Amyloid deposition refers to the accumulation of abnormal proteins known as amyloid fibrils in the tissues of the body. This process occurs in various diseases, including Alzheimer's disease, Parkinson's disease, and type 2 diabetes. Amyloid fibrils are formed from misfolded proteins and can accumulate in organs such as the brain, heart, kidneys, and liver, leading to tissue damage and dysfunction. Research in this area aims to understand the mechanisms of amyloid deposition, develop diagnostic tools to detect amyloid accumulation early, and explore potential therapeutic strategies to prevent or reverse this process.
