Amyloids are abnormal protein aggregates that can accumulate in various tissues and organs in the body. They are formed when proteins misfold and stick together, creating long, fibrous structures. This process can disrupt normal cellular functions and lead to diseases, such as Alzheimer's disease and Parkinson's disease. In healthy individuals, proteins maintain their proper shape and function. However, when amyloids form, they can cause damage to cells and tissues, leading to inflammation and organ dysfunction. Research is ongoing to understand the mechanisms behind amyloid formation and to develop potential treatments for amyloid-related diseases.
