Tlr4 obesity

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 ). WebAug 12, 2024 · Toll-like receptor 4 (TLR4) is a pattern recognition receptor.

WebMar 1, 2024 · TLR4 KO prevents the development of obesity-related diseases [16], [24], [25] and reduces weight gain in young mice (8 weeks old) fed a HFD [22]. The loss of weight was associated with TLR4 KO-reduced neuroinflammation acting in concert with anorexigenic action in the hypothalamus [22]. WebIn obesity, high levels of saturated fatty acids (SFAs) contribute to adipose tissue inflammation and dysfunction. Obesity-induced macrophage infiltration leads to insulin resistance, but the adipocyte itself may play a role in generating the inflammatory milieu.
