Circulating cytokines in Alzheimer's disease

Summary

Immune factors may be involved in the pathophysiology of Alzheimer's disease (AD), a neurodegenerative disease. Since immune activation precedes immune-mediated processes, we measured plasma levels of four selective cytokines: interleukin-6 (IL-6), interleukin-12 (IL-12), interferon-alpha (IFN-α), and interferon-gamma (IFN-γ). The level of IL-6, but not other cytokines, was significantly elevated. The increase of circulating IL-6 indicates immune activation presumably related to pathophysiology of the disease.

    Making matters worse, these adipocytokines can cross the blood–brain barrier and affect the central nervous system [39,40]. Cross-sectional studies have shown proinflammatory cytokines are elevated in individuals with obesity, and play a role in dementia related neurodegeneration [41,42]. Further, in a cross-sectional study observing the role of inflammation and cognition in an elderly sample, increased IL-6 and C reactive protein correlated to increased cognitive decline [43].

    In a prospective cohort study of patients with mild to severe AD, high baseline levels of TNF-α were associated with an increase in the rate of cognitive decline (Holmes et al., 2009). In addition, increased peripheral levels of IL-6 have been reported in patients with AD in various studies (Singh and Guthikonda, 1997; Licastro et al., 2000). However, in a longitudinal study with a small sample, no significant differences were observed between AD subjects and controls with respect to the mean serum levels of IL-1β, IL-1 receptor antagonist, IL-6, TNF-α, the soluble TNF receptors types I and II, and alpha 1-antichymotrypsin (Lanzrein et al., 1998).
