Amyloid Fibrils03:03

Amyloid Fibrils

12.8K
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,...

Overview of Protein Metabolism01:21

Overview of Protein Metabolism

4.5K
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 Complex Assembly02:41

Protein Complex Assembly

17.0K
Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types.  Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.
Many viruses self-assemble into a fully functional unit using the infected host cell to...

Abnormal Proliferation02:23

Abnormal Proliferation

5.4K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Protein Complexes with Interchangeable Parts01:57

Protein Complexes with Interchangeable Parts

3.0K
Groups of proteins may form a complex where each protein in this complex has a different role in the overall execution of the complex’s function. Often some of the proteins in the complex can be replaced by a closely related variant to give a complex that contains many of the same components yet is functionally distinct.
The SCF ubiquitin ligase is a protein complex of five individual proteins. This complex attaches ubiquitin to other target proteins to mark them for degradation. In order...

    Summary
    This summary is machine-generated.

    Malignant proteins, not just cancer, can spread harmfully in the brain. Research into protein aggregation in Alzheimer's, Parkinson's, CTE, and ALS is a vital new neuroscience frontier.

    Area of Science:

    • Neuroscience
    • Molecular Biology
    • Pathology

    • The term "malignant" is commonly associated with cancer.
    • However, certain proteins can exhibit harmful, spreading behavior in the brain.

    Purpose of the Study:

    • To explore the concept of "malignant" proteins in the context of neurodegenerative diseases.
    • To highlight the significance of studying protein aggregation and spread in brain disorders.

    Main Methods:

    • Analysis of protein aggregation mechanisms.
    • Investigation of protein spread in neurodegenerative conditions.
    • Examination of protein-induced brain cell death.

    Main Results:

    • Proteins like PrP, amyloid beta, and tau can aggregate and spread throughout the brain.
    • This protein aggregation and spread contribute to the pathology of neurodegenerative diseases.
    • These processes lead to the death of brain cells.

    Conclusions:

    • Proteins can be considered "malignant" due to their harmful spreading behavior in the brain.
    • Understanding protein aggregation is a critical new direction in neuroscience research.
