[Prion diseases: current views].

Area of Science:

• Neuroscience
• Pathology
• Infectious Diseases

Background:

• Prion diseases are fatal neurodegenerative disorders affecting humans and animals.
• These diseases are caused by prions, which are infectious, low-molecular-weight, anucleinic proteins resistant to inactivation.
• Examples in humans include fatal familial insomnia, Creutzfeldt-Jakob disease, kuru, and Gerstmann-Sträussler-Scheinker syndrome.

Discussion:

• Prions have a unique ability to alter their tertiary conformation, leading to a pathological, infectious form.
• The review discusses the pathogenesis, morphological characteristics, and clinical presentations of prion diseases.
• Principles of diagnosis and treatment strategies are also covered.

Key Insights:

• Prion diseases are characterized by the misfolding of prion proteins into infectious agents.
• Understanding prion protein conformation is crucial for disease mechanism elucidation.
• The review synthesizes current knowledge on diagnosis and therapeutic approaches.

Outlook:

• Further research into prion protein structure and function is needed.
• Development of novel diagnostic tools and effective treatments remains a priority.
• Preventive strategies against prion transmission require continued investigation.
