Insights

Avian sarcoma and leukosis virus (ASLV) research reveals cellular receptors crucial for retroviral entry. Studies identified ASLV receptor genes and uncovered a novel virus-cell fusion mechanism.

Area of Science:

  • Virology
  • Molecular Biology
  • Cell Biology

Background:

  • Avian sarcoma and leukosis virus (ASLV) interactions with cellular receptors serve as a key model for understanding retroviral entry.
  • Early research focused on genetic factors influencing chicken susceptibility to ASLV subgroups.

Purpose of the Study:

  • To review the historical and ongoing contributions of ASLV-receptor studies to understanding retroviral entry mechanisms.
  • To highlight key findings, including the identification of ASLV receptor genes and the elucidation of virus-cell fusion.

Main Methods:

  • Genetic analysis of chicken lines to determine susceptibility to ASLV subgroups.
  • Identification and characterization of genes encoding cellular receptors for ASLV.
  • Investigation of viral interference as a consequence of receptor usage.

Main Results:

  • Defined three autosomal recessive genes predicted to encode ASLV cellular receptors.
  • Established the concept of viral interference, where receptor occupancy prevents reinfection.
  • Elucidated an unprecedented mechanism of virus-cell fusion mediated by ASLV receptors.

Conclusions:

  • ASLV-receptor system research has significantly advanced the understanding of retroviral entry.
  • Identification of receptor genes and fusion mechanisms provides fundamental insights into virus-host interactions.

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.

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.

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...
