The accumulation of amyloid beta plaques is a hallmark of Alzheimer's disease.
Elevated a-beta levels in the cerebrospinal fluid may indicate Alzheimer's disease.
Researchers are studying the role of a-beta peptide in neurodegenerative diseases.
The mechanism of a-beta toxicity in the brain is still not fully understood.
The process of a-beta aggregation is thought to contribute to neuronal damage.
