Atherosclerosis is characterized by the build-up of plaque inside your blood vessels. It can lead to stenosis, which is a narrowing of your artery walls. Plaque is a fatty substance made up of:
Cerebral atherosclerosis is a type of atherosclerosis where build-up of plaque in the blood vessels of the brain occurs. Some of the main components of the plaques are connective tissue, extracellular matrix, including collagen, proteoglycans, fibronectin, and elastic fibers; crystalline cholesterol, cholesteryl esters, and phospholipids; cells such as monocyte derived macrophages, T ...

This occurs when a blood vessel that feeds the brain becomes blocked, usually from a blood clot. [3][25][26][27] How to prevent high cholesterol
24S-Hydroxycholesterol (24S-HC), also known as cholest-5-ene-3,24-diol or cerebrosterol, is an endogenous oxysterol produced by neurons in the brain to maintain cholesterol homeostasis. [1] It was discovered in 1953 by Alberto Ercoli, S. Di Frisco, and Pietro de Ruggieri, who first isolated the molecule in the horse brain [ 2 ] and then ...
Because 24S-hydroxycholesterol is more polar than cholesterol, it can more easily pass the blood–brain barrier to exit the brain and pass into the bloodstream, where it can then travel to the liver to be further degraded. [3] [4] This enzyme has also been found at low quantities in the retina, where it performs the same function to a lesser ...
Atherosclerosis [a] is a pattern of the disease arteriosclerosis, [8] characterized by development of abnormalities called lesions in walls of arteries.This is a chronic inflammatory disease involving many different cell types and driven by elevated levels of cholesterol in the blood. [9]
LDL carries cholesterol that can build up in your arteries, potentially leading to artery-blocking plaques. HDL, on the other hand, ferries cholesterol out of your blood vessels and back to your ...
