Summary
The human immunodeficiency virus (HIV), the cause of acquired immunodeficiency syndrome (AIDS), was identified in 1983. A model for HIV pathogenicity is proposed, detailing host-virus interactions in disease progression.
Area of Science:
- Virology
- Immunology
- Epidemiology
Background:
- The etiological agent of acquired immunodeficiency syndrome (AIDS) was first isolated in 1983.
- Initial isolates were named lymphadenopathy associated virus (LAV), HTLV-III, or ARV.
- International consensus proposed the name human immunodeficiency virus (HIV) for these related viruses.
Purpose of the Study:
- To propose a general model for HIV pathogenicity.
- To explain the stepwise evolution from primary infection to disease.
Main Methods:
- Review of biological and molecular characteristics of HIV isolates.
- Analysis of epidemiological and clinical observations.
- Development of a host-virus interaction model.
Main Results:
- Confirmation that LAV, HTLV-III, and ARV are isolates of the same virus, HIV.
- A proposed model illustrating the complex pathway of pathogenicity.
- Understanding the stepwise progression from infection to disease.
Conclusions:
- HIV is the causative agent of AIDS.
- A model of pathogenicity based on host-virus interactions provides insight into disease progression.
- Further research into HIV biology and host interactions is crucial for understanding and managing AIDS.

Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...

01:10Retrovirus Life Cycles
42.8K
Retroviruses have a single-stranded RNA genome that undergoes a special form of replication. Once the retrovirus has entered the host cell, an enzyme called reverse transcriptase synthesizes double-stranded DNA from the retroviral RNA genome. This DNA copy of the genome is then integrated into the host’s genome inside the nucleus via an enzyme called integrase. Consequently, the retroviral genome is transcribed into RNA whenever the host’s genome is transcribed, allowing the...

00:36Viral Mutations
32.6K
A mutation is a change in the sequence of bases of DNA or RNA in a genome. Some mutations occur during replication of the genome due to errors made by the polymerase enzymes that replicate DNA or RNA. Unlike DNA polymerase, RNA polymerase is prone to errors because it is not capable of “proofreading” its work. Viruses with RNA-based genomes, like HIV, therefore accrue mutations faster than viruses with DNA-based genomes. Because mutation and recombination provide the raw material...

01:26Size and Structure of Viral Genomes
1.2K
Viral genomes exhibit remarkable diversity in size, structure, and composition, influencing their replication strategies and interactions with host cells. These genomes consist of either DNA or RNA and may be linear or circular. Additionally, they can be single-stranded or double-stranded, with each configuration affecting how the virus propagates within a host. RNA viruses, for instance, generally have smaller genomes than DNA viruses, a factor that contributes to their high mutation rates and...
