Simian AIDS--evidence for a retroviral etiology

Insights

A simian model of acquired immunodeficiency (SAIDS) in macaques closely resembles human AIDS. Researchers identified an infectious type D retrovirus as the primary cause of SAIDS, offering insights into human AIDS.

Area of Science:

  • Veterinary Pathology
  • Primatology
  • Retroviral Research

Background:

  • Simian acquired immunodeficiency syndrome (SAIDS) is an endemic disease in US macaque colonies.
  • SAIDS shares clinical and pathological similarities with human acquired immunodeficiency syndrome (AIDS).

Purpose of the Study:

  • To review the key features of the simian model of acquired immunodeficiency (SAIDS).
  • To discuss the relevance of SAIDS findings for understanding human AIDS.

Main Methods:

  • Review of existing literature and case studies on SAIDS in macaques.
  • Identification and characterization of the causative retrovirus.

Main Results:

  • SAIDS in macaques mirrors human AIDS in clinical signs, pathology, and immune dysfunction.
  • An infectious type D retrovirus, distinct from Mason-Pfizer monkey virus, was identified as the primary SAIDS agent.

Conclusions:

  • The macaque SAIDS model is highly relevant for studying human AIDS.
  • Understanding the type D retrovirus in SAIDS can inform human AIDS research.

Retrovirus Life Cycles01:10

Retrovirus Life Cycles

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 retrovirus to...

Retroviruses

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’...

Mechanisms of Retrovirus-induced Cancers

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...

Rous Sarcoma Virus (RSV) and Cancer

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

Amebiasis01:28

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
