In a surprising new finding, neuroscientists have shown that human neurons have a much lower density of ion channels than expected, compared to the neurons of other mammals. Ion channels produce ...

Tetrameric cation channels are the largest and best characterized group of ion channels. For this type of ion channel, the ion pathway lies in a pore domain consisting of two transmembrane helices ...

Scientists have revealed the secret to the structural integrity of tiny particles that transport cargo from cell to cell through blood vessels and bodily fluids: special proteins that keep their ...

Cells send electrical impulses throughout the body, but electrophysiologists struggled to tune into these signals until the patch clamp technique was developed. Although biophysicist Bernard Katz from ...
