Investigation of the T-cells effect to the prediction of the atherosclerotic plaque development in carotid arteries
2022
Zenodo
Preserved Fulltext
To this aim, this study investigates the role of T-cells in the atherosclerotic plaque growth process through the implementation of a computational model in realistic carotid arteries. ...
In brief, T-cells mediate in the inflammatory process by secreting interferon-γ that enhances the activation of macrophages. ...
This model is separated in three modeling levels: i) simulation of the blood flow, ii) simulations of the biological processes within the arterial wall and iii) simulation of wall thickening. ...
