Immunity against avian sarcomas: a review
Israel Journal of Medical Sciences
|April 1, 1976
Summary
Chickens with avian sarcoma virus tumors develop immune responses targeting viral and nonviral antigens. This study reviews effector mechanisms and the roles of the bursal and thymic systems in avian antitumor immunity.
Area of Science:
- Immunology
- Virology
- Oncology
Background:
- Avian sarcoma virus (ASV) induces tumors in animals.
- Tumors elicit both cellular and humoral immune responses.
- Immune responses target viral and nonviral antigens.
Purpose of the Study:
- Summarize recent developments in avian antitumor immunity.
- Focus on effector mechanisms in chickens.
- Investigate the role of bursal and thymic systems.
Main Methods:
- Analysis of structural and antigenic properties of ASV.
- Detection of virus-induced tumor-associated antigens (TAAs).
- In vivo and in vitro methods for TAA detection.
Main Results:
- Animals mount significant antitumor immune responses.
- TAAs are crucial targets for immune attack.
- Bursal and thymic systems play distinct roles in immunity.
Conclusions:
- Avian antitumor immunity is complex, involving multiple effector mechanisms.
- Understanding TAAs and immune system components is vital for controlling ASV-induced tumors.
- Further research can advance avian cancer immunotherapy.
