Research Abstract

Adaptive and oscillatory response consisting of multiple time-scales was analyzed by taking an example from cAMP-induced cAMP relay-response in Dictyostelium. Based on quantitative live-cell imaging analysis, we found that the first peak can be considered as an output from a module that realizes fold-change detection. The prolonged response on the other hand depends on the absolute concentration of extracellular cAMP and appears to be dependent on F-actin mediated feedaback. We discussed the relationship between these observed properties and robustness of cell-cell signaling.
