Molecular Ion Channel Physiology

Nerve cells are close to the threshold that makes them fire rapid nervous impulses.

An altered threshold can cause epilepsy or pain. We study a new mechanism by which different substances can restore the threshold by opening or closing of voltage-gated ion channels.

A drug from resin to combat epileptic seizures

New molecules, developed by researchers at Linköping University, have promising properties as possible drugs against epilepsy. A study published in the journal Epilepsia shows that several of the molecules have antiseizure effects.

New mechanism affecting nerve impulses discovered

Researchers at LiU have discovered a new mechanism by which substances can open a certain type of ion channel and in this way regulate nerve impulses. The discovery, published in the journal PNAS, may help in the development of future drugs.

Drug development – not only in industry

Neuroscientists obtain support from SciLifeLab when working to develop new drugs against epilepsy. The project is the first from Linköping University that has been accepted as a full program for the Drug Discovery and Development Platform (DDD).
