Infectious long non-coding RNAs.

Area of Science:

• Molecular Biology
• Virology
• Genetics

Background:

• Long non-coding RNAs (lncRNAs) are a significant class of RNA molecules involved in regulating diverse biological processes.
• Infectious lncRNAs represent a growing area of research, influencing host-pathogen interactions and disease pathogenesis.
• Understanding the role of lncRNAs in infection is crucial for advancing molecular biology and developing novel therapeutic approaches.

Purpose of the Study:

• To review and classify infectious long non-coding RNAs (lncRNAs).
• To elucidate the pathogenesis and impact of infectious lncRNAs on host organisms.
• To explore the potential therapeutic applications of lncRNAs in infectious diseases.

Main Methods:

• Literature review and synthesis of existing research on infectious lncRNAs.
• Classification of infectious lncRNAs into dependent and independent categories based on their replication mechanisms.
• Analysis of the structural and sequential information within lncRNAs driving host factor interactions.

Main Results:

• Infectious lncRNAs are categorized into 'dependent' (e.g., satellite RNA, Hepatitis D virus, viral lncRNAs) requiring helper viruses, and 'independent' (e.g., viroids) capable of self-replication.
• Despite lacking protein-coding capacity, lncRNAs possess intrinsic information for specific host factor interactions.
• These interactions modulate various cellular functions, impacting the overall health of the infected organism.

Conclusions:

• Infectious lncRNAs play a critical role in pathogenesis and host-pathogen dynamics.
• The study of lncRNAs challenges the traditional central dogma of molecular biology.
• Emerging insights into lncRNAs open new avenues for therapeutic strategies against infectious diseases.
