Amyloid Fibrils

Amyloid Fibrils

Amyloid Fibrils

Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining,...

Alzheimer's Disease: Overview

Alzheimer's Disease: Overview

Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

Area of Science:

Nephrology
Pathology
Biochemistry

Background:

Amyloidosis is a rare condition characterized by extracellular deposition of aggregated soluble proteins as insoluble fibrils.
This deposition leads to progressive organ dysfunction and tissue destruction.
Over 25 amyloid precursor proteins are known, highlighting the complexity of the disease.

Purpose of the Study:

To provide an overview of amyloidosis, focusing on its pathological features and diagnostic approaches.
To emphasize the significance of renal amyloidosis and the methods used for its characterization.

Main Methods:

Ultrastructural examination reveals characteristic amyloid fibril morphology.
Polarized light microscopy aids in identifying amyloid deposits due to anomalous coloration.
Immunofluorescence, immunoperoxidase staining, laser microdissection, and mass spectrometry are key techniques for typing renal amyloidosis.

Main Results:

Amyloid deposits exhibit distinct ultrastructural and optical properties.
The kidney is a frequent site for amyloid accumulation.
Advanced molecular techniques enable precise classification of amyloid types in renal tissues.

Conclusions:

Amyloidosis is a complex disease with diverse protein precursors and significant organ impact.
Accurate typing of amyloidosis, particularly renal amyloidosis, is essential for patient management.
A combination of morphological and molecular methods is vital for diagnosing and classifying amyloidosis.
