Atherosclerosis is the buildup of plaque on Atherosclerosis is the buildup of plaque on the inside walls of arteries. Plaque is made the inside walls of arteries. Plaque is made up of low density lipoprotein (up of low density lipoprotein (LDLLDL), ), macrophagesmacrophages, , smooth muscle cellssmooth muscle cells, platelets, , platelets, and other substances. It may narrow the and other substances. It may narrow the lumen of a blood vessel and restrict blood lumen of a blood vessel and restrict blood flow. Plaque rupture can induce the formation flow. Plaque rupture can induce the formation of thrombus (blood clot) and block blood flow. of thrombus (blood clot) and block blood flow. This will result in ischemic stroke or heart This will result in ischemic stroke or heart attack. attack.
Formation of foam cellsFormation of foam cells
The first stage in the development of The first stage in the development of atherosclerosis is the formation of atherosclerosis is the formation of foam cellsfoam cells (macrophages with ingested oxidized LDL). The (macrophages with ingested oxidized LDL). The process begins with trap of LDL in the process begins with trap of LDL in the intimaintima, , which lies just below the endothelium (the which lies just below the endothelium (the monolayer of cells lining the arterial wall). monolayer of cells lining the arterial wall). Trapped LDL could be oxidized, triggering Trapped LDL could be oxidized, triggering recruitment of monocytes into the intima. recruitment of monocytes into the intima. Several adhesion molecules are involved, Several adhesion molecules are involved, including vascular-cell adhesion molecule including vascular-cell adhesion molecule (VCAM), integrin, selectin, and others. After (VCAM), integrin, selectin, and others. After entering the intima, monocytes differentiate into entering the intima, monocytes differentiate into macrophages and ingest oxidized LDL. macrophages and ingest oxidized LDL.
Formation of plaqueFormation of plaque
As atherosclerosis progresses, T As atherosclerosis progresses, T lymphocytes, platelets and smooth muscle lymphocytes, platelets and smooth muscle cells also join foam cells, expanding the cells also join foam cells, expanding the plaque size. This involves cytokines to plaque size. This involves cytokines to activate T lymphocytes and growth factors to activate T lymphocytes and growth factors to promote proliferation of smooth muscle cells. promote proliferation of smooth muscle cells. Platelets can also release cytokines and Platelets can also release cytokines and growth factors to enhance migration and growth factors to enhance migration and proliferation of smooth muscle cells. During proliferation of smooth muscle cells. During this stage, a fibrous cap is formed to this stage, a fibrous cap is formed to separate the plaque from the lumenseparate the plaque from the lumen
ThrombosisThrombosis
Thrombosis (formation of thrombus) arises Thrombosis (formation of thrombus) arises from plaque rupture. Macrophages may from plaque rupture. Macrophages may release metalloproteinases and other release metalloproteinases and other proteolytic enzymes to degrade fibrous proteolytic enzymes to degrade fibrous cap, making it susceptible to rupture. cap, making it susceptible to rupture. Plaque rupture activates platelets, leading Plaque rupture activates platelets, leading to formation of blood clots at the site of to formation of blood clots at the site of lesionlesion
