Specific antibodies halt Alzheimer's disease in mice

Antibodies that block the process of synapse disintegration in Alzheimer's disease have been identified, raising hopes for a treatment to combat early cognitive decline in the disease. Alzheimer's disease is characterized by abnormal deposits in the brain of the protein Amyloid-ß, which induces the loss of connections between neurons, called synapses. Now, scientists at University College London (UCL) have discovered that specific antibodies that block the function of a related protein, called Dkk1, are able to completely suppress the toxic effect of Amyloid-ß on synapses. The findings are published today in the Journal of Neuroscience. Patricia Salinas, from the UCL Department of Cell & Developmental Biology, who led the study, said, "These novel findings raise the possibility that targeting this secreted Dkk1 protein could offer an effective treatment to protect synapses against the toxic effect of Amyloid-ß.
