LDL Oxidation & Atherosclerosis

Discover how oxidized LDL contributes to atherosclerosis and the role of macrophages in this process. Understanding these mechanisms is crucial for heart health.

Key takeaways:
When LDL becomes oxidized, immune cells recognize it as damaged. Macrophages engulf it and become foam cells, which accumulate in artery walls. This is one of the earliest steps in atherosclerosis.

Foam cells are the beginning of plaque formation. Macrophages, the immune cleanup cells, absorb oxidized LDL and become bloated foam cells trapped in artery walls. Over time, inflammation develops, plaque grows, and arteries stiffen and narrow.

Insulin resistance ties into LDL oxidation, creating conditions that make LDL more dangerous. Chronic inflammation and blood sugar damage lead to the formation of small dense LDL, which is especially vulnerable to oxidation.
