Optogenetic control of cellular forces and mechanotransduction
Contractile forces are the end effectors of cell migration, division, morphogenesis, wound healing and cancer invasion. Here we report optogenetic tools to upregulate and downregulate such forces with high spatiotemporal accuracy. The technology relies on controlling the subcellular activation of RhoA using the CRY2/CIBN light-gated dimerizer system. We fused the catalytic domain (DHPH domain) ...
متن کاملOptogenetic control of kinetochore function
Kinetochores act as hubs for multiple activities during cell division, including microtubule interactions and spindle checkpoint signaling. Each kinetochore can act autonomously, and activities change rapidly as proteins are recruited to, or removed from, kinetochores. Understanding this dynamic system requires tools that can manipulate kinetochores on biologically relevant temporal and spatial...
متن کاملOptogenetic control of epileptiform activity.
The optogenetic approach to gain control over neuronal excitability both in vitro and in vivo has emerged as a fascinating scientific tool to explore neuronal networks, but it also opens possibilities for developing novel treatment strategies for neurologic conditions. We have explored whether such an optogenetic approach using the light-driven halorhodopsin chloride pump from Natronomonas phar...
متن کاملOptogenetic control of cardiac function.
The cardiac pacemaker controls the rhythmicity of heart contractions and can be substituted by a battery-operated device as a last resort. We created a genetically encoded, optically controlled pacemaker by expressing halorhodopsin and channelrhodopsin in zebrafish cardiomyocytes. Using patterned illumination in a selective plane illumination microscope, we located the pacemaker and simulated t...
متن کاملOptogenetic control of ROS production
Reactive Oxygen Species (ROS) are known to cause oxidative damage to DNA, proteins and lipids. In addition, recent evidence suggests that ROS can also initiate signaling cascades that respond to stress and modify specific redox-sensitive moieties as a regulatory mechanism. This suggests that ROS are physiologically-relevant signaling molecules. However, these sensor/effector molecules are not u...
