The ability of cytokines to influence cerebral functions and to induce the
development of behavioral alterations is well established in conditions of acute
or chronic high-grade activation of the innate immune system. Recent evidence
suggests that the release of these immune mediators during chronic low-grade
endogenous inflammatory processes may also contribute to the development of
behavioral alterations. Metabolic disorders, including obesity, type 2 diabetes
and the metabolic syndrome, represent examples of those conditions which are both
characterized by a chronic low-grade inflammatory state and an increased
prevalence of behavioral disorders. In metabolic disorders, the increased
production of acute-phase proteins and cytokines (e.g. C-reactive protein,
interleukin-6 and tumor necrosis factor-α), but at relatively low levels, may
promote and contribute to the development of behavioral symptoms, including
depressive symptoms, cognitive impairment, fatigue, sleep problems and pain. This
hypothesis is supported by a growing literature referring both to experimental
and clinical findings that will be reviewed here.
