Description

Biological pathways, such as signaling networks, are a key component of biological systems
of each living cell. In fact, malfunctions of signaling pathways are linked to a number of
diseases, and components of signaling pathways are used as potential drug targets. Elucidating
the dynamic behavior of the components of pathways, and their interactions, is one of the key
research areas of systems biology.
Biological signaling networks are characterized by a large number of components and an
even larger number of parameters describing the network. Furthermore, investigations of
signaling networks are characterized by large uncertainties of the network as well as limited
availability of data due to expensive and time-consuming experiments. As such, techniques
derived from systems analysis, e.g., sensitivity analysis, experimental design, and parameter
estimation, are important tools for elucidating the mechanisms involved in signaling networks.
This Special Issue contains papers that investigate a variety of different signaling networks via
established, as well as newly developed modeling and analysis techniques.
