Alzheimer’s vaccine steps closer with new study!

A vaccine for Alzheimer’s disease could be trialed in humans within the next 3-5 years, after researchers from the United States and Australia have uncovered a formulation that they say successfully targets brain proteins that play a role in development and progression of the disease.

Study co-author Prof. Nikolai Petrovsky, of Flinders University School of Medicine in Australia, and colleagues reveal how a vaccine combination generates antibodies that target beta-amyloid and tau proteins in the brain – both of which are considered hallmarks ofAlzheimer’s disease.

Beta-amyloid is known to accumulate in the brains of people with Alzheimer’s, forming plaques, while the tau protein forms tangles. Plaques and tangles are believed to disrupt signaling between nerve cells and contribute to nerve cell death.
