Obesity-associated hypertension is ameliorated in patients with TLR4 single nucleotide polymorphism (SNP) rs4986790

摘要

BackgroundObesity is strongly associated with hypertension. Despite numerous mechanistic links the association is not fully understood. Western diet increases uptake of Toll-Like receptor 4 (TLR4) ligands such as free fatty acids or endotoxin. We recently demonstrated that TLR4 ligands are involved in the development of hypertension. We hypothesized that TLR4 ligands are involved in obesity-associated hypertension and investigated the TLR4 single nucleotide polymorphism (SNP rs 498790). This SNP is frequent, associated with cardiovascular disease and characterized by blunted response upon exposure to TLR4 ligands.
