Immunologic response in chickens from different genetic lines to Rous sarcoma virus
Cancer Detection and Prevention
|January 1, 1982
Summary
Chickens that developed early, sustained levels of anti-Rous sarcoma virus (RSV) factors in their blood were able to completely regress tumors. This indicates a strong association between immune response and tumor regression in chickens challenged with RSV.
Area of Science:
- Immunology
- Virology
- Oncology
Background:
- Rous sarcoma virus (RSV) is a known oncogenic virus.
- Understanding the host immune response to RSV is crucial for developing effective cancer therapies.
Purpose of the Study:
- To investigate the humoral immunologic response in chickens following challenge with Rous sarcoma virus.
- To determine the association between anti-RSV factors and tumor regression in chickens.
Main Methods:
- Twelve young chickens from Tumor Progressor and Tumor Regressor Lines were inoculated with RSV.
- Serum samples were collected on days 1, 10, 15, and 20 post-inoculation.
- Serum neutralization tests were performed to detect anti-RSV factors.
Main Results:
- A strong association was observed between the presence of anti-RSV factors and tumor regression.
- Early, increasing, and sustained levels of anti-RSV factors correlated with complete tumor regression.
Conclusions:
- The presence of biologically active anti-RSV factors is strongly associated with the chicken's ability to regress Rous sarcoma.
- Humoral immune response plays a significant role in controlling RSV-induced tumor growth.
