Biochem/physiol Actions
7-ketocholesterol is a strong inhibitor of cytochrome P450 7A1. It modulates cholesterol homeostasis, cytotoxicity and apoptosis. 7-ketocholesterol stimulates inflammation, growth inhibition and vascular endothelial growth factor. Cellular accumulation of 7-ketocholesterol enhances oxidative stress, endoplasmic reticulum stress and apoptosis in macrophages.

Killer T cells (cytotoxic T lymphocytes, CTLs) maintain immune homoeostasis by eliminating virus-infected and cancerous cells. CTLs achieve this by forming an immunological synapse with their targets and secreting a pore-forming protein (perforin) and pro-apoptotic serine proteases (granzymes) into the
