Toll-like receptor 4 (TLR4) plays an essential role in innate immunity through
inflammatory cytokine induction. Recent studies demonstrated that the abnormal
activation of TLR4 has a pivotal role in obesity-induced inflammation, which is
associated with several diseases, including hyperinsulinemia,
hypertriglyceridemia, and cardiovascular disease. Here we demonstrate that
(-)-epigallocatechin-3-O-gallate, a natural agonist of the 67-kDa laminin
receptor (67LR), suppressed TLR4 expression through E3 ubiquitin-protein ring
finger protein 216 (RNF216) up-regulation. Our data indicate cyclic GMP mediates
67LR agonist-dependent RNF216 up-regulation. Moreover, we show that the highly
absorbent 67LR agonist (-)-epigallocatechin-3-O-(3-O-methyl)-gallate (EGCG3?Me)
significantly attenuated TLR4 expression in the adipose tissue. EGCG3?Me
completely inhibited the high-fat/high-sucrose (HF/HS)-induced up-regulation of
tumor necrosis factor ? in adipose tissue and serum monocyte chemoattractant
protein-1 increase. Furthermore, this agonist intake prevented HF/HS-induced
hyperinsulinemia and hypertriglyceridemia. Taken together, 67LR presents an
attractive target for the relief of obesity-induced inflammation.
