Cell-signalling dynamics in time and space

Boris N. Kholodenko

Spatial and temporal dynamics of signalling networks control the specificity of cellular responses to receptor stimulation. Computational models now provide insights into the mechanisms that are responsible for signal amplification, as well as the timing, amplitude, duration and spatial distribution of signalling responses.
