Using genetics to probe host-virus interactions; the mouse mammary tumor virus model

Area of Science:

• Immunogenetics
• Virology
• Genomics

Background:

• Genetic variation exists in host susceptibility to viral infections.
• Understanding these genetic factors is crucial for elucidating infection mechanisms and developing treatments.
• Mice are valuable models due to well-characterized strains and genetic manipulation capabilities.

Purpose of the Study:

• To review the application of genetic approaches in studying viral infections.
• To highlight the dissection of viral infection pathways and host responses using genetic analysis.
• To focus on the mouse mammary tumor virus (MMTV) as a model retrovirus.

Main Methods:

• Utilizing genetically well-characterized inbred mouse strains.
• Employing targeted germ line mutations for genetic analysis.
• Reviewing studies focused on the mouse mammary tumor virus (MMTV).

Main Results:

• Genetic studies have successfully dissected the MMTV infection pathway.
• Host genetic factors influencing MMTV infection and pathogenesis have been identified.
• Insights into host-pathogen interactions have been gained through genetic approaches.

Conclusions:

• Genetics provides powerful tools for understanding viral infections and host responses.
• The mouse model is instrumental in identifying genes that control susceptibility to viral pathogens.
• This knowledge can inform the development of novel antiviral therapies and preventative strategies.
