Introduction to Virus

2.9K
Viruses are unique biological entities that blur the boundary between living and non-living systems. Although they lack cellular structure and metabolic processes, they can exhibit characteristics of life when infecting a host. Their defining feature is a nucleic acid core, composed of either DNA or RNA, encapsulated within a protein coat called a capsid. This simple structure allows them to invade host cells and use their machinery for replication efficiently.Viral Structure and...

Viruses with RNA Genomes

1.5K
RNA viruses are categorized into positive-strand, negative-strand, or double-stranded groups based on their genomic structure and replication mechanisms. This classification dictates how they exploit host cellular machinery for protein synthesis and replication. Some RNA viruses also utilize reverse transcription as part of their life cycle, further diversifying their replication strategies.Positive-Strand RNA VirusesPositive-strand RNA viruses have genomes that function directly as messenger...

Subviral Agents01:29

Subviral Agents

933
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...

Cytomegalovirus Disease01:27

Cytomegalovirus Disease

102
Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...

Anthelminthic Agents01:15

Anthelminthic Agents

103
Anthelmintic drugs differ significantly from antiparasitic therapies targeting protozoa, primarily due to differences in parasite biology. Whereas most protozoal treatments act on proliferating cells, anthelmintics are typically directed against mature, nonproliferative helminths. The therapeutic approach considers the helminth's reliance on neuromuscular coordination, glucose metabolism, and microtubular integrity for survival, reproduction, and localization within the host. Most anthelmintics...

Area of Science:

  • Virology
  • Comparative Pathology
  • Infectious Diseases

Background:

  • Bats host numerous viruses with pandemic potential.
  • Understanding bat-virus interactions is crucial for public health.
  • Previous research lacked comprehensive models for studying these interactions.

Purpose of the Study:

  • To investigate bat-virus interactions using a novel organoid system.
  • To assess the potential for viral spillover from bats to other species.
  • To identify key factors influencing cross-species viral transmission.

Main Methods:

  • Development of a diverse panel of bat organoids representing various tissues.
  • Infection of organoids with a range of bat-associated viruses.
  • Analysis of viral replication, host response, and cell tropism within organoids.
  • Comparative analysis across different organoid types to identify species-specific vulnerabilities.

Main Results:

  • Organoids successfully recapitulated key aspects of bat-virus interactions.
  • Demonstrated differential susceptibility of various bat organoid types to viral infection.
  • Identified specific cell types and pathways involved in viral entry and replication.
  • Provided evidence for the potential of certain bat viruses to infect and replicate in non-bat derived organoids.

Conclusions:

  • A diverse organoid panel is a powerful tool for studying bat-virus dynamics.
  • Bat organoids reveal species-specific interactions and susceptibility to viral infection.
  • Findings underscore the importance of bats as reservoirs for viruses with zoonotic potential.
  • This model system can inform strategies for pandemic preparedness and prevention.
