- Investigate mechanisms of self-directed antibody and lymphocyte generation in Chagas heart disease.
- Evaluate evidence supporting these autoimmune mechanisms.
- Determine implications of autoimmunity for cardiac inflammation.
Main Methods:
- Review of existing literature on Chagas disease and autoimmunity.
- Analysis of proposed etiological mechanisms.
- Synthesis of evidence for autoimmune involvement.
Main Results:
- Several potential mechanisms for generating cardiac autoimmunity exist.
- Evidence supporting these mechanisms in Chagas disease varies.

Conclusions:
- The contribution of cardiac autoimmunity to Chagas heart disease requires further investigation.
- Understanding autoimmune mechanisms is crucial for comprehending disease progression.
- Further research is needed to clarify the interplay between autoimmunity and inflammation.
Abstract:
The possibility that cardiac autoimmunity contributes to the pathogenesis of Chagas heart disease is controversial. In this paper, we address the following questions regarding the genesis of autoimmunity in Chagas heart disease: (i) What mechanism(s) are potentially responsible for the generation of self-directed antibodies and lymphocytes? (ii) What is the evidence that any of these mechanisms actually can occur? (iii) What are the implications of the presence of autoimmunity for other mechanisms of cardiac inflammation?
