Amyloid peptides are small protein fragments that can aggregate and form abnormal clumps in the body. These aggregates are often associated with various diseases, particularly neurodegenerative disorders like Alzheimer's disease. In Alzheimer's, the accumulation of amyloid-beta peptides in the brain is believed to disrupt cell function and contribute to cognitive decline. The formation of amyloid peptides occurs when proteins misfold and stick together, creating fibrils that can be toxic to cells. Research into amyloid peptides aims to understand their role in disease progression and to develop potential treatments that can prevent or reverse their harmful effects.
