Amyloid Fibrils03:03

Amyloid Fibrils

11.5K
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,...

Parkinson's Disease: Overview

1.6K
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Neural Regulation01:37

Neural Regulation

43.0K
Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Lysosomal Hydrolases01:22

Lysosomal Hydrolases

4.4K
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...

Cytoplasm01:16

Cytoplasm

86.9K
The cytoplasm consists of organelles and a framework of protein scaffolds called the cytoskeleton suspended in an aqueous solution, the cytosol. The cytosol is a rich broth of water, ions, salts, and various organic molecules.
Protein Folding and Misfolding
The cytoplasm is the location for several cellular processes, including protein synthesis and folding. The aqueous nature of the cytosol promotes protein folding such that the hydrophobic amino acid side chains are buried in the protein...

    Summary
    This summary is machine-generated.

    Autonomic failure is a key feature of alpha-synucleinopathies. The specific pattern and severity of autonomic dysfunction vary among pure autonomic failure, multiple system atrophy, dementia with Lewy bodies, and Parkinson disease.

    Area of Science:

    • Neuroscience
    • Neurology
    • Pathology

    Background:

    • Alpha-synucleinopathies encompass a spectrum of neurodegenerative disorders.
    • Autonomic failure is a significant clinical manifestation in these conditions.

    Observation:

    • The pattern and severity of autonomic dysfunction correlate with alpha-synuclein deposition and affected neuronal populations.
    • Clinical and laboratory autonomic features aid in differentiating synucleinopathies.

    Findings:

    • Distinct synucleinopathies exhibit unique autonomic involvement profiles.
    • Pure autonomic failure can evolve into synucleinopathies with motor deficits.

    Implications:

    • Understanding autonomic dysfunction aids in early diagnosis and prognosis.
    • Differentiating synucleinopathies is crucial for targeted therapeutic strategies.
