[The immunodeficiency retrovirus in man and primates]
Bulletin De L'Academie Nationale De Medecine
|February 1, 1989
Abstract:
Human immunodeficiency viruses, HIV-1 and HIV-2, are similar, by genome structure, nucleotide sequences and pathogenicity, to retroviruses existing in various primates, SIVs. The possibility is discussed that the human viruses have their origin in accidental transmission of some monkey viruses to man. Studies of SIVs also suggest that the pathogenic effect not only depends on the virus strain, but also on the host species.
Insights
Human immunodeficiency viruses (HIVs) likely originated from simian immunodeficiency viruses (SIVs) in primates. Pathogenicity depends on both the specific virus strain and the host species, impacting disease severity.
Area of Science:
- Virology
- Primate Retroviruses
- Molecular Biology
Context:
- Human immunodeficiency viruses (HIV-1 and HIV-2) share similarities with simian immunodeficiency viruses (SIVs) found in primates.
- Genome structure, nucleotide sequences, and pathogenicity link HIVs and SIVs.
Purpose:
- To explore the potential zoonotic origin of HIVs from primate SIVs.
- To investigate the factors influencing the pathogenicity of retroviral infections.
Summary:
- HIV-1 and HIV-2 exhibit significant genetic and pathogenic resemblance to SIVs, suggesting a common ancestry.
- The transmission of SIVs from monkeys to humans is proposed as a likely origin for HIV.
- Research indicates that viral pathogenicity is a complex interplay between the specific virus strain and the host species' genetic makeup.
Impact:
- Provides insights into the evolutionary origins of human retroviral pathogens.
- Highlights the importance of host-pathogen interactions in determining disease outcomes.
- Informs future research on retroviral emergence and control strategies.
