Growing evidences demonstrate that chemokines and chemokine receptors are up-regulated in resident central nervous system cells during Alzheimer's disease contributing to neuroinflammation and neurodegeneration. Prokineticin 2 belongs to a new family of chemokines which recently emerged as a critical player in immune system and inflammatory diseases.

Neurotropic herpesviruses have been associated with the onset and progression of Alzheimer's disease, a common form of dementia that afflicts a large percentage of elderly individuals. Interestingly, among the neurotropic herpesviruses, herpes simplex virus-1, human herpesvirus-6A, and human herpesvirus-6B have been reported to infect several cell types present in the central nervous system and to dysregulate autophagy, a process required for homeostasis of cells, especially neurons.
