Abstract
The occurrence of interleukin-1 (IL-1) in the brain is usually associated with pathological events of the central nervous system (CNS), although there is evidence that the cytokine may also play a role in physiological processes. The ability of IL-1 to induce a damage in the CNS is dependent on the type of cell producing the cytokine and the length of exposure; on this regard, it is possible to distinguish between the minutes-to-days and the days-to-years time-frames. While the long-term action of IL-1 in the CNS is unambiguously associated with the activation of glial cells as well as the occurrence of chronic disorders such as Alzheimer's disease and AIDS-related dementia, it remains to be established whether glial cells, 'interleukinergic' neurons or both cell types are involved in CNS responses to acute noxiae, such as physical stress (restrain stress, nociceptive stimulation) or immune-inflammatory challenges.
