Signal Amplitude (IMAGE) University of Copenhagen - Niels Bohr Institute Caption As the signal amplitude of the TNF protein increases, several different synchronization modes can arise. The figure shows how different synchronizations of the TNF protein outside the cell, and the NF-kB protein inside the cell appears as a function of the oscillations in the TNF. Credit Credit: M.
