In studying how neurotransmitters travel between cells, Cornell researchers have discovered that an electrical current thought to be present during that process does not, in fact, exist. The ...

Certain cells, commonly called excitable cells, are unique because of their ability to generate electrical signals. Although several types of excitable cells exist — including neurons, muscle cells, ...

Numerous recent crystal and cryo-EM structures have greatly advanced understanding of the functional mechanisms of neurotransmitter-gated ion channels. This Review discusses the structural basis of ...

Ion channels are transmembrane proteins specifically involved with the transport of inorganic ions like Na+, K+, Ca2+, or Cl-. Ion channels are “gated”, i.e. they open in response to a specific ...
