In addition to the role that cytokines (growth factors, interleukins, instructive factors) play in regulating neuronal
survival, growth and gène expression during development, récent évidence suggests that these intercellular signals can
also control similar functions in the normal, as well as the injured, adult nervous system. Some of this evidence is
summarized here, with particular emphasis on the potential role of cytokines in synaptic function and plasticity
