Key result
Macrophage oxLDL ingestion rate strongly drives plaque formation in mathematical modeling.
Why the study?
Atherosclerosis involves complex interactions between oxidized LDL and macrophages leading to plaque formation, requiring qualitative analysis of these dynamics.
Mathematical modeling highlights the ingestion rate of oxidized LDL by macrophages as a critical driver of early atherosclerotic plaque formation.
Model of oxidized LDL-macrophage interaction extends theoretical plaque formation frameworks; leaves open validation before any clinical relevance.
Atherosclerosis, a long-term inflammatory affliction, occurs due to plaque accumulation in the intima, the innermost layer of artery. It is one of the prime causes of deaths from several cardio-vascular diseases. The primary interaction between oxidized low density lipoprotein (LDL) and macrophages in forming fatty steak is presented here in terms of a nonlinear reaction-diffusion system in one spatial dimension under Neumann boundary conditions. Both the spatio-temporal and the temporal models are analyzed qualitatively. Numerical simulations of both the model systems lead to three significant model parameters with respect to which bifurcations are found. Bifurcating parameters indicate possible developments of various therapeutic strategies in order to establish any preventative measures for an individual or group of patients. It has been found that ingestion rate of oxidized LDL by macrophages has a great impact on the plaque forming process.

Debasmita Mukherjee (2022) studied Atherosclerosis. Mathematical modeling of oxidized LDL and macrophage interaction was evaluated on Plaque forming process and model bifurcations. Mathematical modeling of the interaction between oxidized LDL and macrophages indicates that the ingestion rate of oxidized LDL by macrophages has a great impact on the plaque forming process.
