Subviral Agents01:29

Subviral Agents

Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...
Amyloid Fibrils03:03

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, normally used to...

Rabies01:28

Rabies

Rabies is a lethal zoonotic disease caused by a single-stranded, negative-sense RNA virus of the Lyssavirus genus, within the family Rhabdoviridae. Its primary mode of transmission to humans is through bites or saliva-contaminated scratches from infected mammals such as dogs, bats, raccoons, or foxes. Transmission can also occur if infectious saliva contacts abraded skin or intact mucous membranes, including the conjunctiva.Viral Entry and Early ReplicationOnce introduced at the bite or scratch...
Parkinson Disease ll: Pathophysiology01:24

Parkinson Disease ll: Pathophysiology

Parkinson disease (PD) is a progressive neurodegenerative disorder primarily affecting movement, with additional non-motor features. Its pathophysiology involves complex interactions among genetic susceptibility, environmental exposures, and cellular dysfunction, including dopaminergic neuron loss, protein aggregation, and mitochondrial impairment.Selective NeurodegenerationA key feature is the degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to reduced...
Huntington Disease l: Introduction01:21

Huntington Disease l: Introduction

Huntington disease or HD is a progressive, fatal neurodegenerative disorder inherited in an autosomal dominant pattern.PathophysiologyIt is caused by expansion of the CAG trinucleotide repeat in the HTT gene on chromosome 4 (4p16.3), producing an abnormal huntingtin protein with an expanded polyglutamine tract. This misfolded protein disrupts cellular function, leading to neuronal death. Normal alleles have ≤26 repeats, 27–35 are intermediate (risk of expansion), 36–39 show reduced penetrance,...

Area of Science:

  • Neurology
  • Neuroscience
  • Biochemistry

Background:

  • Prion diseases are fatal neurodegenerative disorders.
  • Caused by misfolded cellular prion protein (PrP^C) into infectious isoforms (PrP^Sc).
  • Manifests as sporadic, hereditary, or acquired forms, often presenting with rapidly progressive dementia and myoclonus.

Purpose of the Study:

  • To provide a comprehensive overview of prion diseases.
  • Focus on the epidemiology, pathogenesis, diagnosis, and laboratory evaluation.
  • Highlight Creutzfeldt-Jakob disease (CJD) as the most common human prion disease.

Main Methods:

  • Literature review of epidemiological data.
  • Pathogenesis review focusing on prion protein misfolding.
  • Diagnostic criteria and laboratory testing methods discussed.

Main Results:

  • Prion diseases are rare but universally fatal.
  • Epidemiological patterns vary by type (sporadic, familial, acquired).
  • Diagnostic challenges exist, with laboratory tests crucial for confirmation.

Conclusions:

  • Understanding prion disease mechanisms is key for potential therapeutics.
  • Early diagnosis and appropriate laboratory testing improve patient management.
  • Continued research is vital for CJD and other prionopathies.
