Invited Symposium: Cytokines, Monoamines and Behavior
Watkins, L. R. (Department of Psychology, University of Colorado, USA)
The brain and the immune system form a bi-directional communication pathway in which infection and injury in the periphery lead to immune signals to the CNS, and the CNS in turn orchestrates host defensive responses which in turn involve alterations in the periphery. Interleukin-1 (IL-1) is involved in this loop both in the periphery as a key signal to the CNS and in the CNS itself. Data will be reviewed which indicate that stressors may be able to activate this same loop that is activated by infectious agent, perhaps by inducing IL-1 in brain. Furthermore, this activation does not seem to be sensitive to stressor controllability, and so may be induced by physical properties of stressors per se.
