Summary
Defective Human Immunodeficiency Virus (HIV) genomes can trigger immune responses and complicate HIV pathogenesis, even during antiretroviral therapy (ART). Understanding these defective viruses is crucial for developing strategies to eliminate the HIV reservoir and achieve eradication.
Area of Science:
- Virology
- Immunology
- Genetics
Background:
- Defective Human Immunodeficiency Virus (HIV) genomes are prevalent within proviral populations.
- These defective genomes can retain the capacity for transcription and translation, producing RNA and proteins.
- Their role in immune stimulation and disease progression is an area of active research.
Purpose of the Study:
- To review the origins and characteristics of defective HIV genomes.
- To analyze their impact on innate and adaptive immunity.
- To explore their contribution to HIV pathogenesis and challenges in HIV eradication.
Main Methods:
- Literature search on defective HIV genomes (HIV-1, Lentivirus, Orthoretrovirinae, Retroviridae).
- Analysis of studies investigating transcription, translation, and immunogenicity of defective HIV RNA and proteins.
- Review of research on the role of defective genomes in HIV pathogenesis and treatment outcomes.
Main Results:
- Defective HIV genomes originate from various sources and can be transcribed and translated.
- Defective RNA and proteins can stimulate innate and adaptive immune responses.
- These elements contribute to immune hyperactivation and pathogenesis, persisting even with successful antiretroviral therapy (ART).
Conclusions:
- Defective HIV viruses pose significant challenges to reservoir elimination and HIV eradication efforts.
- Their immunomodulatory functions impact disease progression and treatment efficacy.
- Further research into defective genomes is essential for developing curative strategies against HIV.

01:51Mechanisms of Retrovirus-induced Cancers
5.0K
Retroviruses are RNA viruses that have been shown to cause cancers in diverse species, including chickens, mice, cats, and monkeys. The RNA genomes of these viruses are first reverse-transcribed into single and then double-stranded DNA (dsDNA) copies. This dsDNA called proviral DNA then integrates into the host genome. Subsequently, the host cell transcribes the proviral DNA in concert with the chromosomal DNA. This leads to the production of viral RNA and proteins that assemble at the host...

02:33Retroviruses
12.2K
Retroviruses and retrotransposons both insert copies of their genetic elements into the genome of the host cell. Thus, the viral genes are passed on when the host genome is replicated or translated. A typical retroviral DNA sequence contains 3-4 genes that encode the different proteins required for its structural assembly and function as a molecular parasite. This DNA is transcribed into a single mRNA, which is very similar in structure to conventional mRNAs, i.e., it is capped at the 5’...

45.7K
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...

01:25Immunodeficiency Diseases
909
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.

01:29Immune Response Against Viral Pathogens
752
The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

00:36Viral Mutations
32.2K
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...
