... later reported (Altman, '62a; Koenig, et al., '62) that, as a consequence of brain trauma, glia cells become labeled in large numbers at sites of experimentally pro­ voked gliosis. This latter finding added support to the interpretation that the la­ beling reflects cell proliferation. The aim of thi ...

Channelrhodopsin



Channelrhodopsins are a subfamily of retinylidene proteins (rhodopsins) that function as light-gated ion channels. They serve as sensory photoreceptors in unicellular green algae, controlling phototaxis: movement in response to light. Expressed in cells of other organisms, they enable light to control electrical excitability, intracellular acidity, calcium influx, and other cellular processes. Channelrhodopsin-1 (ChR1) and Channelrhodopsin-2 (ChR2) from the model organism Chlamydomonas reinhardtii are the first discovered channelrhodopsins. Variants have been cloned from other algal species, and more are expected.
