Alzheimer’s disease is the most common neurodegenerative disorder characterized by the presence of β-amyloid aggregates deposited as senile plaques and by the presence of neurofibrillary tangles of tau protein. To date, there is a broad consensus on the idea that neuroinflammation is one of the most important component in Alzheimer’s disease pathogenesis. Chemokines and their receptors, beside the well-known role in the immune system, are widely expressed in the nervous system, where they play a significant role in the neuroinflammatory processes.

Among mediators of inflammation, chemokines play a pivotal role in the neuroinflammatory process related to Alzheimer's disease (AD). The chemokine Bv8/prokineticin 2 (PROK2) is a critical player in inflammatory and neuroinflammatory diseases and has been demonstrated to be involved in A beta toxicity. The aim of the present study was to extend the research to rats chronically intracerebroventricularly (i.c.v.) injected with A beta, to an AD transgenic mouse model, and subsequently to AD patients, mainly with the aim of detecting a potential biomarker.
