Title:  Early signs of Alzheimer's Disease caused by dysregulation of Synaptic Neurotransmission.

There are more than 5 million patients in the USA, who suffer from Alzheimer's disease (AD). Cognitive decline in Alzheimer's disease is thought to be the result of disturbed neuronal communication due to synaptic dysfunction. Aggregated amyloid beta protein accumulates in AD, a process leading to impaired neuronal communication. In a series of studies we investigate why aging is the most relevant risk factor to Alzheimer’s dementia. We test the age-related changes in a set of essential synaptic proteins, which regulate vesicular neurotransmitter release from synapses and their effect on beta-amyloid secretion. Maintaining physiological synaptic function while reducing amyloid secretion may provide a breakthrough to design effective therapies that halt progression of dementia in Alzheimer's disease.
