Amyloid is a term that refers to a group of proteins that become abnormally folded and aggregate into insoluble fibrils, which can accumulate in tissues and organs. While amyloid proteins play essential roles in the body under normal circumstances, their misfolding and accumulation are linked to a range of serious health conditions, particularly neurodegenerative diseases like Alzheimer disease.
Amyloid proteins are normally soluble proteins that, when misfolded, form insoluble fibrils that can deposit in various tissues. These proteins are made up of long chains of amino acids and usually fold into a specific three dimensional structure that is necessary for their function. Amyloid proteins are a normal part of the body biological processes, but when they accumulate excessively or inappropriately, they can become toxic and cause organ damage. There are several different types of amyloid proteins, depending on the underlying protein that misfolds and aggregates. Some of the most well known amyloid proteins. Amyloid beta is a fragment of a larger protein called amyloid precursor protein. These plaques are one of the hallmarks of alzheimer disease and contribute to neurodegeneration by disrupting communication between neurons and inducing inflammation. This form of amyloid is associated with plasma cells and the production of abnormal immunoglobulin light chains. Amyloidosis can cause organ failure and is often a complication of multiple myeloma, a type of blood cancer. This form of amyloidosis occurs due to the accumulation of serum amyloid protein, which is produced in response to chronic inflammation. Amyloidosis is often associated with chronic inflammatory diseases like rheumatoid arthritis or tuberculosis. Amyloid deposits can occur in almost any tissue or organ and the consequences of these deposits are primarily determined by where the amyloid accumulates. The presence of amyloid beta plaques is a diagnostic hallmark of alzheimer, but their exact role in the disease process remains an area of active research. In amyloidosis, amyloid fibrils can deposit in the heart muscle, leading to restrictive cardiomyopathy. This condition makes the heart walls stiff and less able to expand and contract, resulting in heart failure symptoms such as shortness of breath, fatigue, and swelling in the legs and abdomen. Amyloid deposits in the kidneys can cause nephrotic syndrome, a condition characterized by protein loss in the urine, swelling, and kidney dysfunction. In amyloidosis, amyloid deposits in the liver and spleen can result in organ enlargement hepatosplenomegaly impairing. Amyloid proteins play a critical role in both health and disease. While they are essential to normal physiological functions in the body, their abnormal accumulation can lead to a wide range of diseases, from neurodegenerative disorders like Alzheimer to systemic conditions such as amyloidosis [1-4].
The deposition of amyloid fibrils in tissues and organs can have devastating effects on function, contributing to cognitive decline, organ failure, and a reduction in overall quality of life. In the case of alzheimer disease, amyloid beta plaques have become iconic markers of the condition, although the precise mechanisms by which they contribute to disease progression remain an area of intense research. Similarly, in conditions like transthyretin amyloidosis and light chain amyloidosis, amyloid deposits in vital organs such as the heart and kidneys can lead to life-threatening complications, underscoring the urgency for effective diagnostics and treatments.
