileptic attack, during which the nerve cells get out of their usual rhythm and fire in a very rapid frequency, over the course of their lives.
Often, a seizure disorder develops after a delay following transient brain damage-for example due to injury or inflammation.
Scientists at the University of Bonn and the Hebrew University of Jerusalem (Israel) have decoded a central signal cascade associated with epileptic seizures.
If the researchers blocked a central switch in epileptic mice, the frequency and severity of the seizures decreased.
it was possible to observe the processes prior to the occurrence of epileptic seizures in living animals."
"It has also been known for a long time that following transient severe brain injury and prior to an initial spontaneous epileptic seizure, the concentration of free zinc ions increases in the hippocampus.
If the number of zinc ions increases following transient severe brain damage, these ions dock in greater numbers onto a switch, the so-called metal-regulatory transcription factor 1 (MTF1.
This leads to a large increase in the amount of a special calcium ion channel in the nerve cells and overall, this significantly boosts the risk of epileptic seizures.
The scientists demonstrated the fact that the transcription factor MTF1 plays a central role in this connection using an experiment on mice suffering from epilepsy."
we inhibited MTF1 in the epileptic mice and as a result, the seizures in the animals were much rarer
This makes it possible to examine the processes which take place during the development of epilepsy in a living animal."
"If the fluorescence molecules glow, this indicates that the mouse is developing chronic epileptic seizures, "says the molecular biologist Prof.

The cells also react to TGF-beta by changing their shapes and secreting proteins that alter neuronal activity.
The researchers believe this CD4 paralysis mechanism could play a role in preventing autoimmunity, a hypothesis they supported by testing immunotherapy in a multiple sclerosis model.
