Research Abstract

Fluorescence imaging could be the most powerful technique available for observing spatial and temporal dynamics of molecular processes in living cells and living individuals, if fluorescent probes for the relevant cellular signaling processes become available. In the present research project, we have developed genetically encoded fluorescent indicators for cellular signaling processes, such as reactive oxygen species and cyclic nucleotides, and also developed molecular tool to manipulate cellular signaling processes with light.
