abstract = {Ion channels are integral membrane proteins that upon
stimulation modulate the flow of ions across the cell or
organelle membrane. The resulting electrical signals are
involved in biological functions such as electrochemical
transmission and information processing in neurons.
Channelrhodopsins (ChRs) appear to be unusual channels. They
belong to the large family of microbial rhodopsins,
seven-helical transmembrane proteins containing retinal as
chromophore. Photon absorption initiates retinal
isomerization resulting in a photocycle, with different
spectroscopically distinguishable intermediates, thereby
controlling the opening and closing of the channel. In 2003,
it was demonstrated that light-induced currents by
heterologously expressed ChR2 can be used to change a
host’s membrane potential. The concept was further applied
to precisely control muscle and neural activity by using
light-induced depolarization to trigger an action potential
in neurons expressing ChR2. This optogenetic approach with
ChR2 and other ChRs has been widely used for remote control
of neural cells in culture and in living animals with high
spatiotemporal resolution. It is also used in biomedical
studies aimed to cure severe diseases.},
