New frontiers in optogenetics

Developed in the early 2000s, optogenetic is a technique that allow scientists to use light to turn on and off neuronal cells by activating and deactivating certain proteins.

Oriimages.jpegginally, the proteins controlled this way were heavily engineered, inserted in the cells and just used as switch, so they did not give information about the function of this molecules as their original function was most of the time compromised.

Now, a new study published in Science expand this technique to the study of the native function of a wide range of proteins, unveiling how their roles differ according to where in the cells the proteins are working.
