- Octacosanol (OCT) is a key component of policosanol, known for reducing atherosclerosis in animal models.
- The study explores OCT's role in mitigating LPS-induced inflammation in human aortic endothelial cells (HAECs).
- OCT pretreatment significantly lowers levels of pro-inflammatory cytokines (IL-6, IL-8, MCP-1) and related signaling molecules (TLR4, MYD88, etc.).
- OCT reduces monocyte adhesion to HAECs by blocking adhesion molecule expression (VCAM-1, ICAM-1, SELECTINS).
- OCT preserves endothelial cell integrity by maintaining cell-cell junctions (VE-CADHERIN, β-CATENIN, ZO-1).
- The findings suggest OCT's cytoprotective effects contribute to policosanol's anti-atherogenic properties.
