Objective: The most common multifactorial neurodegenerative disorder occurring in old age
is Alzheimer’s disease. The neuropathological hallmarks of that disorder are amyloid plaques with the
presence of β -amyloid aggregates, intraneuronal tau protein tangles, and chronic inflammation. Brain
cells such as microglia and astrocytes are inflammatory cells associated with Alzheimer’s disease and
involved in the production of inflammatory mediators, such as cytokines and chemokines. Chemokines
consist of a large family of protein mediators with low molecular weight, which able to control the migration
and residence of all immune cells. In pathological conditions, such as Alzheimer’s disease,
chemokines contribute to the inflammatory response by recruiting T cells and controlling microglia/
Methods: The present study focuses on the role that chemokines and their receptors play in Alzheimer's
disease and in processes such as inflammation and oxidative stress.
Results: Chemokines are important mediators in AD and inflammation. They promote Aβ deposition
and TAU hyperphosphorylation aggravating and increasing the progression of AD. Moreover, they
affect the processing of senile plaques and produce abnormal TAU phosphorylation.
Conclusion: There is no cure for AD but the therapeutic potential of chemokines to control the development
of the disease may be a field of study to consider in the future.
