Atherosclerosis involves chronic inflammation and potential autoimmune attacks. This study presents evidence from experimental and human studies supporting autoimmune mechanisms in the development of atherosclerotic plaques.

Area of Science:

Cardiovascular Research
Immunology
Pathology

Background:

Atherosclerosis is increasingly viewed as a chronic inflammatory condition.
The influx of fat into the vessel wall is considered an 'adequate' response to various injuries.
The hypothesis of autoimmune-mediated attack on atherosclerotic lesions is gaining traction.

Purpose of the Study:

To present evidence supporting the involvement of autoimmune mechanisms in atherogenesis.
To explore the role of autoantigens and immune responses in plaque formation.
To consolidate findings from experimental models and human studies.

Main Methods:

Review of experimental models investigating autoimmune responses in atherosclerosis.
Analysis of human studies examining autoimmune markers in patients with atherosclerotic disease.

Identification of potential autoantigens such as beta2-glycoprotein I (beta2GPI) and oxidized low-density lipoprotein (ox-LDL).

Main Results:

Evidence suggests that atherosclerotic lesions can be targets of autoimmune attacks.
Specific autoantigens like beta2GPI and ox-LDL are implicated in this process.
A peripheral immune response is generated against these autoantigens.

Conclusions:

Autoimmune mechanisms play a significant role in the development of atherosclerosis.
Understanding these autoimmune pathways is crucial for developing new therapeutic strategies.
Further research combining experimental and human data is warranted.
