Area of Science:

Cardiovascular Biology
Translational Medicine
Animal Models in Disease Research

Background:

Atherosclerotic plaque rupture is a primary cause of acute coronary events and stroke.
The precise mechanisms driving plaque rupture are not fully understood.
Animal models are crucial for investigating human disease pathology, therapies, and drug development.

Purpose of the Study:

To introduce a novel murine model for studying atherosclerotic plaque rupture.
To investigate plaque rupture mechanisms relevant to human cardiovascular diseases.
To provide a tool for preclinical research and therapeutic development.

Main Methods:

Development of a novel murine model using carotid artery ligation and perivascular cuff placement.
Induction of atherosclerotic plaque rupture in the murine model.
Characterization of plaque rupture features, including intraplaque hemorrhage and luminal thrombus.

Main Results:

Successfully established a murine model that recapitulates key aspects of atherosclerotic plaque rupture.
The model demonstrates both intraplaque hemorrhage and luminal thrombus formation, mimicking human pathological events.
This model offers a platform for studying the dynamics of plaque rupture.

Conclusions:

The novel murine model provides a valuable tool for elucidating the mechanisms of atherosclerotic plaque rupture.
This model can facilitate research into the development of new therapies for preventing acute coronary events and stroke.
Further studies using this model are warranted to advance cardiovascular disease research.
