Summary
Amyloid disorders involve abnormal protein buildup. While current treatments manage symptoms, new therapies targeting amyloid fibril formation offer future hope for effective disease prevention and treatment.
Area of Science:
- Biochemistry
- Pathology
- Pharmacology
Background:
- Amyloid disorders, also known as proteinopathy or amyloidosis, are characterized by the accumulation of abnormal protein aggregates forming cross-β-sheet amyloid fibrils in various organs.
- These fibrils are often composed of misfolded or improperly folded proteins.
- Current treatments for amyloid diseases primarily focus on symptom management rather than addressing the underlying disease process.
Purpose of the Study:
- To review current understanding of amyloid disease biology.
- To highlight recent advances in therapeutic strategies targeting amyloid fibril formation and accumulation.
- To discuss the potential of novel treatments for amyloidosis.
Main Methods:
- Literature review of recent advances in amyloidosis research.
- Analysis of emerging therapeutic modalities including small compounds, monoclonal antibodies, and gene therapy.
- Synthesis of current knowledge on amyloid disease pathogenesis and treatment.
Main Results:
- Significant progress has been made in understanding the biological mechanisms underlying amyloid diseases.
- Innovative therapies targeting the initiation and progression of amyloid fibril formation are under development.
- These novel approaches include small molecules, antibody-based therapies, and gene therapy strategies.
Conclusions:
- While most current amyloid disease therapies are symptomatic, ongoing research is identifying new therapeutic targets.
- Advances in understanding amyloidosis biology are paving the way for more effective treatments.
- Future therapeutic strategies aim to prevent or reverse the accumulation of amyloid fibrils, offering potential cures.

Overview of Protein Metabolism
1.0K
Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...

Protein Networks
3.9K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Targeted Cancer Therapies
7.5K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

Protein-protein Interfaces
12.5K
Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

The Proteasome

Eukaryotic cells can degrade proteins through several pathways. One of the most important among these is the ubiquitin-proteasome pathway. It helps the cell eliminate the misfolded, damaged, or unwarranted cytoplasmic proteins in a highly specific manner.
In this pathway, the target proteins are first tagged with small proteins called ubiquitin. This involves participation of a series of enzymes including— E1 (ubiquitin-activating enzyme), E2 (ubiquitin-conjugating enzyme), and E3...
