Systems Biology Networking Approach to Immunology

I am looking for a method of mapping out and visualizing cellular events in a disease pathway via a software program, preferably an open source program. I am aware of programs such as Cytoskape, but it seems built more for protein interaction and genetic networking. If anyone knows a method of doing such a thing, please let me know. It would be useful for instance to visualize all the cellular and cytokine pathways in and inflammatory process so that you can visualize the disease pathway all in one place.
