Berberine Alleviates Insulin Resistance and Inflammation via Inhibiting the LTB4-BLT1 Axis.

ABSTRACT: Background: Chronic low-grade inflammation is recognized as a key pathophysiological mechanism of insulin resistance. Leukotriene B4 (LTB4), a molecule derived from arachidonic acid, is a potent neutrophil chemoattractant. The excessive amount of LTB4 that is combined with its receptor BLT1 can cause chronic low-grade inflammation, aggravating insulin resistance. Berberine (BBR) has been shown to relieve insulin resistance due to its anti-inflammatory properties. However, it is not clear whether BBR could have any effects on the LTB4-BLT1 axis. Methods: Using LTB4 to induce Raw264.7 and HepG2 cells, we investigated the effect of BBR on the LTB4-BLT1 axis in the progression of inflammation and insulin resistance. Results: Upon exposure to LTB4, intracellular insulin res
