Summary
Monocyte tethering and rolling on endothelium during inflammation are crucial. Simulations reveal increased flow rates linearly boost rolling velocity but nonlinearly increase contact area and stress in monocytes.
Area of Science:
- Biomedical Engineering
- Computational Biology
- Cellular Mechanics
Background:
- Leukocyte tethering and rolling on endothelium are vital for inflammatory responses.
- Understanding monocyte behavior under shear flow is key to studying inflammation.
Purpose of the Study:
- To model and investigate monocyte tethering and rolling dynamics on a substrate surface under shear flow.
- To analyze the impact of varying flow rates on monocyte-endothelium interactions.
Main Methods:
- A soft solid cell model was employed for monocytes.
- Coarse-grained molecular adhesive potential was used to simulate monocyte-surface interactions.
- A Lagrange-type meshfree Galerkin formulation enabled computational investigation.
Main Results:
- Flow rate significantly influences monocyte rolling velocity, contact area, and effective stress.
- Increased flow rates resulted in a linear increase in monocyte rolling velocity.
- Nonlinear increases were observed in the contact area and average effective stress of monocytes with rising flow rates.
Conclusions:
- Flow rate is a critical determinant of monocyte adhesion dynamics.
- The computational model provides insights into the biomechanics of monocyte rolling during inflammation.
- Findings contribute to understanding leukocyte-endothelial interactions in inflammatory conditions.
