Amyloid Fibrils03:03

Amyloid Fibrils

11.4K
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,...

Autophagy01:27

Autophagy

5.5K
Autophagy is a self-digesting process by which a cell protects itself from threats both within and outside the cell, ranging from abnormal proteins to invading bacteria. In this process, obsolete components of the cell and invading microbes are degraded by hydrolytic enzymes active in an acidic environment of the lysosomal lumen.
An autophagic pathway consists of a series of signaling events activated in response to diverse stress and physiological conditions such as food deprivation,...

Delivery Pathways to the Lysosome

8.6K
Eukaryotic cells use different mechanisms to eliminate toxic waste obsolete and worn-out substances. Lysosomes play a pivotal role in this, and hence, these substances are carried to the lysosome from other parts of the cell and extracellular space through different pathways. The most elaborately studied pathways to the lysosome are the endocytic pathways.
Endocytosis
In endocytosis, the cell membrane takes up macromolecules and particles from the surrounding medium. Clathrin-mediated...

Autophagic Cell Death01:18

Autophagic Cell Death

4.1K
Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.
Autophagy and Apoptosis
Autophagy can activate apoptosis. In normal conditions, the autophagy activating protein Beclin-1 and...

Lysosomal Hydrolases01:22

Lysosomal Hydrolases

4.3K
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,...

Area of Science:

  • Neuroscience
  • Molecular Biology
  • Pathology

Background:

  • Prion diseases, or transmissible spongiform encephalopathies, are fatal neurodegenerative conditions.
  • Pathogenesis involves the misfolding of cellular prion proteins (PrPC) into pathogenic isoforms (PrPSc).
  • Histopathological hallmarks include spongiform degeneration and PrPSc deposition.

Purpose of the Study:

  • To summarize research on prion diseases, focusing on PrPC structure, function, and PrPSc formation.
  • To review the role of autophagy in prion disease pathogenesis and clearance.
  • To identify potential pharmaceutical targets related to autophagy in prion diseases.

Main Methods:

  • Review of existing literature on prion protein structure, function, and disease mechanisms.
  • Analysis of studies investigating autophagic markers (p62, LC3) in prion disease models.
  • Synthesis of recent advances in understanding autophagy's role in prion disease.

Main Results:

  • Prion protein misfolding (PrPC to PrPSc) is central to pathogenesis.
  • Autophagic markers like p62 and LC3 are upregulated in prion disease models.
  • Autophagy plays a significant role in prion protein processing and clearance.

Conclusions:

  • Understanding prion protein spread, transport, and recycling is crucial.
  • The relationship between prion clearance and autophagy is a key area for therapeutic intervention.
  • Targeting autophagy pathways offers potential strategies for treating prion diseases.
