    Insights

    The viral cause of New Zealand Black (NZB) mice autoimmune disease remains unproven, though a latent virus is possible. Experimental results vary widely due to undefined mouse strains, potentially leading to inaccurate conclusions.

    Area of Science:

    • Immunology
    • Virology
    • Genetics

    Background:

    • New Zealand Black (NZB) mice are a model for autoimmune diseases.
    • The potential viral aetiology of NZB autoimmune disease has been debated.
    • Inconsistent experimental results complicate the understanding of NZB mice.

    Purpose of the Study:

    • To review evidence for and against a viral cause of NZB mice autoimmune disease.
    • To highlight the impact of mouse strain definition on experimental outcomes.
    • To caution against drawing conclusions from studies using diverse NZB mouse origins.

    Main Methods:

    • Literature review of studies on NZB mice and autoimmune disease.
    • Analysis of evidence supporting and refuting viral aetiology.
    • Discussion of experimental variability and its causes.

    Main Results:

    • The evidence for a viral aetiology in NZB mice is currently unproven.
    • A possibility remains that a virus may be present in an incomplete form.
    • Significant variability in experimental results is observed.

    Conclusions:

    • The viral aetiology of NZB mice autoimmune disease is not definitively established.
    • Inconsistent experimental findings underscore the need for standardized mouse strain definition.
    • Comparisons between studies using NZB mice from different sources may yield misleading conclusions.

    Viral Recombination00:57

    Viral Recombination

    Cells are sometimes infected by more than one virus at once. When two viruses disassemble to expose their genomes for replication in the same cell, similar regions of their genomes can pair together and exchange sequences in a process called recombination. Alternatively, viruses with segmented genomes can swap segments in a process called reassortment.

    Viruses with RNA Genomes

    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

    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...
    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...
    Arboviral Encephalitis01:25

    Arboviral Encephalitis

    Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
