Researchers have engineered a vaccine using virus-like particles that target Tau tangles in mouse models of Alzheimer's disease. Following the administration of the vaccine, the mice developed antibodies that cleared tau proteins, with the response lasting for a month. The mice also showed improvements in memory based tests and had less brain shrinkage than their peers who did not receive the vaccine. This suggests the vaccine prevented apoptosis. Researchers hope to move the vaccine to human clinical trials in the future.
