Signal Transduction refers to the process by which cells perceive
their environmental or internal status and react to such stimuli with
appropiate physiological responses. Cytokines, such as Tumor Necrosis
Factor (TNF), thereby bind to their respective receptors elicting a
signal that is propagated, amplificated and integrated, finally
leading to altered gene expression or protein activity. This can cause
the cell, for example, to differentiate in oder to fulfill a specific task or to die.
The dynamic behavior is not only hard to predict, but sometimes even
hard to understand, as signal tranduction is a highly non-linear
process. Mathematical modeling and Systems Theory can significantly
aid in understanding the molecular mechanisms and the underlying
design principles in network structure and dynamics that execute
signal transduction.
In collaboration with the Institute for Cell Biology and Immunology in
Stuttgart we are investigating those principles at the
example of the signal transduction elicted by TNF. However, some of those
pathways can also be triggered by additonal signals, or a crosstalk
with other signaling pathways might exists extending the realm of our
interest.
