Synthetic biological approaches to optogenetically control cell signaling.

Precise spatial and temporal control of cellular processes is in life sciences a highly sought-after capability. In the recent years, this goal has become progressively achievable through the field of optogenetics, which utilizes light as a non-invasive means to control genetically encoded light-responsive proteins. The latest optogenetic systems, such as those for control of subcellular localization or cellular decision-making and tissue morphogenesis provide us with insights to gain a deeper understanding of the cellular inner workings. Besides, they hold a potential for further development into biomedical applications, from in vitro optogenetics-assisted drug candidate screenings to light-controlled gene therapy and tissue engineering.
