Résumé

Systems Biology deals with the experimental and theoretical study of interactions within biological regulatory networks. The theme of this workshop is at the core of the rapidly developing field of Systems Biology as it pertained to the structural organization of cellular regulatory networks, and to the various modes of dynamical behavior associated with such regulatory interactions. In regard to the first aspect, a session was devoted to interactome networks. The dynamical aspects were considered in regulatory networks involved in development and differentiation, cellular signaling, circadian clocks, and the cell cycle. A session was also devoted to the regulatory structure and dynamics of immune networks.

Of the 19 participants who took part in the Workshop, three were post-docs; 14 came from Europe (5 from France, 5 from Belgium, 3 from England, and 1 from Germany), 4 came from the USA, and 1 from India. Participants coming from a variety of fields had either an experimental or a theoretical background. This allowed for most fruitful interactions between leading experimentalists and theoreticians developing models for cellular regulatory networks closely related to experimental observations. The success of the workshop was made possible thanks to the exceptional facilities and the harmonious, truly unique environment of the Fondation des Treilles.
