CpG DNA Therapy For Alzheimer Disease

Summary:
Researchers have found that CpG DNA may be a therapeutic candidate for treatment of Alzheimer disease.

Dr. Yukiko Doi and colleagues at Nagoya University have found that CpG DNA may be a therapeutic candidate for treatment of Alzheimer disease. They report their data in the November 2009 issue of The American Journal of Pathology.

Alzheimer disease is the most common form of dementia, affecting approximately 1.6% of the population in the United States (nearly 19% in the 75-84 age group). It is an incurable, degenerate, and terminal disease thought to be caused by accumulation of oligomeric amyloid β (oAβ).

Microglia are the resident immune cells in the central nervous system; they remove damaged neurons, plaques, and infectious agents from the brain and spinal cord. Microglia cluster around senile Aβplaques in Alzheimer disease patients; however, the role of microglia in oAβtoxicity remains unclear. Doi et al discovered that microglial activation with unmethylated CpG DNA, which binds to an immune receptor on microglia, prevented oAβtoxicity and enhanced oAβ peptide clearance in culture. Furthermore, injection of CpG DNA directly into the brain mitigated both cognitive impairment and learning defects in a mouse model of Alzheimer disease. CpG DNA may therefore be a therapeutic candidate for treatment of Alzheimer disease.

Dr. Doi and colleagues conclude that "CpG, especially class B and C, may also be effective therapeutic agents against oAβ1-42 neurotoxicity in [Alzheimer disease]."
