Development and application of optogenetic tools / 生物工程学报

Dynamic variations of the cell microenvironment can affect cell differentiation, cell signaling pathways, individual growth, and disease. Optogenetics combines gene-encoded protein expression with optical controlling, and offers a novel, reversible, non-invasive and spatiotemporal-specific research tool to dynamically or reversibly regulate cell signaling pathways, subcellular localization and gene expression. This review summarizes the types of optogenetic components and the involved cellular signaling pathways, and explores the application and future prospects of the light-controlled cell signaling pathways.
