WebTLR4 expression is increased in obese mice and humans and positively correlates with insulin resistance ( 26 ). In obesity, TLR4 is considered as the main target for saturated fatty acids in the hypothalamus and peripheral tissues that triggers inflammatory response and endoplasmic reticulum stress promoting whole body insulin resistance ( 15 ). WebTLR4 is expressed on macrophages, which are recruited by inflammatory cytokines in tissues such as obese adipose tissue. In addition, it is also expressed on resident, non-immune cells, such as adipocytes and muscle myocytes. 4, 5 Muscle accounts for most insulin-stimulated glucose use and is therefore a key insulin target tissue.
