Ghrelin directly inhibited TNF-α-induced pro-inflammatory responses and NF-κB nuclear translocation in human endothelial cells, revealing a specific molecular mechanism for ghrelin's cardiovascular protective anti-inflammatory effect.
Key findingGhrelin inhibited TNF-α-induced VCAM-1, ICAM-1, and MCP-1 expression in human endothelial cells by blocking NF-κB nuclear translocation via IκBα prese
What the researchers found
Ghrelin inhibited TNF-α-induced VCAM-1, ICAM-1, and MCP-1 expression in human endothelial cells by blocking NF-κB nuclear translocation via IκBα preservation — a specific anti-inflammatory mechanism protecting blood vessels from atherosclerosis.
