Research demonstrates immunization strategies targeting tau proteins could improve outcomes in Alzheimer's disease, suggesting new therapeutic options.
Introduction Alzheimer's disease (AD) is characterized by the formation of senile plaques composed of amyloid-beta (Aβ) peptides and the intraneuronal accumulation of neurofibrillary tangles composed of abnormal, hyperphosphorylated tau proteins. These act in concert to drive cognitive decline, but it is widely held that tau spread correlates better with cognitive decline than does amyloid burden. Control of AD neuropathologies with active immunizations is studied as a potential therapeutic avenue because it could build innate immunity. Although most active immunization studies have focused on Aβ targets, tau and other targets continue to be explored.
