[Possible intervention of immune mechanisms in the genesis and course of human atherosclerosis]
Insights
Immunoglobulins and complement proteins bind to arterial lesions in atherosclerosis patients. This binding is more pronounced in arteries supplying infarcted areas, suggesting a role in cardiovascular disease progression.
Area of Science:
- Cardiovascular pathology
- Immunohistochemistry
- Atherosclerosis research
Context:
- Investigating the role of immune components in atherosclerosis.
- Examining arterial tissues from patients with myocardial or cerebral infarction.
- Comparing findings with non-atherosclerotic disease controls.
Purpose:
- To determine the presence and extent of immunoglobulin and complement deposition in atherosclerotic lesions.
- To compare immune complex deposition in arteries from atherosclerosis patients versus controls.
- To assess if binding intensity correlates with infarction or arterial pathology.
Summary:
- Direct immunoenzymatic tests revealed immunoglobulins and complement bound to all examined atherosclerotic lesions, elastic fiber alterations, and lipid infiltrations.
- Binding was observed in both atherosclerosis and non-atherosclerosis groups, but was generally more intensive in atherosclerosis patients.
- Arteries supplying infarcted areas showed more intensive binding, indicating a potential link between immune deposition and ischemic events.
Impact:
- Provides evidence for immune system involvement in the pathogenesis of atherosclerosis.
- Suggests potential diagnostic or therapeutic targets related to immunoglobulin and complement pathways.
- Highlights the association between immune deposition and ischemic complications in cardiovascular disease.
Abstract:
Aortas, coronary and carotid arteries from 31 patients who died of myocardial or cerebral infarction were examined by direct immunoenzymatic tests (using peroxidase-labelled anti human IgG sheep Fab or anti human complement sheep IgG) and compared to those of 9 patients who died of non atherosclerotic diseases. Immunoglobulins and complement bound to all atherosclerotic lesions, all elastic fiber alterations, all lipid infiltration in patients who died of atherosclerosis, as well as in patients who died of various other causes. Binding was generally more intensive in patients who died of atherosclerosis and in arteries irrigating infarcted areas. These data are discussed.
