Optogenetics: Rho GTPases Activated by Light in Living Macrophages.
Abstract:
Genetically encoded optogenetic tools are increasingly popular and useful for perturbing signaling pathways with high spatial and temporal resolution in living cells. Here, we show basic procedures employed to implement optogenetics of Rho GTPases in a macrophage cell line. Methods described here are generally applicable to other genetically encoded optogenetic tools utilizing the blue-green spectrum of light for activation, designed for specific proteins and enzymatic targets important for immune cell functions.
