Chemokine profile in Alzheimer’s disease: Results from a Mexican population

Abstract Alzheimer’s Disease (AD) is the main cause of dementia worldwide. Inflammatory cytokines and chemokines are related to different stages of AD and may be related to the progression of the disease. A Case-control study of AD patients healthy, age and sex-matched controls was carried out at the University Hospital “Dr. Jose E. Gonzalez”, UANL. Cytokines and chemokines were measured from blood samples taken from the cubital vein after 8 h of fast. We included 78 subjects from which 29 had AD and 49 were healthy controls. CTACK (p = 0.003), MIG (p = 0.043) and SDF-1α (p = 0.001) were increased in subjects with AD, whereas no change was observed in other cytokines and chemokines. CTACK, MIG and SDF-1α are present in the Central Nervous System and are related to inflammation and endothelial dysfunction. Longitudinal studies evaluating the change of these chemokines in AD are needed to understand their role in AD progression and possibly lead to new diagnostic and therapeutic targets.
