The Nobel Prize @NobelPrize - This year’s medicine laureate Karl Deisseroth transformed the protein channelrhodopsin into a light-controlled switch for nerve cells. Deisseroth introduced the gene for channelrhodopsin into nerve cells from rats. By illuminating the cells with blue light, he was able to trigger a nerve signal. He published this breakthrough in 2005. Two years later, he made this light-controlled switch for nerve cells work in the brains of living mice. #NobelPrize https://x.com/NobelPrize/status/2107041353662103591
The Nobel Prize @NobelPrize - Peter Hegemann and Georg Nagel – awarded the 2026 medicine prize – discovered a remarkable protein, channelrhodopsin, in a single-celled alga. Hegemann wondered how Chlamydomonas, a single-celled alga, is able to swim towards a light source. In the early 2000s, he and Georg Nagel discovered channelrhodopsin, an algal protein with unique properties, found on the surface of the cell. When it is illuminated by blue light, a channel opens through the protein. Charged ions then flow into the cell, creating an electrical impulse. They found that regardless of which cell they put the protein in, those cells became light sensitive. #NobelPrize https://x.com/NobelPrize/status/2107041279188009136
