Vessel-specific signature of TLR expression in human arteries

Blood vessel	Dominant Toll-like receptors
Aorta	TLR 1, 2, 4, 5, 6
Carotid artery	TLR 1, 2, 4, 6, 8
Subclavian artery	TLR 2, 4, 8
Temporal artery	TLR 2, 4, 8
Mesenteric artery	TLR 2, 4, 5
Iliac artery	TLR 1, 2, 6

Human arteries from 6 vascular beds were collected and processed for gene expression profiling for Toll-like receptor 1–9 transcripts. Each arterial territory expressed a distinct combination of TLRs. For each artery the dominant TLRs are listed.
